Sorry to tell you Sanat, but your friend Ra is a TOTAL joke, when it comes to the building of the pyramids. Im not sure why you believe all this stuff to be true. Heres a link of PROOF, on how the pyramids were built!

I'll read your others sources, but your friend Ra is a fluke! Ra clearly states in this response, that THEY built the pyramids! These guys are nuts!
III. RA MADE CONTACT WITH EARTH PEOPLES
A. RA WAS AT THE 6TH DIMENSION WHEN EARTH WAS VISITED
RA: I am part of the social memory complex that voyaged outward from a planet in your solar system, the one you call Venus. We are a race old in your measures. When we were at the 6th dimension our physical beings were what you call golden. We were tall and somewhat delicate. The covering of our physical body complex had a golden luster. In this form we decided to come among your peoples. Your peoples were much unlike us in physical appearance. Thus we did not mix well with the population and were obviously other than they. Our visit was relatively short. This was when we built the pyramids.
