What technology and special skills were necessary to build pyramids and ziggurats in ancient egypt?

Simple machines and man power. Egyptians used complex combinations of simple machines such as pulleys and levers to hoist heavy limestone onto each other. Of course, this also required a good deal of physical strength.

Hope I helped!
