Fermi paradox proves the existence of aliens. Can humans find them?

So far, humans have not found aliens. According to the probability, there will be more chances to meet aliens in the future than never.

Just say whether there are aliens, the universe is big and all-encompassing. There are known solar system, Milky Way and other galaxies. There are also many different galaxies in that corner of space. As long as there are galaxies similar to the solar system, there may be life and aliens.

The universe is the condition for the existence of matter, which is slowly changing. Tangible matter is always changing. Celestial bodies are of the same law and generation. If there is life in the solar system, then there may be life in a galaxy in space. If there is life, there will be wisdom after a long time, that is, aliens.

According to our understanding of the universe and life, we can infer that there should not be only our earth civilization in the universe, but considering the strong contrast between the history of the universe of 65.438+0.37 billion N and the history of millions of N, we can completely believe that there is a civilization in the universe that is hundreds of millions of N ahead of us.

According to the development speed of our human science and technology, it is easy to infer that advanced civilization is n billion ahead of us, and its scientific and technological level is absolutely beyond our understanding. For this level of civilization, they can move freely in space.

According to this reasoning, the present universe should be very lively, and there are "sightseeing n" of aliens everywhere, but the fact is that we have not seen any confirmation signs of these advanced civilizations at all. The above is the famous Fermi paradox.

In order to explain Fermi paradox, scientists have put forward many hypotheses, one of which is that aliens do exist in the universe, but human civilization is like ants in front of them, and there is no need to invade at all. The reasons are as follows.

The earth is really precious to us human beings. The main reason is that the earth is in a very special environment in the solar system, such as the distance from the sun, the atmosphere that is neither too thick nor too thin, the appropriate magnetic field, Jupiter clearing asteroids for the earth, and the moon stabilizing the earth's inclination angle.
