What if we really are the only one in the universe at this moment?
Time passes and we manage to do interstellar and even intergalactic travel at some point.
Then millions of years pass by and all, still “Human” but now “N”, civilizations are exploring the universe and if they’ve forgotten or re-learned where they come from they can “discover” far away life that to them didn’t originate from the same place as they did, as we all did. To them they’d be aliens.
I’m sure there’s someone out there that already has done something along those lines. The Expanse on Prime Video had the Martians vs. Humans and they looked quite different in just a few thousand(?) years. Imagine millions of years of survival in opposite sides of the universe.
