We often think of aliens as green men with big heads. But what if there is another planet in the universe with humans? (lemmy.ml)

I think a lot of people will be terrified when they find out another planet with humans.

Convergent evolution causing creatures to look near identical to humans? Probable. The universe repeats. You got the same boring suns, planets, planetary properties, and material/building blocks. DNA can only be configured in so many ways as it is bound by the constrains of physics so ecological niches should remain somewhat the same assuming the planet share most of our settings (size, gravity, moon, sun distance, oxygen events, water, etc).

Literal humans? Highly unlikely. The evolutionary trajectory of a planet would need to be near identical to ours, with historic events coinciding with our own. One random meteor out of match and everything would change.
