Is it possible that aliens knew about the existence of humans and ran away without wanting to observ

Even if for more than a century, or even longer, scientists have not received strong calls and interactions from extraterrestrial civilizations, but human beings still firmly believe that in this vast universe, there must be no such a lonely exception as our human beings, so why can't human beings find extraterrestrial civilizations?

Almost everyone will think so, alien civilizations are too far away from our earth, and it is very difficult for human beings to find them, or alien civilizations are very powerful, and the level of evolution of their civilization is no longer what we humans can imagine, so think about it in another direction, even if these alien civilizations are very far away from us, even if they are on the edge of the universe, then if the level of alien civilizations is so high, don't they want to look for life in outer space? Or maybe the people of their civilization were not able to reach the current height at the beginning, then in the process of their civilization development, they must be like us humans, they also want to find extraterrestrial life, maybe they have succeeded, or so to speak, extraterrestrial life in their eyes, there is no obstruction!

For example, it is almost impossible for a small ant to discover the existence of an elephant, but at the same time, if the elephant really wants to find this ant, it is not very difficult, although the ant is very small, but in the eyes of the elephant, he is a living creature, and we earthlings are the same in the eyes of alien civilizations, the key is that alien civilizations, whether you want to communicate and communicate with humans, this is the most critical place, We should not think about extraterrestrial civilizations in terms of our civilization level and our vision, which was wrong from the beginning, and the result is naturally wrong!

Do you have any different views on this? Do you think that alien civilizations have already discovered humans, but they just don't want to deal with humans?

No. Because the earth where humans live is very hidden, and there are countless planets in the universe, even if there are aliens, it is difficult to find the existence of human beings.

It's quite possible, but there isn't enough evidence of aliens yet, so everything is on both sides.

The information that aliens have left behind on the earth, scientists say: hidden in the human body!

Could aliens exist? Will humans be explored by aliens?

Lucy's "coffin board" can't be suppressed!

Afan Sihail Australopithecus - Lucy, she lived about 3.2 million years ago.

Fossils excavated have shown that modern Homo sapiens evolved from Australopithecus little by little.

And more than 98% of modern humans and chimpanzees are genetically identical.

But I'm going to digress for now.

Although the subject's idea is detached from reality, it can indeed unearth some interesting topics, such as "throwing low-level creatures to aliens"!

Because some scientists already want to do it!

When I read The Economist last year, I found such a scary article:

<> it is too difficult for humans and other animals and plants to interstellar travel.

Why don't we send some bacteria to another galaxy!

The reasons are: 1. It is easy for bacteria to survive in outer space for many years.

2. After the arrival of bacteria, the environment can be shaped first to welcome the arrival of human beings in the future.

3. Bacteria are very light.

Lightness" is very ideal. In fact, light can bring light pressure, and with light pressure, one can build a very large, very thin, very light "sail" and then accelerate it with a laser. This "light-pressure sailboat" can only carry light things, and bacteria are ideal.

This article also elaborates on a lot of technical difficulties, but there are ideas for overcoming them. If this plan is realized, humans will be able to send microbes from Earth to other galaxies.

Maybe I'm too middle-of-the-second...But I think it's scary to think about it.

Because the origin of life is still a mystery, although the prevailing view is that the conditions of the primitive earth created the organic macromolecules that gave birth to the rudiments of life. But one still can't disprove the hypothesis that life on Earth is extraterrestrial.

Humans have the idea of "sending microbes to the stars". If there were aliens, would they have the same idea? Is it possible that life on Earth originated in an alien spacecraft?

If that's the case, then where are the aliens now? Life on Earth has been around for billions of years, are they still alive?

I think there is a way to stop it, after all, the universe is so big, and it is not very strange that there will be a miracle again. If there is, as long as their technological level reaches a certain level, they will monitor us, so we must work hard to develop our own technology.

Because to other planets, we are aliens, I remember when I was a child, the brain teaser book wrote it hahahahaha.

Because liquid water was found on Mars in space, and it was also found that there were signs of life on Mars. The universe is so big, we have no way to confirm whether there is a planet like Earth, so we humans have always believed in the existence of aliens.

Because the universe is too big, human beings do not believe that there is only one intelligent creature in the entire universe, and there must be other intelligent creatures in the universe, and this creature is aliens.

Part of the reason is that the development of technology has made human beings aware of their own insignificance and inadequacy. The second reason is that there are countless planets in the world, and there are many more planets that are unknown to mankind. As a result, humans will feel that aliens exist.

Do aliens really exist? Scientist: I can't find it, people don't want to see you at all.

Although people have always believed that aliens exist, human beings have been searching for more than half a century, not only have not found aliens on any planet outside the earth, but have never even seen low-level extraterrestrial life, how can human beings dare to be unashamed to believe that extraterrestrial life must exist?

What is that that gives humans this self-confidence? There is no doubt that it must be the breadth and vastness of the universe, even if it is not out of the Milky Way, scientists have found many terrestrial planets, not to mention how many galaxies like the Milky Way exist outside the Milky Way, even if the probability of a planet having life is only, if it is placed in the vast universe, the probability will become above, so extraterrestrial life must exist, but human technology is still relatively backward, and they cannot be found. The technology and civilization of extraterrestrial life may be far ahead of us humans, so why didn't they come to us?

Human beings can ask such a question, which shows that human beings regard themselves too much as the center of the universe, although the earth has long been discovered by extraterrestrial advanced intelligent civilizations, so why do they need to find human beings? Scientists once told the truth that human beings don't need to look for extraterrestrial life at all, because human beings can't find them at all, unless they want to be discovered by humans, then obviously, if they wanted to, they would have already been revealed to human beings!

The time for the development of human civilization is about millions of years, and the time for the high progress of civilization is about 200 years, so obviously, it is not too difficult to find a planet with tens of millions of years of civilization in the universe, but if this civilization is separated by thousands of years from our human civilization, it is almost a gap that human beings cannot cross, how can human beings find them?

For these extraterrestrial advanced intelligent civilizations, low-level civilizations like humans are quite common in the universe, unless they are in need, they will come to find humans, otherwise, it is like a small ant on the earth, dense, each ant is very similar in appearance, and there is no need for human beings to look for one of the ants, what do you think?

does not exist. Because humans have not discovered any aliens, aliens do not exist at all. What doesn't exist, humans naturally can't find.

Not sure, because the current scientific and technological means cannot prove whether aliens exist or not, human beings cannot be found, maybe because science and technology are not developed enough, maybe aliens do not want us to find them, maybe there are no aliens.

Aliens should really exist, because the universe is so big, so it is difficult for humans to find them.
