The Mayans and Olmec were absolutely incredibly advanced. 
What is not known is if they (and many other early civilizations) were 
being literal when they recorded being visited by "star people" who 
taught them amazing things.

It could be a very real possibility that the space people were folklore 
and the civilization developed amazing astronomy and mathematics that 
exceeded anything that came after until the 19th century in a vacuum.

Aborigines, many Native American tribes, Mayans, etc. all have spoken 
histories of the star people. Who knows if it's been added to?
