I have often wondered if the totally barran Empty Quarter might have been created by a boloid strike many years ago. Perhaps the time of Soddom and Gammorah.
Judging by the sheer number of stone ruins identified in Saudi Arabia, as well as in other research in Jordan, there may well be a million such sites scattered throughout the Arabian Peninsula, said David Kennedy, an archaeologist at the University of Western Australia who led the study.If so, there would have to have been a regular water supply; the Arabian desert was still in the process of drying out 3000 years ago, and was a savannah perhaps 5000 years before that. During that 5000 years, 200 sites would have to have sprung up every year to make a million. This DK fellow must have been referring to the extent of the open spaces yet unexplored.
