>How did they doesticated some wild not edible plant into the ancient Corn seeds, a plant that cant reproduce without man intervention?
Corn didnt use to need human intervention to reproduce
We just breed it one way until it lost the ability 

>like any other civilization 
With no wheels?
I mean I get “no iron tools” Becuase Egypt didnt have iron while building pyramids
But Egypt had fucking sand
They used sand in between rock cracks and use tools on them to make it easier to be cut in pieces
You don’t have that in mesoamerica
You don’t have sand!
How did they do this?!?

They didn't need sand (which would have been pretty ineffective anyways), they probably used biopolymer technology. Look it up, in Peru and Bolivia is well known, since the monumental architecture in Tiwanaku has traces/signatures of specific biomatter (also the finishing and characteristics of the stones indicate too much precision and softness to involve any saw-like technology)

Well what you claiming is more x like concpiracy 
My “sand” technique is what historian and “experts” claim for Egyptian pyramid which again, doesn’t explain the meso pyramids
