Sitchin's The 12th Planet is always an interesting read. Very similar to text written by the Hindu's, at least 3 to 4 thousand years ago. Ancient China also has similar beliefs. Even some of those stories drifted over to the America's, north, central and south.
The 5 major tribes of Mexico and the Maya's and Inca's cultures had the common belief that yellow haired, blue eyed very tall white people gave them the knowledge of building and other forms of civilization. All these races agree that the white people came from the east in ships (water or air?). That may be why sun worship is so important to them, because the sun rises in the east, the so called home of the givers of knowledge. The white's left, going back to the east but did promise to return some day.
Who can really know. But the common link between the America's (north, central and south) and the mid east/Egypt and Asia are the basic design of pyramids. Also a somewhat similar forms of astrology, a very important factor with all, was found in all these cultures. The sun and venus being of main concern with religion,weather and crop planting/harvesting.
