There is no evidence that I’ve ever seen that technologies moved back and forth from the old world to the new world prior to columbus.
So the wheel was said to be invented by the steppe herders circa 3000-4000 BC. But that invention never made its way to the new world until columbus. Same with horses.
from what I’ve seen steppe herder genetics flow from the indus river southward. North india has more steppe hereder genetics than south india.
The hindu nationalists don’t like the tale told by the steppe herder genes.
So how is it that pyramids were built in Mesopotamia, Egypt and Mexico? It can be said that the pyramids of Mesopotamia and Egypt predate the ones in Mexico by 2000 years or so.
Things can be invented in two places at roughly the same time. That’s the current thinking on clovis points.
There are a lot of holes in the archaelogical evidence trail.
My take on widespread pyramid building is that without modern engineering, the only way to build large tall buildings is something like the pyramids with progressively smaller layers. That said I am a believer in pre Columbian contact. I just don’t think that pyramids per se are evidence of that
