They were also about as complex and technologically advanced as their Old World counterparts. I'm consistently impressed by how well South American cultures understood the cosmos, plumbing, irrigation, materials, etc... South American civilizations would have been a source of new information, and no doubt a bunch of knowledge was lost. We only have a few books left from thousands of years of civilizations. It makes me incredibly sad to think about the history we lost. It would be like if we only had one or two books to understand all of Roman history. Absolutely blows my mind how fragile everything we've built is.
