I’m not referring to pits, I’m referring to the deep vertical channels which are a hallmark of flood erosion constrained in hard bedrock channels. He ignored that fact completely.
Why should he not have ignored it...that type of erosion is irrelevant to his point. I repeat...the RELEVANT type of erosion is that which is evident on the TOPS of the structures, and totally unaffected by "flood erosion constrained in hard bedrock channels". That erosion is ONLY caused by long-term exposure to heavy rainfall. The Sphinx and the structures around it have such erosion. Other structures in the same area do not. The climate that would yield heavy rainfall had been well over by the time of the supposed accepted age of the Sphinx.
