First: The pyramids are the tombs of Egyptian kings.
In fact, from the pyramids that have been developed now, we can know that many Egyptian kings, queens and pharaohs are buried inside, and they are all important people in Egypt. This shows that the pyramids are the tombs of ancient Egyptian kings. Many Egyptian kings began to prepare their graves when they first ascended the throne, because ancient Egypt, like the ancient kings of China, believed in power and status.
Even after the death of these kings, they still hope that they can get high courtesy and luxurious residence. Because tombs are very important to pharaohs and kings in ancient Egypt, you can also leave your own tombs for future generations to sacrifice. So in ancient Egypt, the more powerful people were, the greater the height and scale of the pyramids they could have.
Second: The pyramids are places of sacrifice.
In fact, the ancient Egyptians, like the kings of China, believed in destiny. In ancient China, there were often rituals of offering sacrifices to heaven and ancestors, and so did ancient Egypt. These pyramids are places of worship. But not all pyramids can be used for sacrifice. If pharaohs or rulers have been buried in the pyramids, they can't be used for sacrifice.
Unless it is the pyramid of ancient Egyptian ancestors, it can be used as a sacrifice for future generations. On the day of sacrifice, the Egyptian people will appear in front of the pyramids, sincerely bow down and pray for the blessings of their ancestors for future generations. Sacrificial activities can generally only be carried out on important days.
Third: used as a palace.
In fact, when the king of ancient Egypt was still in power, he still needed a place to meet his own people, and the pyramids could be used as palaces. So in fact, the Egyptian pyramids are equivalent to the Forbidden City in China, which is a place where saints are faced.
