The "how" will have to be answered first because it is the only question that can be explored by modern science without having the answers to the other questions.

This is the question that scares the bejeebers out of Egyptologists. They're well aware they created a whole science based on stinky footed bumpkins dragging stones and they are afraid to test it. They are afraid of the pyramid because understanding the pyramid is the firest step to understanding the people.

We need engineers and scientists in charge who aren't afraid of the pyramid.
