I think its interesting that we are also very biased towards long lasting societies, because they leave more stuff for us to study, and literate ones, because they can tell us with their own words what events there were. We still dont have a complete picture of the battle of Cannae, one of the consequential in all of history, whose effects we are still living with. Writing was only invented 4500ish years ago, and humans are as a species are way way older.
Its fucked up to think about Catal Hayuk, or Utsie.
