Just watched this video that delves deep into Ancient Egyptian civilizations. It begins by questioning the accepted story of the pyramids in Giza. The film proposes that the Great Pyramid was used to generate energy (electricity) through light and sound -- not constucted as a tomb for mummies as is widely believed. It touches upon NikolaTesla's work and then traces the cosmology of human history through the ages.
Does human civilization advance with linear time or did Dynastic Egyptians possess superior knowledge to our own about spiritual knowledge and engineering?
