@Stark one called All Tomorrows. It's a speculative story on how humans would be if they were scattered around different worlds and evolved to adapt to their environments.
@Stark I think I first heard someone narrate it on YouTube. Apparently, after it was written in 2006 has gained some sort of fanbase. The author realized this and plans to eventually re-release a physical copy... supposedly.
A movie would be cool. Or like a documentary but fake.
