Over 1 million circular stone structures lie scattered throughout southern Africa. Until recently these have been called cattle kraal, of little historic value. Extensive research by Michael Tellinger and others has revealed that these are the remains of a vanished ancient civilization dating back tens of thousands of years. It covered an area larger than modern day Johannesburg and London together. Tools, artifacts, and petroglyphs indicate that the Egyptians and Sumerians got much of their knowledge and imagery from this vanished civilization. All of this is crowned by a stone calendar now called Adam's Calendar that is forcing the academics to question human origins. Scientific evidence shows that this was also a gold mining culture and many prehistoric gold mines are still present throughout the area.
