Some scientists believe that life on Earth originated on other planets. They are based on:

Falling meteorites have found organic matter that can make up life, and even primitive bacteria; There are also elements necessary for the composition of life on a large number of planets.

Summary. In our original understanding, we believed that the earth could give birth to life because it had fresh water, oxygen and other conditions necessary for human survival, and human beings discovered outer space with their inherent cognition, and never found a planet exactly like the earth. Perhaps the birth of living planets in outer space will completely subvert our preconceived notions, they do not have fresh water and oxygen, but they do have life.

There may be life that is completely different from human beings, and all this is waiting for us to explore together.

In addition to the earth, there is life in the universe, and whether there is life on other planets, please use what you have learned today.

What is it used?

You didn't reply to me, I replied as I understood it.

The theory of the origin of life on earth.

5.The chemical origin of the oceans says other planets.

There should be life, and many planets in the solar system alone are the standard for the existence of life, so in the future, if our high-tech development reaches a certain level, it is very likely that everyone will be able to dismantle the secrets of this kind of planet, and then everyone can not only explore life within the scope of the solar system, but also go to planets outside the solar system to explore the existence of life.

Life in the solar system will have some of the same characteristics, such as all carbon-based life, which must inhale oxygen and liquid water, so biologists in the search for life in the solar system rely on the criteria for the production of life on Earth.

Biologists think that the planet with a very high probability is Mars, Mars is on the edge of a beautiful area, it is a rocky planet like the earth, there is a very thin earth's atmosphere, and the earth has a lot of rocky landslides similar to the rent area, after people get rid of the earth, the most explored is Mars.

According to the research, there are traces of rivers on Mars, which shows that in the case of ancient legends, there is also water on Mars, and the probe is still testing the existence of methane gas on Mars, to understand that methane gas is mainly caused by life on Earth, so biologists have high expectations for Mars.

The solar system can be regarded as a planet full of water, the only planet with liquid water on the surface is the earth, but there are many planets whose surface is filled with a lot of ice, for example, many communication satellites of Jupiter and Saturn have a lot of ice on the surface, Jupiter's communication moon Europa is similar to the volume of the moon, the surface is covered by ice, and there is likely to be a huge liquid deep ocean under the thick ice.

There is a high chance that life will be nurtured in the deep ocean, Europa has twice the water of Earth, and Europa is also an ice globe, and it is possible to have liquid deep ocean beneath a thick layer of ice.

Extended materials: Among Jupiter's several communication satellites, biologists are most concerned about Europa, its subglacial deep sea has become one of the main overall goals of biologists to find life outside the earth, Europa also has the imprint of **fountain, there is **fountain indicates that Europa has a very intense geological environment theme activity inside, which is also a very critical criterion for the emergence of life on a planet, and life on Earth can be very closely related to the natural environment.

Saturn also has several communication satellites that also have ice, and one of them has a communication satellite that suffers from the attention of biologists, and its main level is beyond Europa, and even biologists have increased its popularity above Mars, this planet is Ganymede, Titan has a very thick earth's atmosphere, the volume of this satellite is larger than the moon, there is also a very thick earth's atmosphere, and the most important thing is that it has lakes and deep oceans.

It's a norm indeed, because these beings have survived in outer space, and life in outer space is very good.

Life is also the norm on other planets, and although we don't know much about other planets, I believe that there is life on other planets.
