Schoch's dating is based solely on geological evidence, rather than information from hieroglyphics or other histories. West points to the period around 9000 ., when the end of the Ice Age may well have affected weather patterns.

496–406 .), the title character solves the riddle with the answer "a human," for an infant crawls on four legs before it begins to walk on two legs, then as an aged person, he or she walks with the use of a cane, or a third leg.

In 1967, Herbert Ricke of the Swiss Archaeological Institute uncovered a temple at the foot of the Sphinx.

At the time the later temple was built, the Sphinx was buried up to its neck in sand and was called Hor-em-Akhet.

The Sphinx itself forms an image of the akhet hieroglyphic when approached directly from Memphis, capital city during the Fourth Dynasty, when the pyramids and the Sphinx are believed to have been built.

It is generally believed that after the limestone bedrock was quarried for stone used for the pyramids, the remaining block was sculpted into the Sphinx.

A sudden, 50-foot drop not far from the Sphinx might indicate an area that was quarried for the pyramids.

and that show no signs of weathering because of water.

Schoch's findings have been widely disputed by other geologists.

Where the granite covering of the temples had slipped off, the exposed limestone beneath was extremely weathered. But there was numerous happenings with nature still like today with mega tsunamis, typhoons, great volcano eruptions and earthquakes.
