Do extraterrestrial civilizations exist? Beneath the earth, are there other civilizations? Why?

I don't know yet. Maybe never know. If there is a possibility of life on a planet other than Earth, scientists are basically certain.

The universe is so big that there are countless stars, many of which have an unequal number of planets. Of all the planets, it would be unimaginable to say that only Earth has evolved life. Therefore, it is not impossible that there are planets in the universe with life in addition to the earth.

But it is difficult to say that there are intelligent beings on planets other than Earth that are similar or comparable to human beings on Earth. After all, we only know the conditions for the existence of life on earth, and we cannot know whether it is possible to exist under other conditions, and can evolve intelligent life forms, especially civilizations. Although there are many specious records of so-called "alien" sightings, such as UFOs, they are not certain.

Hawking. It is believed that extraterrestrial civilizations exist, but we do not know the nature of their good and evil for extraterrestrial civilizations, although finding extraterrestrial civilizations may be an opportunity for human development, but it is more likely to be a disaster, which is one of them; The second point is that Hawking has made it clear that he is interested in artificial intelligence and genes.

The worries of superhumans, this is the second one; The third is the concern about sudden changes in the global environment, such as changes in global temperatures.

The universe is so big, and planets like the Earth's environment are also possible, so civilizations outside the Earth are also very likely.

Although it was believed that there was a civilization in the center of the earth in ancient times, today's scientists believe that the earth is a solid sphere that not only has no civilization inside, but is also not suitable for living things. According to the form of **wave, we can understand the general structure of the Earth's interior. The interior of the earth is a hot iron core, which is very hot enough to reach the melting point of iron, but because the pressure here is also high enough, the super high pressure makes iron exist here in the form of a hot solid.

Beyond the iron core, there is a mantle layer, and the mantle layer is able to receive a large amount of high temperature from the earth's core, so that the material here exists in a molten state, and from time to time reaches the earth's surface through weak places in the earth's crust, and this is called a volcanic eruption. Beyond the mantle layer are layers of rock, which are cooler and have many rocks. Outside the rock layer is the earth's crust that we come into contact with on a daily basis, and life activities are mainly carried out in the earth's crust.

The reason why Centroid cannot exist in the interior of the Earth is that the interior of the Earth is not only a solid entity, but also the temperature here is unusually high. Even the temperature of the mantle layer reached a staggering 1000. We know that any substance has a melting point, and a high temperature of 1000 is enough to destroy everything.

For example, when a volcano erupts at a very high temperature, but it is also cooler than the temperature of the mantle, even then, many life on Earth will be killed by the heat released by the volcano in an instant, even if they are not attacked by the volcano head-on.

If there are Centrics living in the interior of the Earth, then the pressure inside the Hola Crater will be higher than that inside the Kora Pit, and it will be difficult for organisms to survive under the ultra-high pressure. Of course, there are also those who would argue that the geocentrics would not necessarily survive in the form of carbon-based life, but might survive in a silicon-based way, that is, silicon-based life. This hypothesis is valid as a conjecture, but in order to be accepted by the scientific community, it must be proven.

Legally, we follow thatWhoever asserts, who adduces evidence; The same is true for the scientific community. For example: I say that I have money, and if I take out the money, it proves that I have money, otherwise it is just a hypothesis.

If people believe that there is silicon-based life in the Earth's interior, then they have to come up with a geocentric life to prove it, otherwise it is just an untested hypothesis, and the probability of its existence is not high from a scientific point of view.

I think there are other civilizations; Because according to the corresponding historical records, before the emergence of human beings, there were various civilizations in the world, and with the gradual change of the times, these civilizations were gradually buried underground and could not be discovered, but I think these civilizations still exist, and they will always be discovered one day in the future.

I think there should be other civilizations, because the earth was actually very prosperous hundreds of millions of years ago, but then there were some accidents, so there will definitely be other civilizations hidden, and we humans have not yet discovered them.

I think there are other civilizations under the earth, because the earth is a very mysterious sphere, and scientists are still investigating this matter, so we must look at it rationally.

There are still other civilizations in the depths of the earth, because after a long history, we can find many things that cannot be explained, and this is other civilizations.

Could there be an unknown civilization inside the Earth? First of all, the USSR really wanted to dig through the earth in order to prove that its scientific prowess was the best in the world. But this decade-long effort is not really giving up, because humanity has yet to make a tool that can dig into the center of the earth.

However, the official reason was a lack of funds, so the work had to be suspended. In fact, the SG-3 was not the only hole drilled by the USSR. The deepest hole is at 12,263 meters and is now an abandoned hole covered with rusty metal caps.

Second, scientists have never set their sights on outer space.

Just as there is a distinct layer of matter in the interior of the earth, scientists have discovered it through the propagation of waves. In 1910, the former Yugoslav scientist Johann Moholovich discovered that local waves refracted as they propagated 50 kilometers above the surface, and a few years later, in 1914, another German scientist, Johann Gutenberg, discovered a boundary 2,900 kilometers below the surface. The Gutenberg and Moho boundary, which divides the Earth into the core and mantle (in the middle) and the crust (the layer closest to the surface of human activity), is now named in honor of the discoveries of these scientists.

Mount Everest, the highest peak on Earth, and the Mariana Trench, the deepest point on Earth, are both located at the very bottom of the Earth's crust, but the crust in the ocean is thinner than the crust of the entire continental region. In addition, it is impossible for anyone who has any concept of the internal structure of the Earth to imagine that there is another human being inside the Earth, let alone the creation of some unknown social civilization.

In fact, the closer you get to the center of the earth, the hotter the environment becomes, which is why the Soviets broke so many drills when trying to dig the earth. Taking the earth's crust as an example, in fact, its material composition is not exactly the same, the upper area is mainly Huanggangshi, and the lower area is basalt, the former is silicon-aluminum oxide, and the latter is silicon-magnesium oxide. Theoretically, the Earth's crust is expected to warm by only 1 degree Celsius for every 100 meters deeper.

But the current drilling results show that the true temperature has risen by degrees Celsius every 100m at a depth of more than three kilometres, so at a depth of 11 kilometres, the true temperature has reached 200 degrees Celsius.

There are legends about these.

One. Gendaya civilization, (superpower civilization) is about 1 meter, men have a third eye, emerald color, and different functions. There are **, lethal and so on...

Women don't have a third eye, so women are afraid of men. But a woman's womb has the power of God, and a woman will contact God in heaven to be reincarnated before she becomes pregnant, and after negotiating, the woman will have a child. This civilization was destroyed on the continent and sank.

Two. The Mesopotasian civilization (food civilization) This civilization is a continuation of the fugitives of the previous civilization. But people have forgotten the past, and their superpowers have been lost.

The man's third eye began to clear. They have a special love for food and have developed a variety of specialists. This civilization was destroyed on the Antarctic continent by the Earth's magnetic pole shift.

Three. The continuation of the fugitives from the previous civilization of the Muria civilization (bioenergy civilization), their ancestors began to notice the energy produced by plants when they germinated, this energy was very huge, and after a century of improvement, they invented a machine that uses plant energy, this machine can amplify the energy, and the civilization was destroyed and sunk on the continent.

Four. The Atlantis civilization (the civilization of light) inherited the previous civilization, and here it is used to inherit, not to continue, because Atlantis came from the colonists of Orion. They possess the power of light.

As early as the Mu civilization, Atlanta was founded. Later, the two civilizations also fought a nuclear war.

Five. The civilization of our existence (the civilization of emotions) uses emotions.

The actual scientific findings may be unclear.

Were there any other prehistoric civilizations on Earth other than human society? The researcher gives the answer.
