I think there were older (pre ice age) “modern human” societies before the ones known or admitted to by historians and archeologists. I think the “ancient” societies our historians admit to were built by peoples dispersed from societies that fell, completely, long before them. So many of those societies seem to have “suddenly” advanced in many ways. The (i call them silly) “Ancient Aliens” theorists explain all that as “gifts” (knowledge and technology) from “Aliens”. I think the “advancements” came from rudimentary understandings, among the widely dispersed peoples, of advancements from the long lost pre-Ice age societies.
I like my theory more than the “Ancient Aliens” one.

So do I, it’s a better theory than ancient aliens.
the simple fact that no tooling has ever been found to cut granite has always swayed me back to the alien side...
