The Mayans, Aztecs, Olmecs, and other Indian tribes built pyramids similar to those of the Babylonians, the Egyptians, the Sumerians, and the other European cultures that were across the ocean. They may have once knew that a supernatural Messiah would be born of a virgin, and His blood would be spilt for thier redemption. However, they could have lost this true meaning through Nimrod's teachings, thinking instead that the blood of innocent children and virgins would please their gods. Since these rebels could no longer speak the same language, they never had the opportunity to communicate together again to find the real truth. Instead, they spread across the globe, building pyramids, worshipping the stars, and sacrificing virgins and children on their altars to false gods.
Many evolutionists believe that cavemen evolved from apes thousands of years ago.
Millions of fossils have been found since Darwin's theory of evolution, but not a single transition fossil has ever been discovered between any species, including man and animal. A better explanation of cavemen is found documented in the Book of Genesis. It seems that after the confusion of languages at the Tower of Babel, all of the tribes began to scatter across the land. The strongest tribes probally kept the best land, as the weaker tribes had to travel to the more remote areas. These tribes carried with them the knowledge of husbandry, ceramics, metallurgy, writing, etc.
