The 30th parallel north appear to have a sacred significance. Holly cities of antiquity on from Egypt to Tibet have been located on it.
It was chosen to be the line on which at the intersection of Ararat – Baalbek line the great pyramid were to be built. And the line that would indicate in the Sinai central plain the cite of the spaceport on the 30th parallel .
This is according to Zakaria Sitchin how the Landing Grid was laid out how the site of the Spaceport was marked off and how the great pyramids of Giza had come into being.
According to Sitchin the pyramids were built not by Pharaohs but by Anunnaki millennia earlier.
There is a known fact although hardly publicized that in 1837 the colonel Howard Vyse and his two assists who had claimed to have discovered within the pyramids that the coffin and the mummified remains s of the Pharaoh Menkara is that neither wooden coffin nor skeleton were authentic . The colonel and his cronies had brought into the pyramid a coffin dating about 2000 years after Menkara had lived and bone from the even later Christian tines, and put two together in an unabashed archeological fraud.
Same colonel in 1837 had “discovered ” a compartments within the great pyramid with the inscription in hieroglyphics of Kufu within a long sealed compartment; and he established the identity of he builder with hat and nobody batter to contest his theory. The discovery was a forgery perpetrated by the founders.
In 1983 a reader of Zakaria Sitchin books came forward to provide with family records showing that his great grand father a master Mason named Humphries Brewer who was engaged by Vyse to help use gunpowder to blast his way inside the pyramid was an eyewitness to the forgery and, having objected to the deed was expelled from the site and forced to leave Egypt altogether.
