There is a great conspiracy that says This was not from wind, sand, rain, stone scavenging. Khafre pyramid at Giza was under sea for a very long time.
Karst undercutting erosion of the Tura limestone cap of the Khafre pyramid at Giza. The erosion turns up parabolically at both ends, characteristic of wave-action induced seawall erosion at 90 degree corners in harbors and ocean breaks.
The Khafre Pyramid shows signs of erosion that seem to have been caused by seawater. The limestone used in the pyramid’s casing (Tura limestone) is vulnerable to erosion when exposed to seawater, while the limestone used in the structure itself (Mokkatam limestone) is more durable.
The erosion patterns match what you’d expect if the pyramid were submerged in seawater with waves averaging about 6 to 8 feet high. The water level responsible for this erosion is thought to have reached a height of 576 feet above sea level.
This erosion is centered around a specific height on the pyramid, which suggests that it was caused by a large-scale flood or inundation, either global or regional.

There was a Geologist who reviewed the Sphinx and said it had been underwater and was much older than originally established. I don’t remember the show or the Archeo- Geologist name. They also explained how the “face” of the Sphinx had been something different, presenting it as a Lion. The show presented the Lions face had been carved into a Pharoah.
Guess it was karma the French shot his nose off.

Hi Dana B. The Geologist was Dr. Robert Shock originally back in the 1990s. Either the History Channel or Discovery Channel did a special on this back in the 2000s, I remember watching. Shock along with I believe but could be wrong, Graham Hancock were involved with showing the erosion taking place on The Sphinx due to natural water erosion during a time before the Sahara was a desert, maybe somewhere around 6 to 8 thousand years BC. I know Graham Hancock has been on a lecture tourer and such discussing the mass distruction and megafauna kill off during a catostrophic period called the Younger Dryess period from 12,900 years ago to about 11,300 years ago, maybe caused by a large comet or asteroid that may have fragmented. One thing for sure. What we thought about history is always changing.
