The universe is so big, are there aliens?

There may be aliens, but after so many years of searching, there is still no news of them, I think there must be none, in fact, there are many hundreds of millions of light years away, and it is impossible for us to meet.

Personally, I think that there are no aliens, and if there are aliens, they will definitely explore our earth, but with our current scientific development, we have not found these conditions, so there should be none.

Hearing is false, seeing is believing, and according to the current understanding of human beings, aliens definitely do not exist. If it existed, we would have communicated and communicated with him a long time ago.

Absolutely. But not easy to find.

Far from it. In our galaxy alone, there are more than 200 billion stars like the Sun. They carry countless planets.

It's hard to believe that there is nothing suitable for biological growth. And now it is found that the adaptability of life is far wider than originally recognized. Organisms have been found to be able to survive in an environment completely devoid of water.

Therefore, it can be assumed that there is life on not only other planets in the universe. And there should be no less. Of course, it is possible for life to develop into intelligent life, that is, "aliens".

That being said. But it's not easy to find them. Because celestial bodies are far away from each other.

There are only a handful of them that are tens of light-years away. The odds of having aliens there are very small. Others are hundreds of thousands of light-years away.

In this way, it takes twice as long to go back and forth with an airwave signal. And the universe is full of all kinds of cluttered radio signals. It's hard to sift through artificial signals.

So it's not easy to find them.

With the scientific knowledge we have at the moment, it is very difficult to communicate with them. But the science and technology that people have mastered may be much more advanced than ours. It's hard to say that they can come and contact us.

But I'm afraid it's not a good thing. Because the wisdom gap is too big. In their eyes, we are like lower beings.

This can be a nightmare for humanity.

The universe is 13.7 billion light-years large, and it is still unclear whether there are aliens! No scientist can say for sure whether there are aliens or not.

The universe is vast, at least for now! Perhaps our current understanding of the universe is the same as the ancients' understanding of the earth. But who's to say that?

Aliens can't say that there are, because there is no evidence that aliens do exist, but there are no absolutes in everything, and it can't be proved that there is, but it can't be said that there is no 100%, but this kind of thing is very illusory, believe it, and don't believe it, don't spend too much time!

Are there really aliens? It's still a mystery! Although there is no definite evidence yet, I believe that there must be other life in the vast universe!

I'm not guessing! The universe is so big that there are no surprises! Although it takes a lot of conditions to give birth to life, it is not impossible, and the earth is an example. There are countless planets like the Earth in the universe, is it only the Earth that has life?

Even if all life needs water, there is more than one planet with water. At present, there are only no planets with liquid water in the solar system, and there are many galaxies the size of the Milky Way in the universe, and there are countless ones that look like the solar system! Are you afraid that you won't be able to find a second Earth?

Although we can't find aliens yet, won't aliens with more advanced technology than us look for us? So far, there have been many things that resemble extraterrestrial spacecraft, collectively known as UFOs, and although 99% of UFOs are masterpieces of nature, aren't there still unproven ones? Aren't they alien spaceships?

To sum up, extraterrestrial life is definitely there! It's just not discovered.

A few days ago, some scientists said that they had calculated that the planets and star systems in the Milky Way galaxy are similar to the Earth-Sun. According to research, there are about 1% of stars of the same type as the Sun in the Milky Way, and at least 10% of them have planets, that is, 100 million stars like the Sun have planets.

So the future will definitely be discovered.

Absolutely.

There is life on Earth, why can't there be extraterrestrials!

And many scientists have also done experiments to try to kill bacteria on the earth, but they can't kill them completely. Without oxygen and water, some of the bacteria survived and began to mutate!

Yes, if you think about it, the earth is just a small grain of sand in the vast universe, and since there are earthlings, there will also be aliens. If you dare to be interested in UFO video clips, I will introduce you to **, which includes a lot of UFO videos from all over the world.

Although scientists believe that even if there are aliens, it is impossible to fly to Earth because of the huge distance between the planets, they do not deny the possibility of intelligent life in outer space.

Whether extraterrestrial beings exist.

UFOs exist in mysterious ways, and tens of millions of earthlings claim to have seen UFOs. Are these "witnesses" fantasists or **? Or is there something between a lie and a truth?

Is the answer on a planet in space, or is it from humanity's cult of mystery?

The first boom in UFO research in the world began with the most famous "Arnold event" in the history of UFO research. UFO is an English abbreviation that means "unidentified flying object", also known as "flying saucer" or "UFO", which refers to a moving flying object or astronomical spectacle that can be observed by the naked eye or radar, and which is currently unexplained by humans. People who are interested in UFOs not only speculate that this is from a civilization that is more advanced than the earth, but also explain this phenomenon with psychological inferences about the problems that modern people may face.

UFOs are described as: moving or circling rapidly; Silent, erratic, or unusually roaring when moving; Shapes such as saucers, cigars, sphericals, rings or ovals have been counted in more than 100 different forms.
