What is the scientific basis for the existence of underground civilization when the mysterious entrance is discovered all over the world?

Before the outbreak of World War II, Hitler was drooling over the treasures that might exist underground in the United States and sent expeditions to the United States many times.

Because whoever finds the underground corridors and treasures first will have a steady stream of financial resources, which can have a strong impact on the development of World War II. So Roosevelt sent Ram to look for the "argyle Tower", not only to satisfy the exploration psychology, but also to consider the overall situation of the war.

It is said that the famous German explorer and writer von Daniken once entered the tunnel guarded by Lacantonians.

In the tunnel, he was extremely surprised to see wide and straight passages and glass walls, many exquisite rock gates and gates, smooth roofs and halls with an area of over 20,000 square meters, and many ventilation shafts with an average length of 1.8m to 3. 1m and a width of 80cm appeared at certain intervals.

There are many strange prehistoric relics in the tunnel, including the "golden book" mentioned in ancient legends of many nationalities. The rigor, grandeur and magic beyond the wisdom of modern people in the tunnel stunned this writer who is famous for his bold imagination.

Danny Ken took some photos of the tunnel, but he refused to give more details, only saying that he believed that the tunnel was built with high-tech ultra-high temperature drilling, electron beam directional blasting and some technologies that humans have not yet.

Since the end of the Second World War, there have been more and more investigations on the "argyle Tower" and various new discoveries have become more and more encouraging.

1960 In July, a Peruvian expedition discovered an underground corridor in the Andes 600 kilometers east of Lima. The underground corridor is 1000 km long and leads to Chile and Colombia. However, in order to protect the tunnel and develop it after human beings have mastered enough science and technology, the Peruvian government closed the entrance of this underground tunnel and strictly protected it. This place was later listed as a world cultural heritage by UNESCO.

Therefore, the theory of "underground kingdom", which originated from the underground corridor, triggered a heated debate on the "earth hole theory" in the scientific community. The result remains to be seen. However, it inspired people on the surface of the earth. When the earth's climate changes suddenly or other surface disasters occur, it may be more realistic for people on the surface to go underground than to immigrate to other planets.
