Why can the Egyptian pyramids survive to this day?

As one of the seven wonders of ancient times and one of the oldest buildings in the world, the Egyptian pyramids have gone through hardships and vicissitudes in the long river of time and are still well preserved. Look at the other seven wonders, because natural and man-made disasters are either destroyed or incomplete. Why can only the pyramids in Egypt be preserved to this day?

First, because the Egyptian pyramids have a special structure, scientific structure and exquisite craftsmanship, they are not easy to be damaged. The main material of the pyramid is stone, which itself is very hard, and the pyramid technology made of stone is very exquisite. They are spliced together with almost no gaps. Coupled with the special conical structure of the pyramid, we all know that the triangle is the strongest structure in the world. The pyramid takes advantage of the stability of the triangle, and its center of gravity and chassis are particularly stable. 1978 Napoleon once bombarded the pyramids with artillery, but the pyramids remained motionless, and finally Napoleon had no choice but to walk away.

Second, because the Egyptian pyramids are not religious, they are just built as the tombs of the pharaohs and are symbols of human civilization. It is precisely because the pyramids are only graves, and they do not have any symbolic meaning or religious color, so the pyramids will not be destroyed artificially and will remain mysterious forever. All kinds of mysterious legends about the pyramids make people have deep awe of them, and the pyramids are located in the desert, far away from people, and it is difficult to influence them whether it is natural disasters or wars.

Third, Egypt's special geographical position endows the pyramids with a good living environment. Two-thirds of Egypt is desert, where the weather is dry and the pyramids are not easily corroded by rain. Although there are many sandstorms in Egypt, the damage to the pyramids is very limited because of the special square pyramid structure, which reduces the wind.
