Have you ever discovered a real so called alien so far?

Of course not, but the American Academy of Sciences announced it 10 years ago"Aliens exist", but they have not been able to produce evidence. However, in recent years, scientists in many countries have discovered extraterrestrial creatures (not aliens) through research, and the American Academy of Sciences has also announced that they have only discovered extraterrestrial creatures.

No, if we don't count ourselves, not even extraterrestrial life has been discovered, only a few planets where extraterrestrial life may exist.

Although no real alien has been discovered so far, I believe that he is real, and it is only a matter of time before he is discovered.

The 1st to 4th floors are not alien lovers, I think there is, anything can happen, don't you think there is? All alien lovers can use their imagination, there are aliens who don't think it's important, what matters is their goals, aliens may have helped humans, but only helped 1 time, like in society, there are good people and outsiders, then aliens are also good and bad, if we can uncover the complete UFO mystery, it means that human beings are great, and it means that we can live in the universe, do you want to just live on this earth? If the earth's resources are gone, human beings will die.

No, I don't. Now what the so-called ** about aliens is fake.

No, UFOs can be explained by the earth and science Watch more CCTV10

I am. But I've been self-promoting and no one has come"Discover"I.

There's a good chance there's a secret dossier!

There is currently no clear evidence that aliens exist, and aliens can now only be classified as hypothetical as humans.

Astronomers are constantly discovering new planets in the distant solar system. Some believe that the existence of so many planets proves that there must be life elsewhere in the universe. The truth is that none of these have proven to be any near-life-habitable planets.

The enormous distance between Earth and these planets makes it impossible to make any judgment about their ability to sustain life.

Perhaps only Earth supports life in our solar system, so evolutionists are very keen to find another planet in another solar system to support the idea that life must evolve. There are many other planets on Earth, but we don't know enough about them to confirm whether they can sustain life.

Scholarly perspectives

Astrophysicists at Harvard University theorized that it was almost impossible for humans to discover the existence of extraterrestrial life. Even if there are several clues, it can be difficult to establish a connection with them. According to this inference, there may not be any so-called aliens at all, and human beings are truly outstanding in the vast universe.

To date, astronomers have discovered a total of 500 planets from distant galaxies known as exosystems (and similar in structure to the solar system), and believe this is just a drop in the bucket of hundreds of millions of similar stars. Based on this assertion, many scholars are positively optimistic about the existence of extraterrestrial life.

At present, humans cannot actually detect the existence of aliens.

There have always been reveries about aliens in ancient and modern times, but now human beings have not been able to actually detect the existence of aliens, although many people have always claimed to have witnessed aliens visiting the earth and even having contact with themselves.

However, most scholars and experts believe that the so-called different degrees of contact between human beings and aliens are actually psychological effects, and the chances of human beings discovering "aliens" are very small, and even if they are found to have aliens, it is almost impossible to have any contact with them.

Alien birth conditions:

As we have seen, the birth of intelligent life requires that stars must be able to emit light and heat stably for at least about 5 billion years. The lifetime of a star is closely related to the size of its mass. The thermonuclear reaction of massive stars can only last for a few million years, which is far from enough for the evolution of life.

Only stars of similar solar mass are suitable candidates, and there are about 100 billion such stars in the Milky Way, and about 40 billion for a single star except for binary stars. Does a single star have planets? Unfortunately, we know very little about other planetary systems, but observations have gradually led to the presence of planets around some stars.

Considering the objective existence of the solar system, even large planets have their own satellite systems, such as Jupiter in the solar system. It is possible to optimistically assume that all single stars have planets. The existence of planets does not mean that there is life, let alone the existence of higher beings.

The key is that the distance between the planet and the parent star must be just right, not far or near.

The above content reference:

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.

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.

Are there really aliens in the universe?

I guess aliens exist! Think about it, there are countless planets in the huge universe, how can there be life only on the earth? It's just that with our current level of technology, we can't find extraterrestrial life.

But planets like our Earth with highly developed intelligent beings like humans may be just a handful! Because for a planet to evolve into advanced intelligent beings like us humans, it needs a long period of stability on the planet without destruction and cataclysm, and it just so happens that our earth has such conditions! It can be said that this is a great deal of chance!

Therefore, the proportion of planets with highly developed intelligent beings in the universe is not very high, and the huge distance between the universe has become an insurmountable obstacle to the interconnection of intelligent beings, so even if there are aliens, it is difficult for us to find out! I am pessimistic about this, and I believe that human beings may only be able to exist alone in the universe until the end comes!

In addition, the sun on which we live is nothing more than a very ordinary star, and there are countless stars in the universe! According to the latest research by American scientists, there may be 60 billion habitable terrestrial planets in the Milky Way galaxy where the Earth is located, and these planets have conditions that support the existence of life, which means that there may be extraterrestrial life not far from the Earth. Therefore, it is safe to say that there are countless planets in the universe that are suitable for human survival!

So far, there is no reliable evidence that aliens have ever been to our planet!

Again, aliens exist, but the vast distance of space in light years has become an insurmountable obstacle to the interconnection of intelligent beings. You can imagine that even the speed of light of 300,000 kilometers per second would have to travel for years, decades, hundreds, tens of millions of years, or even longer! What an unimaginably long distance!

Therefore, it is simply impossible for the so-called aliens to visit or invade the earth! Constrained by the laws of physics, I don't believe that intelligent beings can build spacecraft that can fly at the speed of light, it's all science fantasy, how can it be so easy? Therefore, it is not credible.

Do aliens really exist in the world?

There are many planets with life in the universe, but there are less than 2 planets with similar intelligence to human beings, one is the Earth, and the other is a planet in an extragalactic galaxy, which is far away from the Earth.

The authenticity of UFOs is not known, but I think there must be extraterrestrial beings beyond Earth! Some bricks say that there is no water and no oxygen on a certain star, and there must be no aliens. I wondered, can alien creatures be like terrestrial creatures?

Don't take the living conditions of human beings to set alien creatures They are different from us, just like deep-sea creatures with so much pressure No light and ultra-low temperature They survive the same environment that humans can't adapt to doesn't mean that alien creatures can't adapt to it Not to mention that the universe is so big So I think there must be!

There must be because they are right behind the moon.

Existence, like a cow, a ghost, a snake god, dominates humans.

Definitely exists. We may be the alien species.

It should exist, the universe is so big.

If you feel there is, you exist.

exists, but is not a very complex living organism.

I don't believe in intelligent creatures, there may not be many, but there are definitely living things.

The evolution of higher intelligent organisms takes about 4 billion to 5 billion years (relatively advanced single-celled organisms began to appear on Earth about 3.5 billion years ago); Secondly, during this time, the state of the planets and the parent star should be very stable and cannot be destroyed; Third, the planet should not be too close or too far from the star, and should have the conditions for the presence of liquid water; Fourth, the star is of moderate mass and in its prime (like the Sun). If all these conditions are met, we must also see that this is only the most basic. If there is life on this planet, has this life evolved to the level of civilization comparable to that of our human beings?

If they are lower than us, then it is unrealistic to find them at the moment. Scientists have speculated on how many planets in the Milky Way have advanced life, ranging from a few thousand to one or two, but one thing is the same: this possibility is too small.

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.

The universe is so big that it should not be exclusive to life on our earth, so scientists have always believed that there are aliens. But so far, no trace of aliens has been found, and scientists are still searching for them, hoping to find them one day and pay tribute to them.

Human beings have not discovered any extraterrestrial life so far, and there are two views on whether there is extraterrestrial life, and my personal opinion is biased towards the existence of extraterrestrial life or even civilization in the universe, but I do not believe in the so-called flying saucers or aliens that appear on the earth.

The universe has been developing for 100 million years now, the age of the solar system is about 5 billion years, and the age of the earth is about 4.6 billion years. Even if there is a star formed a billion years earlier than the sun, and a planet formed a billion years earlier than the earth, then from the perspective of time, it is enough for life to develop and reproduce, and if there is a civilization, it is likely to be higher than ours.

There are hundreds of billions of stars in the Milky Way galaxy alone, and our Sun is just one of them. If you are statistically speaking, it is almost impossible to see that only life is produced on Earth, and the other planets in the universe are barren.

The generation of life will go through the process of starting from nothing, and it depends on the environment for a creature to evolve and develop civilization in a more intelligent direction. After all, the dinosaurs that ruled the earth for almost 200 million years did not evolve civilization, and human beings developed civilization for three to five million years at the earliest.

But if there are aliens, why haven't they come to Earth so far? This is the Fermi paradox! Of course, it is also possible that human beings will not see extraterrestrial life until the end of civilization, which also has a huge relationship with the scale of the universe.

At least flying out of the home galaxy is very difficult.

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.
