Here’s a starting point if you want to try to calculate a paper-to-slab conversion.
ETA: iirc there’s someplace out there that’s dedicated to archiving stuff on fired porcelain tablets.
Yeah, Ancient Romans didn’t know they lived in “Ancient” Rome. There was old shit even way back then. There’s less of an age difference between Cleopatra and the Empire State Building than between Cleopatra and the Great Pyramid.
Civilization only goes back 5,000 years or so, while humans have lived for like 100,000 years. So from a fictional standpoint, it’s interesting to imagine ancient, even advanced civilizations that existed 10,000 years ago that have all but vanished from the Earth.
Cute idea that’s been done many times; but you’d have to explain not only why we don’t find any evidence of that civilization but also something else: You’d have to explain why there isn’t a discontinuity in the archeology of stone tools, with an early Neolithic ten thousand years before the more recent one.
That’s why I postulated a race of genus Homo but not Sapiens achieving civilization 400,000 or more years ago. That’s a lot more time for stuff to get lost.
