Forget what you learned in High School in your geography class regarding the Egyptian Pyramids. What did you and I learn in High School? Pyramids were built for the pharos (kings & queen) by using slaves, copper tools, and pulleys that helped drag these 10-30 tons granite and limestone rocks. (In Japan they did an experiment to do just that, and even 100 people couldn't pull a ten ton block more than twenty feet, before they all gave out.
