"navel of the world"
from my understanding... all pyramids fall into a line that was fairly easy to document and that there was no room to toss the GP into that line ..
It either has to be the start and others copied it ... or .. it was last and that was the culminantion of all past pyramid construction.
for me there is one enigma which has never been explained to my satisfaction. There is no writting about ANY pyramids with the upward sloping passage. ALL of them have the downward sloping passage.
and there are refrences in the pyramid texts book of the dead about the downward passages.
Until the arabs blow through and discover the upward sloping passages they are never mentioned before that time.... if that aspect was unknown to the egyptions then all the other ones are copies.
you can say that the up ward slopeing passages was a new feature in pyramid building. but that called for a total move away from ALL previous pyramids. totally new design would have been called for not just some minor changes. Like for example the corbeled walls of the grand gallery incorporating them into the pyramid was TOTALLY new and unknown and they hit it EXACTLY right .. the FIRST TIME ... no collapsing ... everything perfect after millenia ... the "air vents" not only are they TOTALLY UNIQUE they also chose THEE HARDEST way to incorporate them into the structure.. once again these features are not even hinted at in texts or other structures.
A third anomoly is the "sargophgus" with the metal straight edge PERFECT lines in all directions ... the way you smooth stone is with something called pecking. you take a small rock HARDER then the stone you are pecking and smash each individual crystal and then with a sanding stone you smooth it.
that is made of diorite ... call up a stone mason in your town .. give him the stats on the coffin and ask how he would cut a rectanglelar block out of a chunk that big and ask what equipment he would need to meet your specifices...
there are unresolved questions about this because there are saw/drill marks on cores that have a twist rate that could only be achieved with the most advanced equipment ..
does they say who built it .. no ... what this says is there are ANOMOLIES that have not been explained to my satisfaction ...
like the stella outside .. kaf with no cartoche .. the graffity above the relieving stone that makes a mistake with Ra - amen ra ..
like I say .. until I see different I will still maintain an open mind on the giza plateau .. and not commit one way or another ...
