Can someone genuinely tell me if humans are likely to find out alien life form and if so, when? Could just be acknowledging that life form exists, taking pictures or even seeing these aliens. Not aliens per se but just life form on another planet. How likely is it that we will discover something?

Highly likely that it's out there given the amount of space that exists. Not so likely that we'll find it. Even less likely that when we do find it, it's intelligent and not a bacteria or something.


If we do find anything it'll probably be a bacteria or some kind of micro organism.

In terms of actually knowing of their existence.
Highly unlikely: simple forms of microorganisms.
Practically impossible: anything beyond the former.

In another planet what you will see is oxygen or someother highly reactive gas molecule in the atmosphere with the help of an spectrometer and the Sun the planet orbits around. That means that there is something in that planet actively keeping that reactive compound in the atmosphere and has probably been doing that for million and million of years.

Thats the only picture you can get from the lifeforms of another planet.

How possible is it? If you consider a lifeform a system of self-preserving biochemical interactions(and not just carbon atoms disolved in water doing nasty things with Sulphur, phosphate and nitrogen), then highly probable we might have even looked at a planet with life but we simply dismissed it as imposible to hold it either because living conditions would be too extreme or because doesn't fit with our current understanding.

And if we start talking about which level of complexity these aliens reached, they are probably still bacteria or protozoas, have in mind that before becoming animals we spent a huge chunk of our time on the Earth being simple bacteria, so if to any given planet the segment of time where life exist is dominated by bacteria the chances of finding the other small part with spectacular animals are pretty dim.

Proably find bacteria or something


We will destroy ourselves before finding intelligent life, If Aliens were near they would already be here.

There is zero data to allow for even a rough probability to be calculated. You like to think there s life out there-- cool, me too. But just say that, don't try and act like you have any idea how likely it is.

that picture looks like something an AI would come up with if its given the task of imagining organic life.

Highly likely. We're constantly finding life in horrifically-inhospitable places here on Earth, meaning more and more planets out there could possibly harbor life. Further, we're constantly improving our planet detection and atmosphere spectrometry methods, which improves our ability to find those planets and see if their atmospheres contain biomarkers.

I think we're pretty much guaranteed to find alien life in the next 100 years. But it'll either be microscopic, or so distant that all we can tell is that something is alive. Like by finding a planet with oxygen and hydrogen in it's atmosphere.

Not really... We don't know how life began here, so we can't tell likely it is to happen somewhere else. Sampling size of one is a bitch.

We have some ideas for abiogenesis, and even some experimental evidence of how it might have worked, but no evidence that those experiments correlate to anything that happened here.

We're not even real solid about how many planets there are - we just know there's probably a lot, and that estimate keeps growing. A lot of worlds may be habitable. We're starting to get hints that our variety of solar system may not have the most ideal conditions for life, compared to others that are more common, but as we can't visit those solar systems, and as no one's visited us, it's pure conjecture.

Just because it's habitable, does not necessarily suggest life will happen. All life on this planet is related to one another, suggesting it either only happened once, or the first life quickly overran all other instances. No one knows.

Still, assuming the rest of the universe is just more and more of the same sorta thing, it's likely our situation isn't unique - but it could be so rare that it only happens once in a thousand or million galaxies. If so, and our understanding of fundamental physics holds true, we'll never see it.

On the other hand, we haven't even combed our own solar system enough to rule out another instance of it here. We've *probably* combed our own planet enough to rule out another source of terrestrial life, but even then, there could still be a hidden pocket of unrelated RNA life growing somewhere.

Basically, no one "genuinely" knows, and anyone who tells you otherwise is either insane or a con man.

Look up The Great Filter. If we ever find alien life, humanity is statistically likely to get fucked.

Infinite universe + thing with non zero chance of happening = thing happening somewhere at some time
