In his book "Dead Men's Secrets", author Jonathan Gray provides a comprehensive list of megaliths found world-wide. He also makes some astute observations, such as the fact that these world-wide ruins "generally resemble each other in construction, as well as in geographical and astronomical alignment". This similarity is even more striking when you consider the precise construction and colossal size involved- for example, 100 ton blocks miraculously moved miles from a quarry over treacherous terrain (something impossible even for our cranes until recently, which would still be incredibly difficult) and then fitted together so well that a knife blade cannot be inserted between them. Here is a list provided by Mr. Gray of the megaliths remarkably found around the world:
We can also add to this list:
What conclusion can we determine given that these megaliths are virtually identical in construction, style, size, purpose, alignment, and in some cases, heiroglyphs? Particularly given the fact from our maps section that, on at least one occasion, there was a world-wide global survey? Think about the biblical story of the Tower of Babel (also found in other cultures), when man supposedly only spoke one language.
Logically, the only answer is that at one point man was ONE global civilization...
