The Clovis Theory of human habitation of the Americas has largely been discredited and with it the racist propaganda that proposes that Europeans found the Americas largely uninhabited and without civilization. In truth the early Europeans found cities that were often superior to the cities in Europe, better organized, cleaner, large, etc. Guns, steel and germs destroyed those civilizations and allowed Europeans to conquer and subjugate the native American populations, both North and South. A lot of our history books need a serious rewrite.
Being part Cherokee was aware of this
@Jetty Here's a starter but if you google Clovis and something like discredited you will find lots more.

@Jetty We visited Caral when we were traveling around Peru, it is a fascinating site.
