Well worth the time reading, for anyone unacquainted with ancient (3,000 B.C.) S.American societies.

3. I lived in Mexico/Central & SA, visited a lot of the pyramid sites. What always surprised me

What always surprised me were the miles around these sites full of rubble/rocks, plowed fields with piles of rubble push to the sides. All the 'locals' in possession of some small relics and bits of artwork, pottery items.

These were huge civilizations and so much is totally lost. Built upon or perhaps still buried for future discovery.

I think these people traveled the entire route from the tip of south America all the way along the coastlines perhaps as far as Russia across the bearing landmass & back again. I don't believe they just walked these vast distances either. They had to have used the seas/rivers and maybe even rode horses for thousands of years longer then currently 'believed'.
