What are the reasons why humans can t discover extraterrestrial civilizations?

In fact, for us, the reason why people have not yet discovered extraterrestrial civilizations may also be because of people's limited technological levelOn the other hand, it may also be because aliens deliberately block the development of human civilization and restrict the process of people's exploration of cosmic civilization. <>

1. The universe is too large, and because of this, it is relatively difficult to seek an extraterrestrial civilization in such a space. In fact, it has to be said that the universe itself is very huge, and it is precisely because of this that it is difficult to seek extraterrestrial civilizations in such a huge space, and it is precisely because it is like looking for a needle in a haystack that it is generally difficult to find extraterrestrial civilizations. <>

2. People's scientific and technological level is limited, and it is precisely because of this that they cannot truly explore the universe, so this is also the most fundamental reason that restricts people from discovering extraterrestrial civilizations. In fact, I have to say that people's scientific and technological level, which is also the fundamental reason why people can't discover extraterrestrial civilizations, because people's technological level has not yet been able to explore the entire universe, and it is precisely because of this that it is impossible to explore extraterrestrial civilizations in the universe. <>

3. The reason why people have not discovered extraterrestrial civilizations may also be because extraterrestrial civilizations have controlled human beings and restricted people's scientific and technological development. In fact, it has to be said that the reason why people have not yet discovered aliens may indeed be because aliens have controlled human beings, and in order to prevent human beings from discovering alien civilizations, they will deliberately avoid human beings, so human beings have not yet discovered alien civilizations.

In fact, it has to be said that the most fundamental reason why human beings have not discovered extraterrestrial civilizations is because people's scientific and technological level is limited, and it is precisely because they cannot truly explore the universe, and the space for exploration is relatively limited, so they naturally cannot discover extraterrestrial civilizations in the depths of the universe.

The Earth is too far away from the alien planet for people to set foot on a planet farther away, or the aliens are deliberately hiding from people to find out.

The reasons are as follows: 1. Humans are still exploring in the solar system and cannot explore further. 2.Human beings judge whether there are creatures on other planets based on their own living conditions, which is relatively limited. 3.Humans cannot receive signals from outside the solar system and cannot communicate with the outside world.

First creation! Thank you for your attention!

The universe is very big, big for us to imagine, and the earth is like a drop of water in the ocean compared to the universe, and when human beings explore outer space, they have not found extraterrestrial civilizations, but scientists still have not given up, because they think that such a large universe has any possibility, since there is life on the earth, then in a corner of the universe, there must be a planet, there is life similar to humans, the earth is not alone in the universe, but we have not yet found our partners, There are a lot of possibilities.

First, Earth's exploration of outer space is limited. The earth only began to develop space technology in the 50s of the last century, although science and technology have been developing rapidly in recent years, but in front of the entire universe, we are still too small, we can not even spy on a corner of the universe, with our current space technology, it is very likely that alien civilizations will not be found, but human beings are still constantly sending signals and receiving radio signals to the outside, hoping to get a response from aliens.

It may be that alien civilizations are ignoring us. The earth has gone through about 100 years of scientific and technological development, and has achieved such amazing achievements, and some of those extraterrestrial civilizations have experienced hundreds of millions of years of development, their science has exceeded our imagination, we are an insignificant ant in front of them, even if they are aware of our existence, they will not give us any response, because we have not yet entered their field of vision.

Earthlings and aliens live at different latitudes. Scientists divide the universe into 11 dimensions, and human beings live in the 3rd dimension, and those extraterrestrial civilizations are likely to live in the 4th or 5th dimension, they can see our every move, but we can't see their corners, just like we watch TV shows on TV, different dimensions perceive differently, so we can't experience the creatures of another dimension, so until now we can't find aliens.

It may be because aliens do not exist, and it is only a human guess, and the universe is also very large, so there will be no alien civilization.

Personally, I don't think it exists at all, it's all fabricated and imagined out of thin air

There are two reasons why you can't find an alien civilization, the alien level is too high, and it can't be observed with the current level of science and technology of human beings, or the level of alien civilization is too low, and it may be just a substance, and there is no civilization of its own, so you can't find it, aliens do have the possibility of existing, but the form is difficult to be the same as our human beings.

Because there have never been extraterrestrial creatures at all, there has never been an extraterrestrial civilization.

It is because the scientific and technological power of human beings is too weak, and we have no way to see many things, or it may be because there is only us in this universe.

If an alien civilization is discovered one day, it is very likely that human beings will cooperate and coexist peacefully with them, enjoy some scientific and technological resources together, and jointly develop some resources.

If one day we humans discover an alien civilization, we can see if this alien civilization will cause some harm to us humans in the future, and if not, we can explore the history of this civilization.

If the way of existence of extraterrestrial civilizations is completely different from that of earthlings, then human beings will find more ways to survive, and human beings will have a new understanding of the universe, thus promoting human beings to continue to progress. If extraterrestrial civilizations exist in the same way as earthlings, then humans can explore why life has developed the way it does.

What would happen if humanity discovered an alien civilization? What will aliens do to humans?
