"New" find... 3,500 years older than Machu Picchu

[Byrd]

I think that people are generally unaware of just how old the cultures and civilizations in Central and South America are.  800 BC isn't that exciting.

The oldest traces of humans in Central/South America include Monte Verde, estimated to be over 14,000 years https://en.wikipedia.org/wiki/Monte_Verde

And earliest "civilizations" (cultures) show up about the same time that the Egyptians and Hindus and Chinese civilizations are getting a start:  https://en.wikipedia.org/wiki/Mesoamerican_chronology

So...when you see "ancient" being gushed about, stop and take a look at the whole region... https://en.wikipedia.org/wiki/Peopling_of_the_Americas
