And thank you for your reply,
I can assure that all of the information I have posted is both common knowledge within Egyptology, and readily available to all.
The 20 years estimate in fact has nothing to do with Herodotus. Rather, it is based on the estimation of Egyptologists such as Mark Lehner and Zahi Hawass, as well as structural engineers knowledgeable in the subject such as Jean Pierre Houdin.
And I'm afraid, von Daniken is far from irrelevant to this conversation. It was in fact his book, which contains nothing of substance, that was responsible for hoodwinking the uneducated masses who make up the vast majority of the general public into doubting the ancient Egyptians had the ability to build the Giza pyramids. Von Daniken is the one who first sowed that seed of doubt into the minds of the gullible and unlearned general public. And thus he is very much relevant to our discussion.
