i’m not aware of there actually being any evidence for us being the cause of other humans going extinct, could you cite a source for that?
To my knowledge we don’t really have a clue what killed them, and the best bet would just be “skill issue” basically. The world changed, they didn’t manage to survive the changes, we did.
