1.The pyramids were originally built to be the tombs of a number of kings, Khufu, Khafra and Menkra. The ancient Pharaonic tradition was that the king's personal possessions and vessels of gold, silver, ornaments should be buried, but also served in the king's cemetery.
2.the pyramids were rich in many historical gold and silver collections that are already owned by the kings of the pyramids Khufu, Khafra and Menqra, but of course they were looted by thieves throughout the ages.
3.The building of the pyramid began in the form of a small hole and then turned into a whole room under the ground and then a group of rooms topped by a balcony and then evolved the shape of the outer pyramid to the pyramid shape or triangle.
