That’s interesting, but I wouldn’t doubt it.
I could be remembering it wrong, but I don’t think that the Aztecs even knew who the Mayans were. It was just a general name given to the people who built the structures they used.
I think the Mayans were very advanced (Possibly apart of a highly advanced worldwide civilization). So in contrast to them, most other civilizations would seem less than.
But damnit if they didn’t understand corn😩
