I agree. Another aspect to consider is the river valleys. If the worlds oceans were 300-500 feet lower than present (and the Med possibly even lower), rivers like the Nile would be in deep river valleys and not prone to flooding as it is today. If the Sphinx was there (as some suggest) 9,000 years ago, it most certainly would have been high and dry.
In 1991, Dr. Robert Schoch, a prominent geologist and professor from Boston University examined the unique weathering patterns on the Sphinx and its enclosure. His conclusions, which came after several months of analysis, were to convulse the world of archaeology. The vertical weathering patterns on the Sphinx and its enclosure, Schoch argued, were not caused by wind effect, as had previously been thought, but by water -- water from torrential rains pouring down in sheets over these ancient structures. But how could this be? Was Schoch saying that such heavy rains only fell on the Sphinx area but nowhere else at Giza?
That was impossible, retorted the Egyptologists. Not impossible, said Schoch if it is conceded that the Sphinx was built at an epoch when such rains were common in this region and that the other monuments at Giza were built long after these rains had stopped. Again impossible, replied the ruffled Egyptologists. Schoch politely shrugged his shoulders.
