earth is not a planet?

space be very big

>>12109520
It's too large, it's like claiming you're alone in your entire city just because your street looks empty at a given hour.
>>12109528
What

Our galaxy is incomprehensibly large to most humans, let alone our universe.

1.) space is big, light is slow
2.) big filter(s)
3.) we are not, but they have no reason to talk to us, just observe us like we observed harambe

>>12109534
Not them but maybe earth is not a planet could mean that its just a simulation, and in a simulation you can make it so that only one group of life forms developed.

I think another possibility is the anthropic principle. Bamely, we might not be around if some super civ vacummed up the earth or our star a billion years ago, hence their absence. Though this does not exclude primordial life elsewhere now.

>>12109551
Basically this. Every time an advanced human civilization has come into contact with a primitive civilization, the primitive civilization has been swiftly destroyed. Aliens are smart enough to get here; they should be smart enough to preserve humanity the same way we preserve animals in Antarctica.

the requirements for intelligent life (at least as we know it) are too incredibly specific and difficult to replicate

>>12109671
Meaning that since we can't even tarraform the Sahara desert, never mind Mars, we will never be able to re-create the mind-bendingly unlikely conditions that gave rise to us. We will also never reverse engineer the brain for a similar reason. We're just too dumb for that.

>>12109520
if you're going to ask questions that no one has any real answer for other than what amounts to an guess, educated or not, why not ask the big ones, like 'what came before the Universe?'

>hurr durr space is like soooo big dude
You fucking idiots, that's not an explanation. Sure space is big, but the odds that we would not have found ANY SINGLE SHRED of evidence of any kind of life using highly advanced equipment nonstop for decades is absurdly small. It's so small that in fact, it's actually very eerie, there are no signals, no structures, no waste, just silence. It doesn't make logical sense and if you think its just because space is "really big" means you haven't done any research on this topic and have no idea what you're talking about.

>>12110278
>highly advanced equipment nonstop for decades
First of all it's only advanced enough to peek into the atmospheric composition of very specific planets that happen to line up with their stars. Second it hasn't been that advanced for decades. We just barely got fuzzy ass pictures of a black hole and it's been more than a hundred years since they were theorized.

>there are no signals
Our signals barely reach pluto to get them to other solar-systems we would need to invest a lot more energy and or direct them to an extremely small area. Why would a civilization do this?

Interstellar travel is impossible and interstellar communication is pointless.

Life arising out of chemicals randomly bouncing into each other is probably an absurdly unlikely event. I'm not sure why this should be surprising.

are ants cognizant of humans?
when they crawl on a human are they aware they are on a living being?

>>12110278
>if you think its just because space is "really big" means you haven't done any research on this topic
You don't need to do a lot of research to follow the logic. We know the universe abides by certain laws, and those laws allow life to exist under certain conditions. Observation tells us that these conditions are present to some degree in multiple regions of our own galaxy. You know what observation doesn't tell us? How big the universe is. Not just because of the visible light's limited range, but because it is so goddamn big that it looks infinite whenever and wherever we try to assess its geometry. The possibility of life existing outside of Earth is almost infinitesimal; the universe is functionally infinite. It's just physics mixed with statistics.

>>12110278
you're a dunce, fuck off

>We're going to probe the shit out of the milky way looking for habitable worlds, resources and aliens
No we aren't. We are going to be permanently stuck on the few rocks we have in our little solarsystem until our species dies out.

>>12109520
Water is the most abundant substance in the Universe, jet most rocks we found don't contain a bit of that. As if something erased it by force.

This is like asking "why aren't there other galaxies?"
Even the air force released photos of UFOs. Aliens are here and they don't make themselves easy to spot and the government likes it that way. If you're waiting for some stuffed suit to confirm what reality is don't hold your breath, the president won't even admit climate change is real.

>>12109520

>>12110716
>so absurdly advanced that even PhD-level scientists can't comprehend it
It's a plane and a bird the only thing absurdly advanced is the pile of bullshit that pilots will stack when you ask them for a fun story about aliums.

>>12110721
How does this explain the absence of water in our solar system?

>>12110723
Okay, Doctor. Mind if I read your paper on that?

We know for a fact, cause of spectral analysis that water should be everywhere. Its not on Venus, not on mars, and basically not on 99% of all bodys in our solar system.

Of planes and birds doing nothing special.

>We have eyewitness accounts.
Notoriously unreliable because eyes are garbage witnesses are stupid and accounts are just tall tales.

>We have DATA RECORDED BY MILITARY INSTRUMENTS.
No, we have anecdotes about data recorded by military instruments.

>Do you think everyone involved is straight-up lying about the facts?
Is it a lie if you don't really have facts?

>In which case, why bother coming in here to argue?
I was here before you came and shit up the thread with your >>>/x/ tier dumbassery.

>>12110768
Okay, so in other words you're calling "hoax!" Once you play that card, there's nowhere else to take the discussion. You win the argument I guess.

>>12110781
This isn't a hoax, Its a bunch of dumb people getting exited over some videos because they think it proves aliens are real and on earth.

>>12110783
So people believe it because they're dumb? Is that your follow-up argument?

>>12110785
>So people believe it because they're dumb? Is that your follow-up argument?
Sure I guess.
Is your argument that there aren't dumb people to believe this? Because I can cite a thousand sources for mine. Earlier in the summer /sci/ was full of flat earth and electric universe threads.

>>12110792
>Is your argument that there aren't dumb people to believe this? Because I can cite a thousand sources for mine.
Sources that prove the Pentagon's account is in any way untrue? Or sources of dumbasses? Because I'm pretty sure that second one counts as Ad Hominem.

Dumb people often believe the same things smart people do by coincidence. Like, some Democrats are really, really dumb, but they almost all believe masks prevent COVID, similar to every other reasonable person in the world. Turning the focus to individuals unrelated to the actual event just muddies the waters and undermines what facts are available.

>>12110802
>the Pentagon's account
I wasn't aware that the pentagon had a fixed stance other than that those videos were of unidentified flying objects or whatever.

>>12110807
https://en.wikipedia.org/wiki/Pentagon_UFO_videos
>The Pentagon UFO videos are selected visual recordings of cockpit instrumentation displays from United States Navy fighter jets based aboard aircraft carriers USS Nimitz and USS Theodore Roosevelt in 2004, 2014 and 2015. The three videos, widely characterized as officially documenting UFOs, were the subject of extensive coverage in mainstream media in 2017, and later declassified by the Pentagon in 2020.
The US government is not going to declassify a report to contradict the people who wrote it. Bruh, come on.

>>12110813
So what's your argument?

>>12110818
That there is unambiguous data coming from an ostensibly reliable source; it's been seen by just about everyone in the world, and no one can explain it. No one. The US kept its atom bomb project as top-secret as possible, but scientists outside the government could still conceive of a weapon powered by a nuclear reaction. If this UFO was a classified project, and it was initiated so many years ago, some civilian absolutely would have figured out what that thing was made of by now.

>>12110792
Now we have electric flat universe threads.

We're emvolvimg. As Cheems would say.

We're going on a trip, on our secret rocket ship, zooming through the skies.

Little Ein/sci/s.

>>12110858
>unambiguous data
You mean the videos? I can't disagree with you more. If they were unambiguous then there would only be one explanation. Even if you think your personal pet explanation is the correct one you can't seriously say that they are unambiguous.

>and no one can explain it. No one.
Plenty of people have provided plausible and reasonable explanations that do not require assumptions about advanced unknown technology.

>The US kept its atom bomb project as top-secret as possible, but scientists outside the government could still conceive of a weapon powered by a nuclear reaction. If this UFO was a classified project,

This is where you go off the rails. If the US government is keeping secrets why do you think they are telling the truth now.

>and it was initiated so many years ago, some civilian absolutely would have figured out what that thing was made of by now.

But why? Last time I checked there was no magic civilian tool that can be used to determine what objects in a grainy black and white video are made of.

>>12110879
>If they were unambiguous then there would only be one explanation.
Not unambiguous as in "unambiguous proof of aliens", unambiguous in terms of the most basic information available - the numbers. We know how high it was going, how fast it was going, what its shape was; and if we take the pilots at their word, we know its color, and that it does not release any visible propellant.
>Plenty of people
Who? Give me all their names please.
>why do you think they are telling the truth now
Because I am not arguing under the assumption that someone who keeps secrets isn't necessarily going to tell constant, intricate lies. Also, if we don't accept the facts as they appear, how do we stay objective? Like I said before, what's the point of arguing if you've already made up your mind that the report is a lie? Also, why do you concede that some arguments are plausible and reasonable if their premise is based on complete conjecture?
>no magic civilian tool
You would be amazed at what computers can do these days.

>>12110907
>isn't necessarily
Shit, meant "is necessarily"

>>12109520
We are the only ones.

>>12110907
>We know how high it was going,
Depends on the video but sure roughly we know not higher than most planes go.(or birds in one video)
>how fast it was going
Depends on the video but sure roughly we know not faster than most planes go. (or birds)
>what its shape was
I'll fight you on this one we only know the shape of it's IR signature as processed through various lenses and a camera. Which is a blob.

>and if we take the pilots at their word
Why should we? I thought you were doing only unambiguous evidence.

>Who? Give me all their names please.
https://en.wikipedia.org/wiki/Pentagon_UFO_videos

>if you've already made up your mind that the report is a lie?
What report?

>why do you concede that some arguments are plausible and reasonable if their premise is based on complete conjecture
My definition of plausible and reasonable is that they can be explained only using what we can confirm to be true. Planes are real, birds are real IR signatures and optics are sometimes weird. Parallax is real and makes you think things are moving fast. You don't need anything more than that.

>>12110921
>Not faster than planes or birds
Alright. I'm done. If you're going to straight-up ignore actual numbers, then try to eyeball it instead because you think that would be more reliable... we aren't going to agree on anything.

>>12110933
>If you're going to straight-up ignore actual numbers
What actual numbers? Which numbers in the videos prove that these things aren't just planes (or a bird).

All the life is behind a cryptographic barrier, so they just look like random ass dead planets and whatnot.

>>12110947
Not explicitly in the video - from the report. Even the Wikipedia article gives a couple:
>According to Navy pilot David Fravor, a radar operator aboard the USS Princeton told him to investigate radar indications of a target at 80,000 ft. that had apparently moved rapidly down to the sea before stopping at 20,000 ft.
There's a video out there that describes several more fairly precise measurements taken over multiple sightings. Now I have to find and watch it again to remember what they were. Fuck you for making me do this.

https://youtu.be/c7MO3up5bZs

>>12110968
I thought we were only using unambiguous evidence. At this point it's hearsay.

>>12110975
The numbers are 80,000 and 20,000. This should not be ambiguous to you.

Once again, if you can’t even trust the person who took the measurement, there’s nothing to be discussed. It’s just a guy saying some shit that may or may not be true. Notice that you can nullify literally any argument with the phrase “Well, you can’t be *sure*...”

Here, this video has the numbers. It doesn’t look legit, but the sources in its description do. Believe it or don’t, I guess.

https://youtu.be/24cDcY-i1mM

The odds are heavily stacked against us in that theoretically, any civilization would have had time to expand before we even began evolving. There should be some type of evidence to suggest anything like this but there isn't, so it's either a filter or we literally are the one in a quadrillion chance.

>>12110278
The problem with looking into space for evidence is that we are mostly looking into the past.

>>12111008
Not the guy you're arguing with
The numbers have one sig fig. This is not likely to happen in real life, so likely this means they were just estimates, from a clickbait youtube video no less.

>>12109520
There are some great filters pre-space travel that make intelligent life unviable to arise in a volume encompassing our galaxy cluster.

This is the only viable solution, since colonizing one or even multiple galaxies is incredibly easy.

We're not. Life on Venus is going to be announced in a couple of days.

We are the precursors, the old ones, the first species to emerge.

>>12110278
You don't get how big space actually is do you you dolt? There's galaxies we can't even see because the light from them has not had enough time in the existence of the universe to travel to us. Even many of the ones we can see we are only seeing what they looked like millions or billions of years ago. An entire spacefaring civilization could have sprung up and gone extinct in that time and we wouldn't even see their inception yet because they're so far away.
You're assuming there's going to be life the next star system over but in reality we may be the only living organisms in this galaxy while there are aliens a billion light years away.

>>12113260
Two sides of the same coin. But I didn't hear about it from there.

>>12113258
Costs a lot of money. We could have started 50 years ago if we wanted to.

>>12114011
I'm not talking about what we can't see, and that doesn't even matter; we've established the conditions for life and extrapolated the number of suitable worlds (for a low reach number, I might add) and even within our own galaxy, based on what we know using models like the Drake Equation and there should most definitely be some kind of observable evidence of life, and there literally is 0, you fucking stupid moron.

>>12115876
>The models say there should be life in this location and the models are always right even though the fact that there's no life in this location obviously makes the models wrong but I'm still basing my argument which disproves those models on the assumption that they are right

What's the most likely reason there is only one retard OP?

>>12110278
humans are the only species out of hundreds of millions who can create structures and send out radio waves to be detected

there could be trillions of life forms in the galaxy but we're the only ones to get as far as we did

I don't know the answer, but I think people should evaluate the questions with more humility, uncertainty, and agnosticism. I see people who say things like "life obviously must be out there given the probability of it happening across a set of so many planets", and that it's so unlikely, and intelligent life is so much more unlikely, that it must be exceedingly rare.

I think we really have no clue how likely either is, and we might not know for a long time. I think it's totally possible that the universe is teeming with life, or that there's a bit of it, or that Earth is the only life to form so far (or the only complex/multicellular life).

I think if we definitively prove the existence of independently-forming life on another planet in our solar system, then the odds go way way up that there's probably quite a bit of it across the universe. But if we never do find any, it's tough to know, at least until we can more effectively explore past the solar system.

This upcoming Venus announcement is still far away from proof, so don't get your hopes too high just yet. It's interesting for sure, but it's just an indirect indicator which we don't know with certainty can't be produced by non-living things. It'll take a long time to confirm it. Also, if we do discover microscopic life there, it's possible that an absolutely overwhelming percentage of the rest of the life to ever form in the universe is also microscopic, in which case intelligent life could still be extremely rare or maybe even hypothetically hasn't happened elsewhere. There's just way too much we don't know yet.

>>12118526
>I think if we definitively prove the existence of independently-forming life on another planet in our solar system, then the odds go way way up that there's probably quite a bit of it across the universe
What if it's extremely unlikely to occur, but when it does, it spreads throughout its solar system easily? We're only light-minutes away from other planets and moons, but lightyears away from the nearest star. I would say we'd have to find it in another star system, since the distances are so huge that the odds of it seeding from one system to another are minuscule.

>>12111512
that's trivial
Andromeda is <100 million light years away. If alien civilizations are common, then they would have had enough time to colonize Andromeda and be detectable even to our tech even with the 100 million year delay.
>>12111765
lol that's like saying energy is a vector.
>>12118475
>>12112263
that doesn't change the fact that we're Alone In The Universe.
>>12118526
we can actually infer how rare intelligent civilization is by looking at how rare our environment is compared to the common environment.
the verdict is that it's insanely rare.
an intelligent civilization needs to be in a quiet galactic zone between two spiral arms of the galaxy, it needs a quiet but long-lived star (1% of all stars) that won't pummel the civilization's planet with solar winds but will also give the planet enough time to be habitable to evolve life/intelligence/civilization, it needs a weird ass solar system where the jupiters are on the outside and rocky planets are on the inside which is the opposite of common, it needs a jupiter to herd the asteroid debris to make sure the civilization's planet isn't bombarded with frequent impacts, it needs a saturn to pull jupiter back from decaying in orbit, it needs a nearby gamma ray burst to help mutate life, it needs a couple moderate meteor impacts to facilitate evolution but not too much, it needs a large moon to loosen up the crust and cause plate tectonics and also cause tides, etc.

That only if we assume that aliens would be similar to humans (which is a stupid thing to do) in that they are curious and want to explore other planets/galaxies, when they could just not care ( or for some other reason that we dont know about) and stay on their home planet without trying to contact anyone

Omg I love Moby! xD

>>12109520
Because I'm really smart so when you talk to me it feels like no one is actually there.

Even if there is other life in the universe, why do people always assume it has scientific advancement far beyond ours? why do they assume it could even travel through space? why assume that its even intelligent for that matter? I don't get how the idea that "the universe is so large that there has to be other life out there" comes to the immediate conclusion "so it must be klingons and little green men and wookiees"

>>12109520
Literally just efficient, directional signals. Why would an advanced species blast out radio in every direction with enough power for us to detect it? Do you know how much energy that would waste?

>>12109520
Most likely reasons:
A)Life needs very specific circumstances to naturally arise, thus planets that can support life are rare and extremely spaced out from one another. The distances are so large that you need FTL travel/communication abilities for them to know about each other. It's probably impossible for living things to harness FTL.
B)Earth/humans are in a simulation/an experiment/God's pets/etc. etc. and whatever that "God" is, just doesn't want us to meet his other pets or we are the only pets.
C)Life is so astronomically improbable to naturally form that life literally exists only on earth, and has never existed anywhere else.

I don't see how our existence is evidence that there other lifeforms like us in the universe.
I honestly find it more likely that IF there was other life in the universe, it would just be micro organisms or animal-like creatures, nothing like us. Star Trek isn't reality dude.

>>12109520
While microbial life may be common (see Venus news), intelligent life is rare and it is extremely difficult for that life to become spacefaring.

>>12109520
1) We haven't been listening long enough or haven't been listening properly
2) Intelligent life is so rare that it occurs less than once per galaxy or we are among the first
3) Advanced civilizations don't evolve as we might expect them to by building conspicuous megastructures like dysons swarms and instead prefer things like nuclear fusion, black hole farming or some other yet to be discovered energy source
4) Aestivation hypothesis. Advanced civilizations tend to store energy and go into hibernation until the universe cools down so they can compute more efficiently
5) They inevitably destroy themselves before they can plant enough off-world redundancies
6) We're part of an ancestor simulation. Only our nervous systems and immediate surrounding are simulated, while distant stars and planets are merely a projection
7) Intelligent life is so rare that it occurs less than once per universe (or at least of those that are like our own)

Other than that you have nothing to back your assessment as "likely" because it's nothing but retarded and I didn't claim it to be "evidence".

universe big
earth small

>>12110278
it's not only that space is big but cosmic timeframes are so absurdly out of proportion that an entire civilization can appear and then wink out of existence so quickly that it makes sense we haven't found anybody yet

>we are primitive as fuck

as compared to what? retard

We could be the most advanced form of life in the galaxy yet we wouldn't know it

>>12109520
It seems logic to follow that there should be various civilitzations that developed intelligence way before us (+E10 in years), and if they are expansionist and curious (Which is likely) they will expand (maybe not themselves but some other agent they've created) beyond their planet and solar system, galaxy and beyond that. Even if they are not alive anymore,we should be able to see their ruins. The universe is very big but also very old, any intelligent species that was at our current state of technological (or something simmilar) development will have an inmesurable impact in the universe in a long period of time.
So we are very special or there is one great filter (or various) that make this expansionist desire.
Also maybe we are a floating unit of computation in a different reality tricked by someone or itself to belive this is the base reality.

Life arises due to natural process on early earth.
Humans evolve in a timely fashion.(in regards to when they could have evolved)
There are many millions of habitable planets where life and intelligence could evolve.
No evidence of alien intelligence whatsoever.

Solutions :
Abiogenesis is an incredibly improbable process. An incredible luck of the draw.

Life is relatively common but intelligent life is an ever so unlikely possibility. An incredible luck of the draw.

Or... God did it.

jews everyone hates them

Fact that so many people are seething at OP due to his very simple and truthful point demonstrates what a bunch of midwit dogmatic Redditor fags most of sci posters are.

I will add something to OP's question. If we are not alone, as some manchildren here like to screetch about, then how come there has not been even 1 alien specie that has managed to find us and contact us. If we assume that interstellar travel and communication can be improved without any limit and boundary, then would it not be logical to assume that at least one specie would progress to such a level that it would manage contacting or even physically reaching us? In such a vast universe, why has not even one such specie develop.

Then since aforementioned specie does not exist, would it not be fair to assume that if other species do exist out there that we do not know about and that do not know of us, that there is a certain "wall" between us that prevents us from ever finding out about each other, wall being limitations of the specie due to the laws of the universe. And if this is the case is this not the actual "Great Filter"? Following this logic there can only be two versions:
1. Only Earth has life
2. There are species on other planets as well, but we will never learn about each other due to our limitations.

If the second is true, can we not attribute this to a form of divine plan that caused it to be this way, and if the first is true, can this also not be attributed to the divine? How else would our solitude in such a vast universe be explained then.

>>12110278
i think its just that out metaphorical glasses are the wrong prescription. We cant see shit because whatever we're doing to look isnt as advanced as we think it is

>>12121642
Millions of years is nothing compared to universe lifespan. And most of the advances are made rather in an accelerative characther.If we are not extinct in 1000 years we will be likely have colonized our solar sistem.

>>12128421
>How else would our solitude in such a vast universe be explained then.
Random wave functions colliding to another making slef organizing complex creature who through a genetical mutation developed an increment on the size of their mass allowing them o enter other conciousness.

>>12109520
the unimaginable vastness of time and space, coupled with our extremely limited ability to measure or observe it, let alone in real time.

>>12127062
Curious, sure, but why do you consider interstellar expansionism to be likely? It's more likely that any sufficiently intelligent and logical species would have mastered population control and sustainability as a prerequisite to surviving long enough to develop interstellar travel in the first place.

>>12118737
The only things alone in this universe are the single neuron firing in the void of your brain, and yourself as you jerk your needle dick to the thought of people falling for your shit bait.

>>12121614
This is the true answer to almost EVERY question we have in science. Humans are blind retards. There is no fermi paradox, there are not many worlds, humans are just idiots

>>12109520
Our universe is relatively young. Humanity, from the starting point of life, took roughly 3.5-4 billion years to come into existence. That's about a quarter/third of the entire existence of the universe. In other terms, the universe has been around for only 3 or 4 "life units". If we had been around for 30,000 or 10,000,000 or 25,000,000,000 "life units" then I would be concerned about the sparsity of life.

>>12128924
I think it's worth considering that life only took a billion years to emerge once the earth was formed.

>>12111758

>Admit sources are in the description, not the video
>Get completely ignored
Yep, that's good-faith arguing right there.

>>12129369
I honestly don't think that's meaningful. There are probably too many factors to say whether or not the duration from Earth formation to life formation is typical or atypical. On the other hand, the duration from the beginning of life to the organic emergence of sentient beings is likely near optimal and thus can be used as a metric of sorts. That evolutionary span is most likely the same everywhere in the universe, meaning it takes roughly 4 billion years for sentience to evolve organically on any planet.

Following from that, even in the most optimal of circumstances, the most advanced civilization in the universe can't be older than about 10 billion years old. Which is actually a pretty fucking old species. And with exponential growth, who knows how advanced they may be? 10 billion years of unimpeded technological growth could be unfathomable.

>>12109520

There must be some sort of 'great filter' which prevents sentient life from sustainably escaping their homeworld before an extinction event, perhaps this 'great filter' is an extinction event itself!

>>12109531
This, plus intelligent life seems to be hard to come by. Life is far more common than we thought, intelligent life could be the same

>>12109520
Conciousness doesnt exist in the sense it occupies time and space. Its a really effective survival strategy a bunch of apes made a long time ago by living longer than the apes that didn't. Since then we've had to rationalize that mistake with civilization.

>>12109520
Our theories of the universe are just plain wrong.

It's very simple: life is so rare that Earth is unique.

>>12127017
That would be God, my (arrogant) friend.

>>12128924
That's actually surprising when you first realize it. Humans as a specie appeared ~2 millions of years ago. Life appeared ~4 billions of years ago. You'd expect universe to be created trillions of years ago, yet it is only 3-4 times older than life. Earth was truly lucky.

>>12133513
dude, we're on the verge of discovering life on Venus.

also the "rare earth hypothesis" is its own belief, like atheism to religion.

>>12133544
>dude, we're on the verge of discovering life on Venus.
We are not.
>also the "rare earth hypothesis" is its own belief, like atheism to religion.
No, it is a pretty obvious default belief.

>>12133551
>No, it is a pretty obvious default belief.
lol thanks for proving my point

"I see no life therefore we are alone"
"I see no gods therefore there are none"

we can't even see the outer solar system, and the nearest star out of the infinite ones in the universe, is 4.2 light years away. drawing up conclusions and believing shit you think you know all about is retarded.

Anything we might regard as life exists outside of our comprehension.
That is, it is so large, so small, so slow, so fast, that everything it does is completely outside of our frame of reference. Despite containing information, we'd interpret every action it commits as some level of natural phenomenon. And it would never react to us, because we'd be just as incomprehensible to it as it is to us.

>>12133561
Yes, if we look around and see no signs of life, then Earth being the only place with life is the default belief. Disproving it is pretty easy: just show one example of a planet with life.

>>12109520
>Most likely
Pic related. Now take into account the speed of transmissions, and the fact that there is an instantaneous moment where the supposed intelligence must receive that signal. Space is too big, c is too slow.

>>12109531
Spbp. You can check all you want, your efforts are nothing compared to the scale of the universe.

>>12109580
Like how we preserve animals on reservations by leaving them on protected territory only to be very rarely killed for sport or experimented on? Hmm sounds kinda familiar...

This retarded thread again. Its all so tiresome.

>>12128864
I once had a science teacher who described science as "not the search for new information but rather being less wrong about what we mistakenly believe we know."

>>12110693
No, that isn't the most likely explanation. If a human were inside that craft they would be a puddle of mush smashed against the wall.

We are alone because we have to collectively realize and agree that we are not alone and we are far from doing that. Earth is protected by a galactic federation (which is not on earth) treaty because it is a place where souls are coming from the spirit world an having human experiences and we have to evolve on our own without help of et's and other advanced planets but when we collectively realize and agree we are not alone and are collectively as a whole open to it an ready for it the treaty will be broken and aliens and humans from other planets will be able to land openly in the public and comingle among us instead of just at area 51 in secret

>>12109520
I blame the minorities for this one.

>>12109520
I'm not a scientist but I was watching a lecture on the evolution of multicellular life. Anyway, when you look at the three domains of life only one contains multi-cellular life. And even then its one (or two?) small branches with only one common ancestor shared between all multi-cellular organism.

The domaine that contains the most genetic variation is unicellular. The point I'm trying to make is that the evolution of multicellular life is not inevitable. The genes could bounce around forever in all sorts of interesting ways without ever becoming multi-cellular organisms.

>>12118789
If an alien achieves any level of technology and success we can assume they're a lot like us actually, in that they're curious and competitive.

>>12109520
we're not alone if you believe in the multiverse.

>>12109520
Since when is there just one of anything in the universe?

>>12109520
Uh... the strong and weak antropocentric principle, maybe.

Or maybe we are just one of the first, or maybe the others have no interest into contacting the rest (or good reasons to do not get noticed).

Because pee pee poo poo aliens dont give a fuck about you.
