imo the best example are these vases that were found everywhere in egypt near these sites.
they are basically perfectly machined with insane precision thats impossible to achieve by hand and made from some of the hardest granite that exist and they have often really crazy features.
and they didnt just make 5 of these perfect vases, no, there are over 60k of these out there so they were clearly mass produced. nobody can explain how they were made or what tool produced them.
after laserscanning them it also turned out that these vases are made according to complex mathematical formulas.
so what machine lets you input math and then give an output?
has to be a computer, kinda everyones guess what that might have looked like.
