Hoagland is favoring that idea. The foundations of the pyramids would be 200,000 years old. We ought to keep that idea around since it would hard to dismiss outright without putting unnecessary limits on our speculation.
Schoch and West have looked carefully at the erosion around the base of the Sphinx. Their conclusions seem too solid to ignore, that the erosion had to happen when there was abundant rain on the Giza plateau, and that would have to be more than ten thousand years ago. When one looks at the Sphinx dimensions, it is silly to assert that the face and body were carved at the same time, by people who took great care to NOT distort dimensions when building, decorating. Anthony West is a first rate researcher, and it's silly to dismiss his theories just because they don't fit the 'established' notions. Such perspective on the nature of the solar system (historically) is an example of how 'established' notions can be fundamentally flawed and in need of major revision ... masses of evidence were ignored and put aside because they didn't fit the established notions.
