What are aliens waiting for? Are there aliens?

I kind of agree with your idea, maybe some aliens want to communicate with aliens like us on Earth (to them), but since they have the same level of technology as us, they can't communicate before they find us. But for the aliens who now have advanced technology and high intelligence, meeting us is like us humans encountering ants or microbes, there is no way to communicate, or there is no need to communicate. Of course, there is no need to contact it.

Even if they come into contact with us, we may not feel it at all. Sometimes we humans see strange phenomena, maybe aliens, but always the dragon sees the end but not the end, maybe that's the reason.

There must be aliens in the universe, because scientists in the United States and many countries have found alien bodies. I think aliens don't know us humans, they don't know if we are benevolent or malicious, and they are afraid that we will hurt them, so they want to fully understand us humans before they come into contact with us.

It's just that they ... They... Some people were contacted, but it is likely that they did not make the matter public for some reason.

I think it's still too far, and those distances are measured in light years.

...Another one who wants to save the peace of the universe.

Go! It's okay to wash clothes and wipe the floor!

I don't think there are aliens who think God didn't create it.

Extraterrestrial life may exist, but technology is not necessarily more advanced than humans.

How do you know that they haven't been in contact with the earthlings?

Are there any aliens? According to the Fermi paradox proposed by the famous Nobel laureate Fermi, if there are aliens, then they may have come to Earth and exist somewhere, but they just didn't communicate with us, maybe our technology is too backward to detect them; Or that there is no other civilization in the universe.

It is the "closest combination" of planets and stars to the Earth and the Sun ever discovered. Kepler-452b is the planet that is most similar to the Earth in shape and external environment, hence the name Earth.

Say the Earth, the Solar System, the Milky Way, what Orion, Ursa Major, this and that, Libra, Aquarius, how vast are these ranges, so vast that you have fresh water on Earth, you have life on Earth, people don't have it, it's unlikely.

It should be broadcast that the universe has detected a mysterious radio wave signal, and people speculate that it may be a signal sent by aliens.

Do aliens really exist?

This issue has been discussed many times, and from a philosophical point of view, it is impossible for there to be a civilization on only one planet in the universe, the earth, and civilization should be widespread in the universe, but the form of civilization is different and the degree is different. Just because we haven't found aliens doesn't mean we don't, it's just that we can't find them with limited technology now, and we will definitely find them in the future.

I think there should be aliens!

At present, there are many cases of alien discovery on Earth, but there is no conclusive evidence about aliens, and I think that the universe is vast and boundless, and there should be aliens and alien creatures

First of all, our universe is very vast. Even if it's the place we humans are currently detecting. There are also more than 100 supernebulae.

There are about 1,000 galaxies like the Milky Way in one supernebula. There are about 10,000 solar system-like galaxies in one Milky Way. It is possible that there is more than one planet in a solar system that has life.

So. Let's do the math.

100 1000 10000 1 = 1 billion. In just the places where we humans have explored, there are a billion planets like Earth that can be inhabited by life. For a variety of reasons, some planets cannot survive.

If you choose one in a hundred, there are also 10 million planets that can always allow life to survive.

I believe that extraterrestrial life exists, after all, the universe is boundless, and since the earth can have life, why can't other planets produce a high degree of civilization!

It is understood that there are 200 billion "brothers and sisters" of the sun in the Milky Way, and scientists have found 150 stars with planets orbiting them, which are distant relatives of the Earth. Even if one of the 10 stars has planets orbiting, then the earth should have 20 billion brothers and sisters in the galaxy, just like only the earth has advanced intelligent life among the nine planets of the sun, then there should be 100,000-150,000 planets suitable for the development of life, and then intelligent life will be produced to form a technological civilization, and they should have a civilization similar to or more advanced than the earth.

So, the possibility of life in outer space is very high. It's just that we don't have a way to understand each other, and we learn from them and think about the same problem. Life in outer space may be more advanced than our science, it may be even more backward, and whether we can find them is unknown.

That's my opinion.

Say the Earth, the Solar System, the Milky Way, what Orion, Ursa Major, this and that, Libra, Aquarius, how vast are these ranges, so vast that you have fresh water on Earth, you have life on Earth, people don't have it, it's unlikely.

Hehe, this question is a bit simple. The universe is so big, the earth is just a speck of dust in the universe, not to mention human beings, and the space outside the earth is boundless, is there only human beings in the entire universe? We are just frogs at the bottom of the well, and maybe there are many birds outside the well.

In addition, for the word "alien", I believe that the first person who says that he sees aliens must be the person who sees aliens with his own eyes, because if there are really no aliens in the world, how can the word "alien" appear? How can there be so many amazing incidents? And how can so many people explore?

So I think there are aliens in the world. [Pure hand-played].

Are there aliens in this world?

Aliens invade Earth and end up falling in love with a woman.

The universe is too vast, there are too many unsolved mysteries, and I personally think there must be.

It seems that there is another galaxy, so there will be other life.

There are aliens, you can see it after watching **10 sets of related programs.

In the vast universe, there should be an answer to your question.
