Comment: I'm not sure the age of pyramids and the sphinz

I'm not sure the age of pyramids and the sphinz

are accurately determined. There was some discussion that geologists noted water weathering and corrosion on them, if that's true they may well be much older and date back to a time the area was tropical. The other thing that's intriguing is the machine marks on the blocks appear to have been made with tools the Egyptians did not have.
