How can the Great Pyramid be a water pump when there is no water near it?
If a pump is a pump, it doesn’t matter where the water is; it is still a pump! There is no water near the Great Pyramid, NOW, to be sure. But that has not always been the case. Perring himself, found “Nile Earth” (which is understood to be dried mud) in the Great Pyramid and Herodotus describes the Great Pyramid as being surrounded by water. There is much evidence of water on the Giza Plateau. The Pharaoh’s Pump did have a readily available source of water. Herodotus wrote about an artificial duct connecting to the Great Pyramid..
