“Even though certain of the Giza structures are built from the same kind of limestone as the Sphinx, none of them show the same degree of precipitation-induced weathering. . . . The prominent precipitation-induced erosion on the Sphinx indicates that it must have been built when the climate was much wetter. . . . The Khafre complex was built to merge with and complement the Sphinx, not vice versa. . . . Since [the western] side and front weathering is 50 percent to 100 percent deeper, it is reasonable to estimate that the excavation at those points is 50 to 100 percent older than the now 4,500-year-old work at the Sphinx’s rump. This line of thinking dates the original excavation of the Sphinx to somewhere on the order of 7000 to 5000 B.C., a figure that fits with the climatic history revealed in the rain erosion patterns.” -Robert M. Schoch, _Voices of the Rocks: A Scientist Looks at Catastrophes and Ancient Civilizations_, pp.41-43.
An outlook such as this comports with the report of a worldwide deluge within a literal interpretation of the generations as recorded in the Books of Moses.
I would like to be informed as to how studies in plate tectonics preclude, or give answer to, dating the Khafre complex to pre- or post-flood geology.
