The Native Americans

I recently read about Native Americans, both in North and South America; and how impressive some of them were, in particular: the Aztecs and the Incas. I was completely awed by the advancement the Incas had made before the Europeans arrived on their land, both in land usage and socially.

The foreigners only outsmarted them with fire power, and nothing else. Otherwise, the Incas were much more developed in certain areas than the invaders; the Europeans could have used their building technology, and irrigation of hillsides using terracing technique.

I read too, the awesome 'commandments' of the North American natives: of which I reproduce.
