The Great Pyramid of Giza was built to be a reduced embodiment of the dimensions of the earth; its base perimeter is half a nautical mile, and half its base perimeter divided by its height is pi, so you can see that its base is a squaring of the circle of the earth then reduced by a a factor of 43,200, which when divided by 6 equals 7,200, the number of Great Pyramid base perimeter lengths which compose the radius length of the earth. See the explanation of how this was achieved in article #2 at http://IceAgeCivilizations.com, to know the ancient methodology for earth measure (geo metry) is the same concept as our nautical mile mapping system, but achieved by measuring precession time, not solar time.
The Great Pyramid was built as a monument to their ability to measure the earth, built shortly after the Deluge when the great civilizations of the Middle East were burgeoning in what now are dry and desolate desert wastelands, but were wet and lush during the Ice Age, which followed the Deluge, for very good hydrological reasons (see category Catastrophic Climate Change). And all those civilizations used the same unit of measure as the Egyptians, the royal cubit, this explaining that several ancient cultures were great navigators during the “bronze age,” which also was the Ice Age. See how it was in the free ebook download of my first book, Old Earth? Why Not!, and show that ancient mapping method to your professors, seeing too http://genesisveracityfoundation.com.
