We have all seen the pictures of the pyramids in Central America, and South America; but an interesting fact is coming to light concerning pyramids right here in North America, as well. This video shows one in Illinois; but there are others in different parts of the country. Some are much smaller than this one pictured in Illinois, and in most places they are simply called "mounds", and no one knows who made them, or when. Apparently, even the Native American Indians do not know who built these pyramids either, and when asked about them, will say that they are not part of their culture. There seems to be about three ideas of the origin of these pyramids, both here and in the southern part of the Americas. The most accepted theory is that people who had seen the pyramids in Egypt some how came across and settled in the Americas, and built the pyramids. The second theory, is the reverse, which would be that ancient people from here went to Egypt and built pyramids there. The third theory is that there was at one time a civilization so advanced and so widespread that they traveled all over the world and built the pyramids. That one makes the most sense to me. When I lived in western Washington, there were mounds out there, but they were pretty small ones, and most people thought they were some sort of Indian burial mounds, although I don't think that there was any definitely knowledge of when and how they were built. They are called the "Mima Mounds". Whatever the pyramids are for, they seem to have been built in many different areas all over the world, and some of the latest ones to be found were in Afghanistan, if I remember right, and there are also some huge ones in Russia.
