I find it passing strange that the evidence for the height of the Great Pryamid, its supposed special location and its supposed other unique features are so equivocal.
If we are finally convinced that the pyramid is Willowtree's special height and other claims, what does that prove? Anything more than that a couple of statements in the Book of Isaiah are accurate? Did god actually tell Isaiah these "facts"? Does this then prove the existence of a supernatural entity which Isaiah called Lord? Why would the proof of the claim about the Great Pyramid represent "the greatest proof of God's existence"?
