We are the only life form of the univers. Not even the only intelligent, but the only one. My arguments are:

Life is absolutely everywhere on earth. There is not a single isolated island or deep trench in the ocean that is not covered by life. If life can live elsewhere, univers would be covered by life. Some bacteria would have been ejected into space by some cataclysme and had colinized nearby planets. Kind of Fermi’s paradoxes.

Antropic argument. Our universe is suitable for life because if it weren’t, we simply wouldn’t be there. Add it to Okam razor. If a smaller, simpler, universe could handle life, we would be in that one. Not our current one.

“Our universe is so huge, so there must be other life form” is not the right statement. Our universe is so huge because it is the smallest universe where life could potentially appear.

Only my opinion, not a scientific demonstration.

    If you’re assuming that life outside Earth would look the same then I’d lean much more heavily into saying you’re right. But I think your premise is completely off: why would it look the same as it does here?

    And I also think you’re ignoring just how vast and empty a lot of space is. Everything is spread completely apart. The universe really could be full of life already but it’s simply too far away from us for us to see it.
