>similar symbology found across the world separated by thousands of years and hundreds of miles

I just don’t buy the idea that these cultures developed the same symbols and similar mythologies. The americas were meant to be isolated until 1491 yet they have depictions of a civilization bringer travelling on a ship and carrying with him the “bag of civilization”. The same bag we see 10,000 years earlier in stone sculptures at Gobekli tepe. And that’s just one example of these synchronous cultural ideas.
