Pyramid carbon dating
It is said that Manetho's main goal was to prove to the Greeks that the Egyptians were the world's oldest people, but that he faced competition; Berosus was trying to do the same thing with his homeland, Mesopotamia, while the chief librarian of the Alexandria library, Erastosthenes, also claimed great antiquity for the Greeks.It was Manetho who compiled Egyptian history into the thirty dynasties we are familiar with today.While most sites are adorned with inundations of praise to the builder of the structures, unfortunately, the Giza complex is devoid of such engravings or inscriptions (exceptions discussed earlier).In itself, the absence of information is significant.Total, 44 years."

In the 1980s several ancient Egyptian monuments, including the Great Pyramid, were radiocarbon dated.
