Pyramids are distributed in Egypt and the Americas, including upper Egypt, middle Egypt and lower Egypt in ancient Egypt, present-day Sudan and Egypt. The current lower reaches of the Nile are about 80 Pyramid ruins.
Egypt found 96 Pyramid, the largest of which is the three Pyramid of Hufu in Cairo suburb.
Since about 3500 BC, dozens of small slavery countries have appeared on both sides of the Nile. In about 3100 BC, a unified ancient Egyptian state was established. The king of ancient Egypt, also known as Pharaoh, was the largest slave owner in ancient Egypt and possessed supreme power. They are regarded as the incarnation of God. They built a huge mausoleum for themselves. Pyramid became a symbol of Pharaoh's power in Pyramid. Because these huge mausoleums resemble the Chinese character "gold", we call them "pyramids". Before the city of Pyramid, there was a Sphinx guarding the tombs of pharaohs.
