“There is no “contrary evidence”. “
Of course there is contrary evidence. Nearly every geologist who has examined the features disagrees with Hancock and Schock. They don’t disagree simply because they don’t like those guys. They cite plenty of evidence for their disagreements, but of course, it’s not really what you are interested in, so I guess you will just pretend it doesn’t exist.
“Runoff water only causes erosion at the bases of the structures...”
Blatantly false. Runoff erosion mainly erodes preexisting weak faults in the bedrock, especially in very easily eroded rock like the Giza limestone. Those faults tend to be vertical, and thus flood runoff is the prime candidate to explain the most prominent erosion features we see around the Sphinx enclosure wall.
“BTW..I “am” a scientist. Retired PhD chemist”
Obviously not a geologist, and you should probably read more about geology instead of just taking one guy’s theories at face value because he is doing you a disservice since he’s clearly either incompetent or dishonest.
Those features are not the evidence cited. "Most prominent" is not "most relevant". I am not the party ignoring data...you are.
Get lost.......
