They built the pyramids using concrete molds and poured them in place. The Sphinx has been dating g using water erosion to be at least 14,000 - 16,000 years. This being at the end of the last ice age.The pyramids have no hieroglyphics inside and have shafts that were impossible to have "carried simple air". No mummy has ever been found in a pyramid.

These were not built by the people we call Egyptians. They weren't built with manpower and ropes

I like that. Those Egyptians were smart

The Great Pyramid is nothing more then a hoax by the French Freemasons who built them a couple of hundred years ago (1700-1800). They used concrete castings, about as real as Disney Land. Smaller Pyramides might be older, but the big ones are a hoax. Do not take more then one generation to sell a lie.
