Of all the monuments of ancient Egypt, the Great Pyramid of Giza is by far the granddaddy of them all, and the only one of the Seven Wonders of the Ancient World to survive to this day.
It is NOT my intent to prove who built the Great Pyramid and when, but to share compelling evidence that strongly suggests the cartouche of Pharaoh Khufu (Cheops in Greek) that is inscribed inside the relieving chambers of the Great Pyramid (see image below) may have been fraudulently planted (painted.)
I conclude with compelling evidence (or lack thereof) and reasoning why the Great Pyramid was NOT a tomb. If the GP was not a tomb, then what was its purpose? you ask. Although my jury is still out debating that question, I am inclined to believe the original purpose of the Great Pyramid was lost, forgotten, unknown, or simply ignored over the years.
