There is a possibility of extraterrestrial life in the solar system, but will they be completely dif

It's possible. The existence of life is probabilistic, and what kind of creatures can survive is also uncertain, and the morphological structure may indeed be different.

It is possible that there is extraterrestrial life in the solar system, and they may be completely different from life on Earth. The existence of extraterrestrial life forms may be varied, but just because humans have not discovered them does not mean that they do not exist.

There may be extraterrestrial life in the solar system, and they should be completely different from life on Earth, because their living environment is very different from that of Earth, so life should not and will not be similar.

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, if there is life, it is possible 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 reason why only Earth has life in the solar system:

The distance between the sun and the earth is moderate, so the earth has a temperature suitable for life; The earth has a moderate volume and mass, and has a large amount of silver gas suitable for biological respiration; The formation of the primordial ocean on the earth's feast, with the presence of liquid water; Stable lighting conditions; It has a safe space for orbit operation. Sun Yan.

Life depends on water, air, sunlight, suitable temperatures, and nutrients necessary for life to survive. In the solar system, the Earth is at the right distance from the Sun, so the light and temperature that the Earth receives during the day and at night are suitable for life. In addition, the size and "weight" of the earth are also very suitable for survival.

In the area where the atmosphere and the sea and land come into contact with each other, there are animals, plants, and microorganisms all over the earth, which is the circle of life matter and life activities on the earth, and we call it life. The thickness of life is about 20 km.

In the solar system, there is only life on Earth, and there are no animals, no plants, or no life on the other planets.

Why is there no life on the other planets of the solar system? This starts with the conditions of life's existence.

First of all, the existence of life needs to have the right temperature. If the temperature is too high, the movement of the atoms is too strong and it is difficult to polymerize into molecules; If the temperature is too low, the proteins and nucleic acids will freeze, and life will not matter.

From a temperature point of view, the distance between the Earth and the Sun is unique. The average surface temperature of the Earth is about 22 degrees Celsius, and most of it is suitable for the growth and reproduction of life.

Among the planets of the solar system, the Earth's closest neighbors are Venus and Mars. Venus is closer to the Sun than the Earth, and its surface temperature is about 400 degrees Celsius warmer than that of the Earth; Mars is farther from the Sun than the Earth, and the temperature on the surface is 40 or 50 degrees Celsius lower than that of the Earth, and the temperature difference between day and night is large. The other planets are either closer to the Sun than Venus or farther away from the Sun than Fire, so they do not have the temperature conditions suitable for life.

Secondly, the existence of life requires the presence of liquid water, and there is a large amount of water on the earth, and the vast majority of water is liquid. And on other planets, even if there is water, it is not liquid.

In addition, the existence of life requires an atmosphere of appropriate thickness and density to protect life from cosmic rays and provide the right amount of free oxygen. The Earth's atmosphere fulfills this condition.

Other planets such as Venus, Mars, Jupiter, Uranus, Neptune, and even Saturn's sixth moon have atmospheres, but the atmospheres on these planets or moons are almost oxygen-free, so even if some form of life may occur on these planets, it can only be extremely primitive.

Based on the above analysis, such life on Earth is unique in the solar system.

However, many people believe that in the vast desert universe, there must be celestial bodies with life, and even celestial bodies with highly intelligent life like humans.
