And if we find an inhabitable second earth, and we go there, how long until we forget? How many generations focused on survival until the evidence of having come from another planet is lost? How many generations until we imagine that we evolved there?

The story of having come from another Earth, will be passed down, just like the story of our own Creation. But will scientific minds there accept it after 1000 years? or 6000?

"The story of having come from another Earth, will be passed down, just like the story of our own Creation. But will scientific minds there accept it after 1000 years? or 6000?"

Since we are stuck here and are likely to be for some time this is pointless.
