to this post and it’s predessor of “the pyramids is just stacked rocks…”
There are multiple pyramids in Egypt throughout the dynasties but the most famous are the pyramids of Giza which hereunto I’ll just call “the Pyramids.” Others were built but collapsed, succumbed to the desert etc.
*There are only three areas of desert in the world where something as heavy as the Pyramids could have been built. They chose one of them.
*The Pyramids are accurate. They point within .005 inches to North and South.
*Even with cranes, helicopters, tractors and trucks at our disposal, it would be tough to construct the Great Pyramid of Giza today. Its construction 4,500 years ago is so astounding in some people's eyes that they invoke mystical or even alien involvement. But the current theory of the building of the Great Pyramid — the notion that it was assembled from the inside out, via a spiraling internal ramp — is probably still the best construction plan.

This mighty stone formed part of an outer layer of fine white limestone that would have made the sides completely smooth. It was polished until it shone so that the pyramid would have gleamed in the sun. The limestone casing blocks came from quarries at Tura 15km downriver from Giza.

First, let's look at the blueprint: The pyramid is 756 feet long on each side, 481 feet high and composed of 2.3 million stones weighing nearly 3 tons each for a total mass of 6.5 million tons. Legend has it that the structure was erected in just 20 years' time, meaning that a block had to have been moved into place about every 5 minutes of each day and night. That pace would have required the (slave) labor of thousands.
