Yes... Mayan & Aztecs were advanced in their science!<quoted text>
Mayan math and astronomy was as advanced as that of Europe. Aztec medical science was superior.
You cannot compare civilizations. They each have gone in their own directions. The development of non-European civilizations was largely stifled with the onset of Eurocolonialism.
Europeans were building on a legacy which included the Balkans, Greece, Mesopotamia, Egypt, and to some extent India and Africa.
European do not get full credit for any of it. Nobody does.
Much of their engineering was well behind... They didn't have wheel vehicles which Europeans had for about 5,000 years or more evidence suggests!!
Aztecs didn't have anything like Guthenberg's printing press which was before 1519!
They certainly didn't engineer the kind of guns that Europeans were manufacturing at that period!!
... Anyways.....What race were Kukulkan & Quetzecoatl who had bought them civilization!?
