If there were aliens, would they know we were here?

We already know that there are countless planets like our Earth in the vast universe, and scientists have explored that there are no planets suitable for life in our solar system. I don't know if it's a technical problem or a fact, the [solar system], which is very close to our solar system, can't find life, and the nearest planet with life is 20 light-years away from us, and we can't travel there at all, and it has been confirmed that there is intelligent life on that planet. We can't even fly out of the solar system, and some scientists say that when we fly out of the solar system, it will be completely dark around us.

It is clear that the solar system is our cage, and the cosmic space we see may be distorted and overlapped. Aliens may also have this dilemma, unable to access and confirm their findings. If we look at the vast universe, our galaxy is too small to see, who will see our solar system and the small earth?

Even if we discover and guess that there is life on those planets, we can't confirm it at all, knowing or not knowing, aliens really exist, they can't run away when they discover and know our earth, doesn't it mean that they don't know that we are here?

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 it will definitely be found in the future;

Concept 1: The multi-dimensional world is like ants can't see humans, because ants can only feel two-dimensional space, while we humans are in three-dimensional space, just like the ending of Men in Black III, it is possible that we are just living in a corner of the wardrobe in the universe.

Concept 2: The theory of life, the existence of life itself is a miracle, so it requires harsh conditions, because of this, under the current scientific and technological capabilities, there has not been a public announcement of the discovery of extraterrestrial life on the planet, but I believe that no matter how low the probability is, then there is a chance to exist, and human beings are the best proof.

This is a relatively mainstream speculation at present, and some also speculate that there are higher intelligent life forms in the center of the earth, and so on.

When it comes to aliens, of course, this is a non-committal question, but, as far as various scientific detectors and archaeological evidence are concerned, aliens should exist. In the past, "Mystery" magazine often published explanations of aliens**, and there are many individuals abroad** who claim to have seen aliens, but here I want to explain that crooked nuts usually like to magnify a thing and create a sense of surprise and mystery, which can also explain why people often see so-called wild people in Changbai Mountain, but it is just a gimmick blinded by speculation.

However, as for the existence of aliens, almost all scientists in the world are in the same voice, exist!

The Milky Way is very large, people have not explored it completely, the metaverse is even more vast, and the earth is just a small planet. Aliens may live in other galaxies, or they may live in outer space, so humans can't find them. Mainly due to the limitations of science and technology, if human beings invent space-time jump technology or space compression technology, or spaceships, they can also travel through the universe, and maybe they can find traces of alien life.

There are a lot of aliens in film and television dramas, and these aliens look strange, although they look more like people, but they are very weird, such as eyes that are very big or have no ears or wear strange costumes. These aliens are not real at all, they are imaginary by humans. Because human beings have not found the real trace of aliens at all, they can only speculate based on what they already have.

I have also seen a lot of interstellar or science fiction**, which also describes the life of people in the interstellar era, for example, you don't need to cook by yourself at all, you only need to drink nutrient solution, and you can take a flying car when you go out. Another example is that the universe is a very large country, which may be composed of countless planets, and is collectively called a federal state. These are all artificially written, and we don't know that the real aliens are in **.

At present, human beings have not even completed the exploration of the earth, for example, they do not know what is in the deep mountains, and they do not know what is in the deep sea. Although there is manned space technology, there is no way for human beings to wear thick clothes to live freely in space, and this technology cannot be popularized by science. However, people are very smart, and they have the gene of not admitting defeat in their bones, and they will definitely continue to study aerospace technology, and they will also have different achievements in space exploration.

These things are very far from the lives of ordinary people, people only need to worry about what to eat today or whether they can find a job, and such a significant thing needs to be handed over to someone who has the ability, such as a scientist.

The alien should be on some planet in the universe. Because the universe is vast and beyond the scope of human exploration, they cannot be found.

I think that if there were aliens, they might also live in the wilderness, or hide themselves completely and be trapped in the middle of the world; The main reason why we can't find these aliens may be because these aliens are very well disguised, which makes it impossible for ordinary people to tell the difference.

They must not be on Earth. It could be hundreds of millions of light-years away from Earth. So we can't detect it with our current technology.

They live in places we don't know, and they're all very mysterious, so we can't find them.

I believe in the existence of aliens. Because the distance between each starry sky is very far, the chance of aliens coming to Earth is very small, so everyone has never seen it.

Believe; Even if there are aliens, they should be very far away from the earth, and they may not be able to reach it.

There are no aliens in the universe, and all aliens are made up by science and technology, and they are a conjecture formed by the forces of the universe.

So far, there has not been a single extraterrestrial event that has been confirmed and accepted by scientists. That is to say, so far there is no evidence, not even evidence, not a single object left by aliens has been found on Earth. So far, there have been no aliens on Earth.

1. It is possible for aliens outside the Earth or for earthlings to become aliens on other stars. Because the universe is so big, it is impossible for there to be life on the earth alone, there must be other planets where there is life school, but we have not discovered it yet.

And the earthlings have already landed on the moon, and at that time these astronauts have become aliens on the moon, so there are aliens in the universe.

2. It is certain that there are human beings who have landed on other stars to talk about envy, because at this time these people have become aliens on this astral body. And no one can solve the problem of whether there are aliens in the universe other than the earth.

3. What is certain is that there is no conclusive evidence that aliens have ever visited Earth. It is not uncommon for some people to refer to natural phenomena that cannot be explained by science today as extraterrestrial visits (UFOs). And a lot of the time what they see is actually an artificial aerial vehicle.

There are also some people who say that the ancient civilization of mankind is an alien civilization, and attribute everything that cannot be explained now to the masterpiece of aliens, which is an insult to mankind itself!

In fact, human creativity is very strong, and what we can't do now doesn't mean that ancient humans can't do it. Don't say anything is alien.

4. UFO refers to unidentified flying objects, which generally refers to all non-man-made flying objects. UFOs must be there, and there are many things that humans can't explain. But whether it is related to aliens is unknown.

By saying this, I do not deny the existence of extraterrestrial civilizations in this world, on the contrary, I agree with the existence of extraterrestrial civilizations.

However, in favor of the existence of extraterrestrial civilizations, it cannot be said that we agree that human beings have discovered extraterrestrial civilizations, let alone that extraterrestrial civilizations have been to the earth. I am a more rigorous person, and everything is subordinated to evidence.

Conjecture can only be used as conjecture, it can be science fiction and fantasy, but it cannot be affirmed as evidence.

The reason why I think that there should be extraterrestrial civilizations in this universe is because this universe is too vast, and there are countless planets with environments like the earth, and extraterrestrial civilizations do not have to be like the earth civilization, and various environments may give birth to different civilizations.

However, due to the distance and the different types of civilizations, it is difficult for these civilizations to meet together, and it is even more difficult to achieve communication. The way of existence and form of these civilizations, as well as the way they perceive the world, may be very different from that of human beings, making it difficult for them to encounter and communicate together.

Gamma-ray bursts are generated by massive celestial collisions or supernova explosions, and this powerful energy burst will periodically or irregularly empty the civilization of our universe, which makes it rare for civilization to rise to an advanced stage.

Only advanced civilizations can carry out interstellar voyages, and it is possible to reach distances light years away.

In a state of civilization like our earth, it is still an unattainable luxury for ordinary people to reach the moon, and the moon is only a little more than 1 light second away from us.

It takes more than 17,000 years for unmanned probes to fly out of the solar system, and at such a level of civilization, human beings cannot leave their home planet, let alone reach other planets, or even fly out of the solar system.

Extraterrestrial civilizations cannot come to Earth if they are only at the human level.

The vastness and sparseness of the starry sky is beyond imagination, and the distance between the stars is more than a few light-years, which is equivalent to two coins in a range of more than 1,000 kilometers, and the probability of colliding together is too small and too small.

And with so much energy and time, why did they come to Earth?

Different civilizations have different needs, and our earth has air and water, and it is not necessary for everyone to need it. Moreover, if human beings on Earth have the ability to travel interstellarly, they may not go to a distant planet for the sake of air and water.

If humans had that ability, it would be more than enough to transform the solar system or a nearby planet.

The greatest resource in the universe is energy, and what high-level civilizations need is energy, and energy is everywhere.

The story of aliens who invade the earth at every turn for the sake of the earth's resources in science fiction movies and television is completely illogical nonsense. It can only be a pastime, not a serious one.

So, I said that aliens will not come to Earth.

Aliens can detect our existence, because aliens still have very developed technology and can detect our human existence.

It may be detected, because there are countless planets in the universe, and the existence of advanced life is entirely possible, and there may be countless aliens that are more powerful than we imagined, and the powerful scientific and technological power will make it possible for them to detect.
