Explanation:  Pyramids are built as tombs for Pharaohs and kings, and as such are a symbol of power and wealth. When burying kings, along with mummified bodies, large amounts of treasure were also stored. The pyramid itself, according to many scientists, is a kind of temple, and in ancient Egypt, the pyramids had a mythological meaning. The pyramid with its physical form represents the path leading to heaven. The base of the pyramid rises from the ground, narrows down to the top and leads to the sun, the deity in ancient Egypt. In this regard, it should be said that the construction of pyramids is perfectly precise and that the geometry and proportions of the pyramid coincide perfectly with the position of the sun and stars at a certain time of the year.
