Space is undeniably fascinating, and it's completely natural to be captivated by the search for extraterrestrial life. However, the key point I want to emphasize is this:

    Our existence proves that life is possible.
While discovering life elsewhere would indeed be extraordinary, it is ultimately within the realm of possibility. What would be truly remarkable is making such a discovery within our lifetimes—that would be the real stroke of luck, rather than the mere fact that life exists.

If life independently started in two places in our solar system in fairly different places, then it would be reasonable to think that it is fairly common and we would expect it in most solar systems. If life only exists on Earth in our solar system, then it's more reasonable to think life is fairly rare.
Also no possible, there's life on Europa and it shares a common ancestor with life on Earth.

Obviously. But it would still be nice to know how probable or improbable it is.

Yes, and if that occurs during our lifetimes, that's the jackpot.

I would guess that now it's quite unlikely, we might be an ant colony far, far away from others. Finding specific biota or small organisms seems like our most effective approach.
