Hi,
If i may add to the Great Pyramid - and any pyramid with same proportions/dimensions creates an energy "vortex" or point of energy being able to charge any object, thing living or not at it's exact center, in the G P corresponding to the chamber of the pharaoh.
Looking at the size and dimension of the G P it is a mini copy of our planet for it fits in its sphere.
Looking at Orion's belt astronomers have concluded that it was built about 10 000 - 16 000 years ago in the age of Leo.
