Well done. Indeed the Egyptians landed 2500 BC and stayed to 2200 BC...
The reason this fact is being withheld by the Egyptian government and the Smithsonian Institute, a US Federal organization, is that it would destroy the Darwinistic Evolution Theory and confirm the Biblical accounts as in Gen 6:1-4. There were giants on the earth before the flood, and after. Giants don't fit well in the paradigm taught today. What do Egyptians have to do with giants?
They were their gods - 2/3 divine, 1/3 human.

Excellent write up!
