The pyramids are not fake, they are real structures built by the ancient Egyptians thousands of years ago. There are several reasons why the pyramids have been able to remain relatively intact:
1. Building materials: Most of the pyramids were built of solid stone blocks (mainly limestone), which are highly durable and resistant to weathering.
2. Structural design: The structure of the pyramid is very cleverly designed, using a cascade-like architectural form, which allows the pyramid to withstand external pressure and the influence of its own gravity by gradually distributing the weight.
However, some of the problems faced by the pyramids in the last hundred years can be attributed to the following factors:
1. Natural erosion: Although the pyramid is highly resistant to natural forces, natural erosion over a long period of time can still cause damage to it. For example, wind, sandstorms, rainfall, etc., can cause some degree of corrosion on the stones on the surface of the pyramid.
2. Human activity: Over the past hundred years, human activity in the area around the pyramid has increased as the number of tourists has increased and tourism development has boosted. These activities include touching the surface of the pyramid, climbing the pyramid, and urbanization near the building, all of which cause some damage to the pyramid.
To sum up, pyramids are not fake, they are real relics left by ancient civilizations. However, due to the influence of natural and man-made factors, the appearance of the pyramid may have undergone some changes in the last hundred years. It also reminds us to protect these precious cultural heritages so that they can be sustained and witnessed by future generations.
