I've never read it, but having seen one of these answers previously, it reminded me of Siva! by by Leigh & Walt Richmond. Previous title was The Lost Millenium.
The Great Pyramid of Cheops: Geometrical perfection.
The Piri Reis maps: ancient cartographs that show Earth as seen from polar orbit - they have recently been confirmed by satellite photography.
Myriad proofs that Earth has changed its axial tilt during near-historical times: perhaps as recently as 1450 B.C.
In 1962 Walt Richmond developed the theory of the "solar tap": a source of electrical power so great that one installation could provide the world's power. In 1963 his research papers were labeled "Top Secret." The Richmonds refused to work under conditions of secrecy, but Walt worked out on his own the ideal structure for a solar tap.
The Result: an exact replica of the Great Pyramid.
The kind of power postulated by the Richmonds' findings makes all the anomalies of history fall into place. This book was written as science fiction. Whether the story approaches the actual beginning of our civilization is something for each reader to decide for himself...
There is a discussion/critique of the ideas and the book under it's original title, The Lost Millenium here.
It has been suggested as an answers for questions here and here.
There is a book search on Goodreads that is listed as solved with this as the answer. The original description is below.
The premise of the book is that when the earth was all one continent, there was a very technologically advanced civilization that was sending out spacefaring colony ships but had a massive power surge that broke apart pangea. They built all of their structures from stone because metal buildings disrupted their power supply. The spacefarers came back to earth from time to time and tried to re-civilize the survivors which is why there are stone pyramids all around the world (egypt, cambodia, latin america, etc). Also, some people survived the cataclysm on a submarine called an ARK.
