What is the underground civilization like, and is their level of technology far superior to that of

The technological level of the underground civilization may indeed be better than that of human beings.

The center of the earth is a world of imagination. Compared with space, the exploration of the center of the earth is very difficult. Space and underground exploration are in the same time period, and the result is the difference between heaven and earth.

The space is unknown, and the imagination is beautiful. What is the underground civilization like, let's find out what exploration stories humans have experienced. <>

In 1864, Verne's Journey to the Center of the Earth was published. I may not have expected that my imagination of the center of the earth started a wave of discussion about the center of the earth that lasted for more than a century: swearing, mysteriousness, and serious inferences all appeared at this time.

Before Verne, there was speculation about the center of the earth, and Halley proposed at the end of the 17th century that the earth was composed of multiple hollow spheres, and there were gaps between the spheres, and the voids formed the place where the geocentric people lived. At that time, the focus was on the war between humanity and the civilization of the universe. More than underground, the sky is more of interest.

After Verne, it was discovered that there was also a lot of space for geocentric imagination. Not long after human beings think about the probabilities of the existence of underground civilizations, they begin to have underground civilizations.

Regarding the center of the earth, it is composed of places + exaggerated reasons. If the people in the center of the earth exist, then there is a passage to the center of the earth. Under the blind fabrication of people, there are enough ** for the existence of a few seemingly accurate geocentric people.

In the late nineteenth and early twentieth centuries, at the poles of the earth, there were two entrances to the underground. This is almost impossible to prove, and there are few doubts. Of course, this statement is not credible, and it turns out that there are no holes in the poles, there are only ice. <>

After the invention of the airplane, there was an upgraded version. In 1947, Bird strayed into a mysterious location while flying in the North Pole, and then flew around here and saw civilizations that he had never seen before: flying machines, prehistoric behemoths, and other things.

The people of the mysterious location show civilization to Charlie. After returning, Charlie reported that the content was top secret. There are too many irrationalities in this story.

Compared with the pole mode, the pole tunnel is just "word of mouth", while the corridor tunnel does happen, and whether it can lead to the underground is something else.

The promenade is pointed to the Americas. The civilization of the Americas also points to the legendary Mayan civilization.

It seems to be a pattern: unexplained events, and those are all related to the Maya.

Regarding the underground civilization, people will think of Atlantis, the city is very wonderful, tens of thousands of years ago flying machines have been discovered, and many mysteries are still unexplained, so whether the level of technology is far beyond that of humans, it is not yet possible to achieve the idea.

In fact, there is no underground civilization at all, and this statement is just human imagination. So far, scientists have not found that there is a civilization underground, so this is just imagination or rumors.

There is no underground civilization at all, all this is just the imagination of human beings, and no scientist has discovered the existence of an underground civilization, so it is just a rumor.

Underground civilization is just a conjecture for scientists, and it is not certain that it really exists, so it is impossible to tell whether technology really exists.
