According to scientific research nowEarth is not the only life form in the entire universeNow many scientists have discovered that there is a scientific proof of the existence of extraterrestrial life in addition to the earth, so the possibility of the existence of extraterrestrial life is accepted by more and more people.

A large part of the reason why people think that there is no life other than the earth is that human science and technology and research progress limit people's cognition.

At that time, people's research technology, especially space research technology, was often limited to the entire solar system, but with the continuous upgrading and development of human science and technology, coupled with the overall progress of human social productivity, more and more scientific proofs have shown that there are other life forms besides the earth.

The existence of extraterrestrial life can now be proven for three main reasons:

First: the area suitable for life in the universe is very vast, that is to say, although the location of the earth in the solar system is very suitable for human habitation, but the universe is very large, and there are many living environments similar to this, so people deduce that there are other life forms outside the earth, but the distance is too far away for human beings to confirm their existence for the time being.

Second: When scientists found many basic elements that make up life on Earth and in the solar system, especially carbon. In the vast universe, carbon is actually found in every corner of the universe, so scientists have deduced that as long as there is a location of carbon, there may be life.

Third, scientists have discovered through telescopes and spaceships that there is also a real existence of ordinary organic molecular elements in the dark interstellar clouds, and this scientific discovery also supports the argument for the existence of extraterrestrial life, so many people, including some scientists, also believe that there are some other life forms besides the earth.

The famous British physicist Stephen. Stephen Hawking, and is also convinced of the existence of extraterrestrial life. Hawking believes that in addition to the earth, there are other life forms in the entire universe, but the degree of science and technology of extraterrestrial life is higher than that of humans on the earth, if human beings take the initiative to get in touch with extraterrestrial life, it may bring extinction to human beings, so Hawking issued a warning to human beings before his death, must not contact the extraterrestrial life, life may bring disasters to human beings, but there are also many optimistic scientists who believe that they should take the initiative to find extraterrestrial life, which can help human scientific and technological progress and development.

Many scientists are now trying to find extraterrestrial life, and it is possible that humans will find extraterrestrial life one day in the future, thus confirming the existence of other intelligent organisms besides the earthBut once an extraterrestrial civilization is found, whether humanity can be prepared is a question that needs urgent consideration at present.

According to the research of American scientists, our galaxy alone is estimated to have 20 billion planets like the Earth (previously said that there are 2 billion, 60 billion, etc., in short, the number is very amazing), these planets have the conditions to support the existence of life, which means that not far from the earth, there may be extraterrestrial life. And billions of extragalactic galaxies as huge as our own have been discovered in the universe! Therefore, it is safe to say that there are countless planets in the universe that are suitable for life!

According to the latest reports, the latest research by Australian scientists says that there may be 200 billion terrestrial planets in the Milky Way, and there may be life on these planets.

There is no information on extraterrestrial life, but we cannot say for sure that there is no extraterrestrial life.

1.According to probability, extraterrestrial life exists.

2.Based on the current level of knowledge and scientific and technological capabilities, no conclusive evidence has been found to prove the existence of extraterrestrial life.

3.When we are unable to solve the famine, war, cancer, and disputes on the earth, there is no need to talk about extraterrestrial life.

The atmosphere of the Earth we live in is rich in oxygen, and it would be difficult for us to survive without it. The latest research suggests that oxygen appeared on Earth 3.5 billion years ago, and that life may have survived to this day.

Because many meteorites have been discovered in recent years, and meteorites contain a large number of organic molecules. It is suggested that there may be life outside the Earth, but there is no conclusive evidence yet.

Water and air are one of the most important substances on the earth, thanks to which life is available on the earth.

The origin and evolution of life are closely related to the origin and evolution of the universe. The constituent elements of life, such as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, etc., are derived from the evolution of the elements after the "big **". The data show that the chemical evolution of the pre-biological stage is not limited to the earth, and the products of chemical evolution exist widely in space.

In interstellar evolution, certain biological monomolecules, such as amino acids, purines, pyrimidines, etc., may be formed in interstellar dust or condensed nebulae, and then biological polymers such as polypeptides and polynucleotides are produced under certain conditions on the planet's surface. Through several transitional forms of pre-biological evolution, the most primitive biological systems were finally formed on Earth, that is, life with primitive cell structures. At this point, the evolution of biology began, and countless complex life forms have been produced on Earth today.

5. Protecting our homeland is no longer an after-dinner gossip, but something that needs to be done in a practical way.

There is no proven answer to this question, let's talk about my personal opinion, first of all, it is certain that there is no life on other planets in the solar system now, but the solid water found at the poles of Mars by the Mars exploration operation may indicate that life existed on Mars before, but there is no definitive evidence.

As for the other galaxies and planets, I believe there is life, but we haven't discovered it yet.

It is difficult to say whether the Earth will be a temporary place for human beings to live, that will be a long time later, but it is certain that the Earth will always be the home of human beings.

Digression: It's very interesting to judge a thing from an objective point of view, take the question you asked about whether there is extraterrestrial life, so far we have not found evidence of the existence of extraterrestrial life, but you can't say no, because if it is found one day, it is existence. The objective world is always presumptive.

I happened to see such a passage in a post bar in Baidu, and it felt quite similar to the meaning of the 1947 Roswell alien interview.

If you come to a place in the universe, the souls of this place are at the bottom of a cosmic creation, they live in a living organism, they forget who they are, where they come from, where they are going, they think that this organism is all their own, they do everything possible to meet the needs of this organism, and they do everything possible to defend and protect their own organisms even if they harm other beings, because they are so persistent in believing that they are this organism, and they never suspect that there are other possibilities. When they leave their organism (death), they still don't want to give up this organism, and the identity, status, fame and fortune that comes with this organism, they still don't doubt their possibilities other than that of an organism, they unconsciously enter another organism, forget everything, start over as a baby, you watch them keep repeating their past like this, keep reincarnating, you observe them like this for millions of years, in these millions of years, You tried all possible ways to help them, to restore their identity as the creator of the universe, but you failed, you once came directly to them from heaven and tried to teach them, but they either worshipped you or feared you, all the teachings were distorted, they could not realize that they and you, and the other creatures of the universe are "one", all are one, all are equal, there is no need to worship anyone, there is no need to fear anyone, you teach them knowledge and technology, As a result, they used the knowledge and technology they learned to destroy themselves, destroy everything they had built, and bring everything back to the starting point and start over. Over these millions of years, all your interference has led to their destruction, again and again, and again and again, and so on, and finally, you learn not to interfere with them, but to just observe them from afar, but to let them develop on their own, to see how they will be, where they will go. Unless their development threatens your safety and the safety of other inhabitants of the universe, do not interfere.

I haven't found it yet, but it's very likely.

Evidence is insufficient and data are lacking.
