were there stone age cultures that still only hunted and gathered in old mexico at the arrival of the spanish?

Alright Indians are not as backward as you think them to be or helpless. The fact is Europeans did leave Europe for more resources and Ideas but at first it was to search for a better route to Asia for trading. But what Europeans did do was find great builders and mathticians, you know native Indians taught Europeans geometry and algebra? As well as medicine and good hygeine? So actually europeans sailed the world stealing and exploiting what wasn't there's to begin with. India and china had antibiotics before Europeans did, but to Europeans they created and invented everything, wrong and not true. That's a fact and if you listen carefully in history you would know that. Native Americans/idians were genius at farming, they were the first crop engineers, they actually created corn, potatos and tomatos, which Columbus took back to Europe and potatos kept Europe from dying from a huge starvation....also what millions of Indians died of was the Flu and small pox both European diseases...if indians hadn't been wiped off by these diseases they would of kicked out the Europeans for sure and that is a fact. Indians had no immunity to european diseases. Did you know Vikings actually discovered the Americas before Columbus? But the Vikings didn't exploit the natives like europeans. Its also a huge misconception that all europeans are white, southern europeans are mediterraneans that is a mixed race from mideasterners and blacks. Southern Europe include, Spain, Portugal, Italy and Greece. Spain and Pirtugal in south and central America as well as mexico. The Brithish in the USA, Australia, Canada.
