Please don't give me they were going to burrie dead kings in them, none of that nonsense, and no alien boff.Is it possible the Egyptians were harnessing the power of the Sun, as they did worship the Sun God, is it possible they mounted large Solar power plates on the pyramid constructions were they produced masses of Electrical Energy, were each household in Egypt had hot running water.   were they not as  stupid .Studies  of the Ancient Egyptians culture through TV documenturies may portraite the Ancient Egyptians as simple farmers, who worshiped the Sun, also dressed up in fancy dress as animals.I mean The Culture was advanced highly. The Pyramids have stood the test of time also they were not short of  steel, the wheel had been invented, as they drove around the streets in chariots also there were loads of sand about, and sand when melted makes glass, which brings me to  the Egyptians could have dabbled with early   Electrical power anyone know any different?
