There are still some other areas that are mysterious.
For example,
The granite coffer in the King's Chamber is too big to fit through the passages and so it must have been put in place during construction. Microscopic analysis of the coffer reveals that it was made with a fixed point drill that used hard jewel bits and a drilling force of 2 tons. The coffer was sawed out of a block of solid granite. This would have required bronze saws 8-9 ft. long set with teeth of sapphires. Hollowing out of the interior would require tubular drills of the same material applied with a tremendous vertical force.
2 tons of drilling force from people who didn't even have the wheel? Seems amazing.
