The innovative technology that powered the Inca

PO1 Tony Holland Fascinating history. Thank you for posting.
When I first became interested in ancient history what we could learn about it when we had no writing was from stonework, art, architecture, and language. There has been so much more learned about the ancient history of North and South America so much later than elsewhere in the world, with a lot still to be uncovered (literally) - many mysteries to unravel still on our side of both ponds.
Articles like this that remind us how folks live today can still tell us a lot about the ancient history of places in some ways, especially when we learn what is traditional about a people's culture, like vestiture, food and the way it is prepared, medicinal herbs and treatments, music, language of course (if we learn it), and as the article tells us - clearly agricultural practices also.

The work of aliens.
