It's quite easy to hazard a guess or try and validate one's own hopes towards what they'd like the answer to be either applying science or religion or any other observation.
But Einstein would know without visiting the whole universe it's impossible to answer yet correctly.
If there is, it wouldn't surprise me. But would we be aware of it if it was depending on what is visible and observable by our modern tools to us?
If there isn't, it wouldn't surprise me either. It would be an awful waste of space but then no other living creature would be wiped out if humans got anywhere near them and their resources :o)
If Darwin's theory of evolution is correct, I don't know if we'd want to find out, because we might be little fish for some big mouths hungry on another planet.
Who knows if the creation version is correct either, or what is and isn't omitted from scripture to humans. We don't live long enough to witness some of the real massive awes the universe has to offer. For all I know, Jesus might be what we call an alien not from some erry ferry mystical magical place, but from another planet that brought life to this one, beyond the expanse.
I could be wrong, but if I mixed up some sterile mass in a blender then blew it up, chance of it creating life I think are zero but that's my own observations, so far. I find most explosions wipe things out, not create. So far humans haven't been able to create a single living thing. Only clone copy or modify so it'd be hard to think it was intelligently created elsewhere.
And since life is only our own personal observation, what is life? As they say, beauty is in the eye of the beholder. The rest could simply be a dream we will wake up from one day after we croke. From the creationist point of view, if we're fallen or imperfect and never used to be, how would we know what we were?
But my own wishful thinking, I hope there's life elsewhere in the universe and much more intelligent than us so we have something more to learn from in the future. Could you imagine the real sh&t lag on the celestial-net!! Screw IPv1024.
