You're the bloody one, and I'm delusional?

CONSERVATARD!!!!!!!!

What I find intriguing about the theory, is that it raises other questions. Assume that immigrants to the New World did come in waves. It raises questions about the different ethnic makeup of the tribes inhabiting different areas. We tend to think of "Native Americans" as a monolithic group. In reality, there were enormous differences between let's say the Eastern tribes (say the Iroquois)and the "Civilized Tribes" (say the Creeks) and the Plains Tribes (say the Lakota) and the tribes of Meso-America (say the Aztec). They spoke different languages, but often they even looked different. Perhaps this had to do with the ethnicity of their ancestors. Remember an earlier point I made about frequent drought pushing people out of the bulge of Africa? Ever hear of the mysterious Olmec civilization in Central America which predates the Mayans and the Aztecs? Take a look at one of their sculptures:

There have been reports that they found Cocaine in the burial sites of ancient Egyptians. That plant comes from the Andes. Maybe ancient man simply got around more than we modern men are willing to give them credit for. And the thing is, once a group found a rich hunting or fishing ground, they tended to keep that information to themselves. We know know that European fisherman had been fishing off North America (the Grand Banks) for years before Columbus.

Indeed, Many of them never really understood the Europeans concept of land ownership. They might have laid claim to a tradition area, in which their tribe hunted, fished and planted; but the European concept of a single homestead, owning all the land around it, which it fenced in, was alien to them. The European mindset had been formed by 10,000 years of agricultural society. Whereas the Native Americans had come to agriculture much later. One thing agriculture and use of domesticated animal does, is make you susceptible to diseases, which can and do jump from animals to man. The Native Americans had few, if any domesticated animals, especially large herbivores. That held them back technologically. The Mayans made round calenders, but never invented the wheel. Why bother, when they lacked the large domesticated animals that would have made the wheel useful.  Over time the Europeans came to suffer from, and developed an immunity to many diseases. To the point where many of them came to be thought of as "childhood diseases" - like measles, for example, which took a horrific toll of Native Americans.

It also might have had to do with the restricted spaces they inhabited. If you dwell in a small city state with nothing around it but a few of your fields, and then jungle it might not have occurred to you. Also many of the areas where the wheel was first developed had large open areas - think of the Fertile Crescent, Egypt The Indus Valley, or the Yellow River Valley. they also had large scale movement and  trade in bulk goods, like grains. Even groups with domesticated animals - like the Incas - didn't really have open area suitable for wheeled transport. Their mountain road system didn't really allow for it.

Maybe not, but doesn't it seem like it would have occurred to them when they were building all those pyramids and other things?  And moving all that dirt to make mounds?  They used baskets.  Seems like somebody would have had an epiphany.  Especially since they predicted the end of the world in December 2012.
