How likely do you think extraterrestrial intelligent life is?

[Anonymous No.8268860]

A lot of people think it's likely. Given the sheer size of the universe, some life somewhere must be intelligent like us, right? But is that really a good argument? I don't think it's likely. Think about it.

Human level intelligence is a result of a series of very specific environmental pressures throughout billions of years, and organisms adapting to those pressures. The "classic" alien we usually think about when we think the word "alien" is a hominid-like organism able to build civilizations, basically just a copy of humans, except more advanced maybe. To get something like human-level intelligence elsewhere, you don't just need a planet within a habital zone, you need a planet that has Earth's exact history (ice comets coming and flooding the planet, amino acids and other life ingredients forming, the evolution of eukaryotes, the evolution of multicellularity, the evolution of sexual reproduction, the evolution of brains, etc.), size (roughly, as animals evolve to adapt to gravity), and a bunch of other factors I'm probably leaving out; pretty unlikely.

We have multiple sentient animals on earth. We are the only ones that are sapient ( that we are aware of). Dolphins, The octopus elephants, and some birds are very intelligent.

I think soon we will learn that life is an inevitable byproduct of cosmic evolution

The nature of chemistry and thermodynamics is such that proto-life is likely to be a very common phenomenon. Would be very surprised if there wasn't abundant subsurface life in our solar system on Jupiter and Saturn's moons.

Think about this: life at any instant is incredibly improbable and rare. Only for a cosmologically tiny fraction has Earth itself been inhabitable. Mars may have had a habitable surface in its distant past. Titan may have a habitable surface in the very distant future, when our Sun becomes a red giant.

So life itself is rare, but mostly likely not on a cosmological scale. But how about intelligent life?

If you believe evolution, it is almost an inevitability, given that a planet or moon's conditions last long enough for significant natural selection to take place. After all, what possible string of mutations is more beneficial to survival than intelligence? If there is a Petri dish of life on some distant planet, the lifeform which mutates some sort of self sentience, or ability to manipulate tools and its environment, will be at a significant advantage.

Even if such a mutation is initally very rare, it will be aggressively selected for in following generations and snowball, because intelligence is the ultimate survival aid.

It really seems to me to be a systematic certainty on a large enough scale.

[Anonymous No.8271802]

>>8271737
There is no precedent to think that life needs to exist in water, have amino acids, or be multicellular to be intelligent. That's just our experience in Earth, and all life on Earth follows these tenets because they most likely all come from the same common ancestor.

For all we know sentience could exist in some amorphous blob of molecules held together as one "cell".

The only thing we know for sure is that the starting point was most likely self selecting chemical or prebiotic reactions.

Evolution could take many twist and turns from that starting point, creating a totally different branch of "life" (which at this point is defined by no more than its property of unergoing natural selection)

I saw a series on the possibility of life and its ludicrously likely that there is another planet supporting intelligent life. Of the trillions upon trillions of stars, each having varius gravitational pull as well as composition and orbiting entities, there must at least be one case in which the planet is of a good distance away from the star to nurture life. Life can also exist in places that are incredibly hostile. There are living organisms, that we know of now, that can survive the vacuum of space for instance.

And life on earth is also not billions of years old, by the way.

>bait taken

[Anonymous No.8271835]

The problem with any claim at the likelihood or unlikelihood of intelligent life existing is that we have no idea what conditions are required to produce life, meaning we don't know how specific they need to be or how likely it is to take place at all even under ideal conditions.
Any realistic statistical analysis of the chance that extraterrestrial life of any kind, let alone intelligent life, exists would need to first take into account the chance that the processes that produce life will occur. The problem with every idiot that decides to claim it's extremely likely is that they're missing this massively important piece of the equation.
If anything, the current position should be that we do not know and cannot know until we have discovered the exact conditions under which life was able to begin on earth with the elements present here.

That becomes a minuscule piece of the equation if the universe turns out to be infinitely big.(Its unknown whether it is or isn't however its looking pretty infinite so far. But even if it turns out being finite it will still be much much larger than the observable universe.)

[Anonymous No.8271927]

I think the main reason scientists, NASA etc are playing up the probability of life in space is PR, to keep up funding.

The thing is, mitochondria within eukaryotic cells, required for multicellular life. Happened ONCE...ever...for all we know.

Maybe it's not just the required conditions we have. Maybe everything needs to happen just in the perfect order. Late heavy bombardment, snowball earth, comet impact etc...

"Life is common" people miss the giant fucking question: where is everybody? Any space faring civilization older than a million years should have colonized the whole galaxy already, and possibly some of the closer galaxies as well. We should be drowning in radio signals from elsewhere, weird spectrum distortions etc.

Guys, self replicating molecules could be weird accident, and cellular life a truly rare freak occurrence...it might have happened just once here. But, there is nothing inherent in our environment that promotes intelligence. Some dinosaurs probably were as smart as birds. A fraction of a fraction of the only intelligence producing line is able to pass mirror test. And that's not enough. Dolphins lack opposable thumbs and therefore will never build spacecraft. Most "intelligent" big apes aren't becoming smarter. They're becoming stronger, because knucklewalking is favored in their environment.

And then, the final nail in the coffin...only the tiny, tiny percentage of all the cultures which have ever existed, were able to form societies where cultural evolution became dominant. And what we assume as homo sapiens inherent tech savviness is freak accident with survival bias, and the true base scenario is more like the aboriginals or pygmys living technologically stagnant/regressing groups, more likely to lose than gain intelligence due to harsh environment favoring smaller less energy consuming brains.

Although it's statistically improbable I think until we know otherwise I maintain that we're the only planet in this galaxy at least that's harboring carbon based intelligent life forms, and we should fucking start acting like it on the pain of death. I mean that in more ways than one.....

Scary as it sounds I believe Humans are the most intelligent beings in the entire universe. Is it really so ridiculous to maintain that viewpoint until it's disproven?

Hell, even if it's false now, having a superior species out there isn't making any difference to us or our planet, for now we live in a separate reality and that's all we should be worrying about at the present time.

I wanna fucking punch people in the face who maintain ''Going into space will solve humanities problems! Lets abandon earth and terraform planets!''

Bunch of fucking retards. Not only are they chasing a pipe dream they're traitors of the highest order.

To add to this;

The conditions for life on earth are perfect for us, and yet the majority of Humans didn't evolve into intelligent, innovative and ordered civilizations, a select few in Europe and Asia did, and they've been dragging the rest of the world along with them ever since.

Look at the world today, 7 Billion people alive and about 6 Billion of them are uncultured, regressive retards who if unchecked will destroy this planet and plunge us into a dark age we will never recover from.

This is all on a planet perfect for supporting life, and only a select racial and cultural minority managed to elevate themselves due to evolutionary pressures.

What the fuck makes you think intelligent life would succeed to the same extent certain Europeans did on other planets even IF they exist and are perfect for supporting life?

Clearly having the perfect planet isn't enough, or else all 7 Billion Humans would be at a similar evolutionary and intellectual level, but guess what, we aren't.

Our unwillingness to rectify this is 'the great filter' imo

Remains one question: Why even care? Does it really matter to us if human civilizations peters out some time after our own deaths, and the deaths of everyone we will ever know?

I know we are "supposed to" care, for some people's political correctness.

But why should we want to? What is human civilization for? What is its purpose?

Some people will say "happiness", but that's not really realistic. Most people are preoccupied hating each other's guts and generally miserable. Then they die in shitty ways to profit the medical industry. That's hardly going to go away.

Some people we need to save life itself, but life naturally goes exctinct eventually. Extinction is a natural inevitabilty and a part of evolution.

Some people say we need to care about the species itself, as if somehow it were a replacement for God. But it's just a biological signifier, it has no intrinsic worth or divinity.

Some people say God, but come on. Even if a God existed, surely he could save his own creation if he wanted to.

Amino acids aren't very unlikely and there's quintillions of stars out there. Who says intelligent life has to be anything like humans or have anything remotely similar to our history?

Nobody has an answer for you OP because we do not know. We haven't been able to check very thoroughly at all and won't for many centuries to come.

tl;dr whole thread but I think this guy makes some excellent points

Short summary:
-life is common
-multi-cellular life is uncommon
-intelligent technological life may be rare or even mythic
-Earth is early
-Humans possibly a first generation intelligence so little chance of any life as advanced as us being nearby.

Man, I don't know. The universe is so fucking huge, and ever expanding, I'd be surprised if any two sentient species could make contact.

>Population
Correct me if I'm wrong Isn't the population currently rising, reach its peak in 2020 or 2030 (I forgot which), but suppose to smooth out and later drop?

I mean if you really wanted to curve population growth massive non-stop genocide in Africa and Asia would do the trick easily.

>Environmental Impact
Aren't we already doing slow processes to fix that?

The problem here is you're assuming Earth like life is the only possible way for life to happen. We have a sample size of a fraction of a percent and you think that's enough to make an assertion?

This is pretty much my stance on the matter as well - We're obviously the first intelligent ones to the party in this galaxy, and probably the only sapient beings at the moment, period.

Hell, the majority of the world's population still have the behavior and (imo) intelligence level of primates.
