Robert M. Schoch
Robert M. Schoch is an American associate professor of Natural Sciences at the College of General Studies, Boston University. Since 1991, Schoch has been a proponent of the fringe Sphinx water erosion hypothesis.
Schoch received a BA in Anthropology and a BS in Geology from George Washington University in 1979. He was awarded MS and PhD degrees in Geology and Geophysics from Yale University (PhD, 1983). Schoch's PhD dissertation, Systematics, Functional Morphology and Macroevolution of the Extinct Mammalian Order Taeniodonta, was published in 1986 by the Peabody Museum of Natural History.
Schoch has taught at Boston University since 1984. He is an associate professor of Natural Sciences at the College of General Studies, a two-year core curriculum for bachelor's degree candidates. He teaches undergraduate science courses, including biology, geology, environmental science, geography, and science and public policy.
He has received his college's Peyton Richter Award for interdisciplinary teaching. He is a co-author of the college textbook Environmental Science: Systems and Solutions, now in its fifth edition.
Schoch is best known for his fringe argument that the Great Sphinx of Giza is much older than conventionally thought and that some kind of catastrophe was responsible for wiping out evidence of a significantly older, unknown civilization. In 1991, Schoch redated the monument to 10,000–5,000 BC, based on water erosion marks he identified on the Sphinx enclosure walls, and also based on findings from seismic studies around the base of the Sphinx and elsewhere on the plateau. The Sphinx water erosion hypothesis is currently rejected by the archaeological community because of lack of any other supporting evidence for a civilization sufficiently old as well as other arguments. Mark Lehner looked at that the way several structures in the area incorporate elements from older structures, and based on the order in which they were constructed concludes that the archaeological sequencing does not allow for a date older than the reign of Khafra. Archaeologists and geologists have also challenged his geological claims. 
Schoch's arguments were featured in the 1993 documentary The Mystery of the Sphinx, which was aired by NBC and presented by Charlton Heston. Schoch stars in the film alongside author John Anthony West.
Schoch also claims that possibly all pyramids — in Egypt, Mesoamerica and elsewhere were the result of the destruction of an ancient protocivilization in Sundaland between 8000 to 6000 years ago by rising sea levels caused by repeated collisions with comets. In Voyages of the Pyramids Builders he suggests that when its inhabitants were forced out of Sundaland: "That movement, and its cultural legacies over the following millennia, provides the best explanation for the spread of pyramids across the globe." In 2006, at the invitation of locals, he investigated the so-called Bosnian pyramid excavations north of Sarajevo, but he concluded that the site held "absolutely no evidence of pyramids per se or of a great ancient civilization in the Visoko region".
He is also known for his writing on the Yonaguni underwater monuments, where he has dived on several occasions, beginning in 1997. His conclusion from analyzing the formations is that this is a natural site possibly modified by humans to suit their needs: "We should also consider the possibility that the Yonaguni Monument is fundamentally a natural structure that was utilized, enhanced, and modified by humans in ancient times."
Response from other academics
Mark Lehner, an American archaeologist and egyptologist, has disputed Schoch's analysis, stating, "You don't overthrow Egyptian history based on one phenomenon like a weathering profile... that is how pseudoscience is done, not real science."
Schoch has been criticized for his unorthodox idea that Göbekli Tepe, an ancient civilization revealed in an archeological site in present-day Turkey, was influenced by a solar event that may have been witnessed at Easter Island in the Pacific west of South America. Author Jason Colavito suggested he "abandons all reality in favor of a bizarre fantasy".
