Were the pyramids built INSIDE OUT? Engineer claims ancient Egyptians built burial chamber first and then worked outwards

Were the pyramids built INSIDE OUT? Engineer claims ancient Egyptians built burial chamber first and then worked outwards | Mail Online: "For centuries it's been thought that the ancient Egyptians built their huge pyramids by hauling heavy granite blocks up specially crafted ramps.



Yet Newport engineer Peter James has branded this ‘impossible’, claiming the ramps would need to have been a quarter of a mile long or else they would have been too steep to carry the large blocks up. He believes, instead, that the Egyptians built an inner core of zigzagging ramps, using smaller, lighter blocks while the larger outer casing stones were placed on the outside using scaffolding."
