when I say loads it is literally loads.
Right... so you want me to go through all the different parts of Egypt and the variouds Gods they worshoipped until the Kingdom was unified with dfue attention paid to Sumerian infleunce and then track various beleif systems through the ages until the whole mythology collapsed.
Not having a spare day, I won't bother.
Important gods in Egypt eh? Well, Amun was the biggest most of the time. Atum or Aten is actually the creator god and the oldest.
As for the dating of the pyramids, Ush. Trust me. THe Great pyramid is beyond ANY doubt built by Kofu. And give or take two hundred years we can date him pretty well.
If you want to know how certain this is, I'll tell you. The ultimate clue lies in the chambers ABOVE the King's Chamber in the Great Pyramid. The King's Chamber is oblong shaped, which has puzzled Egyptologists for a while. How could a flat roof support those tons of weight above it? Rooms in pyramids when not entirely underground generally have pyramid shaped roofs to get the weight off to the sides.
Now, above the King's Chamber they have discovered over the years a number of chambers above it, five I think. And the top one has a small pyramid shaped like roof. A magnificent piece of work. It is actually in these chambers that the ultimate proof lies for it to be built in the time of Kofu. On the back wall of one of these chambers are quarry marks that continue BEHIND another block. This graffiti mentions none other than Kofu. THat's what I call CLINCHING evidence. This evidence has been accepted by all serious scholars and even by Bauval and Hancock.
If you want to read a very good book about all the so-called mysteries of the Pyramids and the Sphinx and what the real deal is here I suggest this book, came out two years ago: "Giza, the Truth."
