Regarding extraterrestrial life, is there extraterrestrial life in the universe?

Although I have heard a lot of rumors, I have not experienced it myself, but I just express some personal thoughts:

Man is alone in the universe, at least in the eyes of man, he is the only intelligent life known in the universe. This led to the search for the same kind. But on the other hand, because of the dominance of the biological chain for a long time, human beings are unwilling to give up their sense of superiority, that is, they do not want other biological species to be able to override them.

This creates a contradiction. People always imagine the form of extraterrestrial life from their own point of view, and limit everything to what they can control, so that people do not feel out of control and panic. But in fact, the way intelligent extraterrestrial life exists could completely upend the current concept of mankind:

They may look like a stone and live by breathing cosmic dust. Therefore, it is futile to find extraterrestrial intelligent life in our own way, and it is only a comfort for human beings.

In addition, it has to be admitted that the appearance and existence of human beings is completely accidental, and the universe itself is an experiment, in which even it does not know what will be produced. As for whether there is a manipulator outside the universe, the question is beyond human imagination. If we think of people as living on a flat surface, then no matter how talented human intelligence is, it is impossible to imagine what it is like to be a manipulator in a three-dimensional space.

Human beings have a natural fear of the unknown and unconsciously protect themselves, which makes them happy to accept what they can see and understand, and reject other things that they cannot understand. Science provides a way for human understanding, but science itself exists within the scope of its understanding, and what goes beyond this scope is labeled "non-scientific".

Therefore, the conclusion is that the universe is rich and colorful, and human beings are extremely small in relation to the universe. Anything is possible, and human understanding is very limited.

Scientists speculate that there is extraterrestrial life in the universe, but so far humans have not found extraterrestrial life on other celestial bodies other than Earth, whether it is lower forms of life or intelligent life.

There is a high probability that extraterrestrial life will exist, because the cosmic environment allows life on earth to exist, and it is entirely possible to allow extraterrestrial life to exist, but human beings have not yet been able to detect it.

Speculation about the birth of extraterrestrial life

There are many reasons to believe that extraterrestrial life exists (even on many different planets). If life on Earth arises spontaneously from a bunch of molecules, through evolution, then life only needs the right planetary conditions, the right raw materials, and a lot of time. The right conditions may include the distance between the planet and its star, so that it is at the right temperature and not scorched by the star.

Suitable raw materials are carbon and water. In any situation, as long as these conditions are in place, give it another billion years, and then the bell will be born.

There are countless stars in the vast universe, and they may also be surrounded by planets, and astronomers have now discovered thousands of them. Some stars even have as many as eight planets, like the Sun. In this way, there may be stars in the universe with more planets than the Sun.

There are at least hundreds of billions of stars in the observable universe, and the number of planets may be even higher. There will always be planets that have an environment similar to Earth's, orbiting in the habitable zone of their star system, with liquid water on the surface, and they have the potential to give birth to life.

Is there any life other than Earth?

To date, no extraterrestrial life has been discovered on other celestial bodies other than Earth, whether in lower forms or in intelligence. However, according to scientific speculation, there is a high probability that extraterrestrial life will exist, because the cosmic environment allows the existence of life on earth, and it is entirely possible to allow extraterrestrial life to exist, but human beings have not yet been able to detect it.

Extended Materials. Astronomers speculate that on planets with completely different environments, completely different forms of life will be born. Life is possible in Titan, the solar system, and perhaps not on water, but on liquid methane.

In addition, life on Earth is carbon-based, and extraterrestrial life may use other elements as the basis for organic matter, such as silicon and germanium, which are in the same group as carbon. It is important to emphasize that life conceived on different planets may have very different forms, and they are most likely not humanoid.

Because the universe is so big, the current astronomical observation technology is not enough for us to directly study the planets outside the solar system, and we have only explored a very small part of the universe, so we have not yet found extraterrestrial life. But with large-aperture astronomical telescopes joining the search, we could discover extraterrestrial life in the next few decades.
