Why has water on other planets never been able to give birth to life?

First of all, the subject's question is too absolute, and we can't be sure that only the earth in the solar system has given birth to life in the universe. This is because the universe is so large that it contains countless stars, most of which are surrounded by planets, but our search is very limited. You must know that the Milky Way galaxy has more than 100 billion planets, and less than 4,000 have been discovered so far.

In addition, there are countless galaxies in the vast universe that resemble the Milky Way. Most of the universe has yet to be explored, and we cannot assert that life on Earth is the only one in the universe just because extraterrestrial life has not yet been discovered. In the face of the vastness of the universe, we need to maintain a humble attitude.

Some of the known exoplanets are located in habitable zones, where life is possible. However, at present, our observation technology is relatively backward, and it is not yet possible to determine whether life was also born on those planets. Considering the evolution of life on Earth, and the number of planets in the universe, it is unlikely that we will be alone in the universe.

In addition, some planets have the potential to harbor life on their moons, such as Europa and Titan.

The second problem, as can be seen from the fossil record, that life on Earth can basically be considered to have evolved step by step from Earth, and life, including humans, is the indigenous people of Earth. However, previous studies have pointed out that comets may have brought life to Earth or key materials related to the evolution of life.

As for the last question, there is no evidence that life on Earth was created by a higher ideology. A series of fortuitous processes led to the emergence of life on Earth, where there is no need for a higher ideology.

At present, our observation technology is relatively backward, and it is not possible to determine whether life was also born on those planets.

The growth of life requires not only water but also other materials and conditions, and there may be life on other planets, but we have not yet detected it.

Because they don't have the right environment, they can't give birth to life.

The main reason is that the conditions required to give birth to life are still very high.

It may be that the rest of the earth is not suitable for the formation of life, so it cannot be conceived.

In addition to water, there are some things that must be done, such as air and sunlight.

The main reason is that the living environment there is not suitable for life to conceive and reproduce.

It shows that other planets are simply uninhabitable and incapable of supporting life.

Because the conditions required to give birth to life are too harsh. And maybe life has been born on other planets, but it hasn't been discovered.

Because their other environments do not allow them to exist in a suitable living environment.

Mars is much smaller than Earth and has a much smaller attraction to objects, making it difficult for liquid water on the surface of Mars to exist for long periods of time.

Because the attraction of Mars is very small, the gas does not need to leave Mars too quickly Under the irradiation of the Sun, the water on the surface of Mars evaporates into gas, and these gases gain enough heat to reach the speed at which they can break away from Mars

Because Mars is much smaller than Earth and has much less attraction to objects, water is not retained.

Mars has a fever!! (Hee-hee.......)I guess maybe Mars is too hot, too hot, evaporated?

Under the sun's rays, the water on the surface of Mars evaporates into gases, which quickly gain enough heat to reach a speed that can break away from Mars and never return.

That's what our teacher said, don't believe it! Hehehe! It's so tiring to type!

How can you keep the water on Mars?

Because the planets in the solar system used to be hit by meteorites, the surface temperature was high. Although meteorites and comets can bring in enough water, they evaporate quickly.

However, the fate of the planetary Earth has changed dramatically, and there are very few meteorite impacts. The surface temperature slowly decreases, and finally cools, and the air from the sky forms rain down. The water slowly forms the ocean.

But now, the other planets are not satisfied with the soil, because of the constant collision of meteorites and comets, a little bit of water evaporates, a little bit of water evaporates [including Mars], and there will never be water. It's the same with being human.

Also, I'm a 10-year-old kid.

According to the conditions for the existence of life on earth, the following conditions must be met for the existence of life: an atmosphere of appropriate density, and oxygen is one of the main components of the atmosphere.

1. There is liquid water on the surface, the surface temperature is within 0 100, the distance from the orbiting star is appropriate, and the influence of stellar radiation is small.

Life cannot exist on Mercury for a number of reasons:

1. Mercury is not very massive, and it is the most massive planet in the solar system, only 6% of the mass of the Earth. The mass is too small, so that Mercury has no atmosphere and no oxygen.

2. There is no water on Mercury.

3. Mercury is the closest planet to the Sun, with an average distance of less than 58 million kilometers from the Sun, and the solar radiation is extremely strong.

4. The temperature difference between day and night of Mercury is very large, during the day, the surface temperature of Mercury can reach 427, and at night, the surface temperature will drop to only -173, and the temperature of day and night will reach 600.

To sum up, there can be no life on Mercury. Mercury.

Too close to the sun, too high in temperature, and no water, proteins cannot exist and are not suitable for life to survive.

Life is fragile, and Mars lacks many favorable conditions for the formation and development of life compared to Earth, such as:

1. Magnetic field. The Earth has a strong magnetic field that can deflect solar particle radiation (solar wind) and protect the atmosphere from being blown away; The magnetic field of Mars is very weak and cannot protect its atmosphere, and even if there is a primordial ocean, it has long been blown away by the solar wind, so there is only a very thin atmosphere at present;

2. Temperature. The Earth is in the middle of the habitable zone in the solar system, and the surface temperature is suitable for life. The location of Mars is already on the outer edge of the habitable zone, and the temperature is too low to support the development of life.

3. Gravity. Mars is only half the diameter of the Earth, the mass is only a little more than 10% of the Earth, and the magnetic field is too weak to protect the atmosphere from scattering, etc.

A combination of reasons has led to the harsh natural conditions on the surface of Mars, which are unable to support life.

First of all, the stem of this question is correct, and those who have different opinions can vigorously falsify it, and it is not worth mentioning to speculate and imagine ideologically.

In the context of the empirical discussion, for now, the term means everything. Currently, both conscious and unconscious life exists only on Earth.

If the famous Fermi paradox is not so categorically asserted, then its reasonable explanation should be that there are alien beings in other dimensions. It's just that if the heterodimension does not have any intersection with the three-dimensional world in which we exist, and does not intersect with each other in any way, it is equivalent to non-existence. That is, only the Earth in the solar system gave birth to life.

The life described below is cosmicly unique.

Why is it that only the Earth in the solar system has given birth to life?

Because there are perfect values suitable for the birth and continuation of life, gravitational values, speed of light values, etc., which are incredibly perfect and unreasonable, even if the values deviate even a little, our world will collapse completely in an instant, and the elements that build life itself do not exist.

We use all known and unknown means of observation, no matter how far we will progress in the future, to objectively only prove the uniqueness of life on Earth and the degree of perfection of the current values.

And all this is what we get through observation, and observation is observation under the conscious consciousness, and as long as consciousness exists, there must be purposeful observation.

There is no way to bypass the discussion of the relationship between matter and consciousness here.

Matter is the only and consciousness is the only one. It is only when our only consciousness makes conscious observations of the only substance that matter has the meaning of existence and shows perfection. Without consciousness, nature cannot prove the existence of matter, and it can only be equated with its non-existence.

This argument is that for human consciousness as a whole, it does not apply to individual consciousness, which is unique, but individual consciousness is mutually corroborative. The individual believes that when consciousness is extinguished, the material is dead, and only has metaphysical meaning, and the metaphysical can be falsified by the consciousness of other individuals of the same kind. However, there is no homogeneity to falsify the totality of human consciousness, so the understanding of what we call conscious determinism should go up to the human race as a whole, not to the individual proposers and holders of consciousness determinism.

However, the determinism of who decides who determines matter and consciousness is inappropriate, and it separates the original relationship between matter and consciousness, and their original relationship is a state of yin and yang, which is distinct and inseparable, and is a state of mixed rotation.

From the solar system to the boundless universe, all this exists only to prove that human consciousness has infinite extension, they are only extensions of human consciousness. Otherwise, you can find out the meaning and evidence of their existence outside of human beings and human consciousness, and you can't find it, so we can easily conclude that the infinite universe only exists for the infinite extension of human beings and human consciousness.

All unconscious life on earth is just a dowry brought by human life marrying on earth.

Earth, Sun, Moon, Galaxy, Gravity, Speed of Light, Time, Place, People and ......Everything was designed to perfection so that human beings happily married to earth with a dowry.

Because the ecological environment of the earth is relatively good, it is very suitable for the emergence of life.

Because the survival of life requires many conditions, and only the earth meets this condition, and we have not found any living things on other planets.

Because only the Earth has the conditions for life to be born, such as air and water, and other planets do not, only the Earth in the solar system has given birth to life.

Life is fragile, and Mars lacks many favorable conditions for the formation and development of life compared to Earth, such as:

1. Magnetic field - The earth has a strong magnetic field, which can offset the radiation of solar particles (solar wind) and protect the atmosphere from being blown away; The magnetic field of Mars is very weak and cannot protect its atmosphere, and even if there is a primordial ocean, it has long been blown away by the solar wind, so there is only a very thin atmosphere at present;

2. Temperature - The Earth is in the middle of the habitable zone in the solar system, and the surface temperature is suitable for life; The location of Mars is already on the outer edge of the habitable zone, and the temperature is too low to support the development of life.

3. Gravity - Mars is only half the diameter of the Earth, the mass is only a little more than 10% of the Earth, and the magnetic field is too weak to protect the atmosphere from scattering, etc.

A combination of reasons leads to the poor natural conditions on the surface of Mars, which cannot give birth to life, and because the floor movement of Mars is similar to the crater of the moon, it is no longer suitable for life to survive.

This is not the case with the Earth, where the core is very hot and the surface water cannot penetrate into the ground, so it can give birth to life. The rotation of celestial bodies and the time comes when another celestial body observes our planet and wonders why the Earth and their planetary environment.

Mars is still different from the Earth is no liquid water, which is the most basic and important condition for giving birth to life, organic matter must have a solution if it wants to be fully combined, so some scientists hope to find liquid water in the stratum of Mars, and then see if the water contains microorganisms. As for wanting to have a larger animal or something, you need to have a food chain and an ecological environment, and these are things that Mars can't achieve at present, and humans should be able to transform Mars in the future, and there will be a similar scenario to the Earth at that time.

At the moment, the temperature on Mars is too low for life to survive.

The distance between our earth and the sun is a few kilometers, and it is so hot that it is heat stroke in summer and freezes in winter, not to mention Mars, which is farther away from the sun?

Now the scientist's plan is to make Mars warm up, just like the greenhouse effect on Earth, to pollute its atmosphere.

In addition, the sun has entered its prime, and it may be that Mars will have four seasons in the future.

There's already life, okay?

It's just that it's not yet inhabitable for humans.

I think extraterrestrial life should exist, but we can't find it for the time being, or we will never find it. You think, there are countless planets in the huge universe, how can there be life only on the earth? It's impossible!

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.
