Life is very difficult to occur on Mars, and even if life is present, it is not too high. The average temperature of Mars in the Archean period of the Earth may have dropped to a few degrees below zero, and Mars was only a few hundred million years old at that time, and the average temperature of Mars was far lower than the average temperature of the Earth during the Huron Ice Age, so it is generally believed that it is difficult for life to appear on Mars, and even if there has been life, it will not be too high. The temperature of the earth in the Particlean period from the extreme average of a few thousand degrees Celsius, to the beginning of the Archean more than 100 degrees Celsius, and during this period the earth's nitrogen also increased wildly, in the middle and late Archean period of the Pongola glaciation period may have been similar to the modern average temperature of the earth, even in the coldest Huron glaciation and the ice period of the two snowball earth periods, the average temperature of the earth will not be lower than the current average temperature of Mars, in the beginning of these three ice ages, The average temperature may drop to even lower, but after a few million years it will rise above -30 degrees, and during the first snowball Earth's Stewart Ice Age, the average temperature may have been in the minus 10 degrees Celsius for tens of millions of years.
Moreover, after the Earth entered the Middle Archean, the average temperature basically did not exceed 30 degrees Celsius, and even during the extremely hot period of the Paleocene Eocene, the average temperature did not exceed 30 degrees Celsius, and the average temperature could only rise immediately after the end of the Huron glaciation or two ice ages. After the birth of eukaryotes about 1.9 billion years ago, the evolution of animals became very slow after the first cessation of iron formation from about 1.8 billion years ago, and the earliest animal evolution branch did not appear until the late Mesoproterozoic, and the first real animal fossils did not appear until the middle and late Neoproterozoic ice Ice, and in this span of about one billion years, the average temperature of Mars may have dropped to more than minus 30 degrees Celsius after its birth. Among the eight planets, except for the Earth, only Venus may give birth to relatively advanced creatures, provided that the birth rhythm of life on Venus is faster than that of Earth, and there is no boring billion-year period like Earth.
All of the above inferences may change in the future because of the following points1The conditions for the birth of higher life developed in accordance with the relevant evolutionary mode of the Earth.2Science is always changing, and a new argument may overturn an old one3
At present, the past average temperature of the Earth and Mars is still not enough, for example, the average temperature of all time periods before the Phanerozoic can only infer what glacial ages may occur before the Phanerozoic, and the past average temperature of the Earth and Mars is simulated by relevant simulation methods, and it cannot be confirmed whether this temperature is the exact temperature at present.
4.At present, most of the geology of the Archean period of the earth is studied on the greenstone belt, but the geology of the Archean and Plutozoic periods is difficult to study thoroughly, and most of the related geology can only rely on speculation, and most of the geological research of the Proterozoic period studies the large igneous rock provinces, and the geological research of the Proterozoic period is more transparent than that of the Pre-Zoic.

Is it possible for life to exist underneath Mars?
-
Scientists wonder if there really is life on Mars.
-
Is the discovery of thigh bones and Morse code on Mars real? It turns out that there are so many secrets on Mars.
-
Mars, of course, is alive. Because scientists have found traces of life on Mars. So there is life on Mars.
-
Life does not exist on Mars. Because there are no conditions for the existence of life on Mars. There is no right temperature, adequate water and oxygen on Mars.
-
It is difficult for terrestrial organisms on Mars to survive, but it is difficult for organisms and life in the earth's environment to survive, and we do not know about other organisms, Mars lacks oxygen for life to survive, there are too many deadly gases, the atmosphere is thin, the radiation is too large, there is no water, and the conditions for the existence of many lives are not available.
-
Because the natural conditions on Mars are too harsh for the survival of the creatures we know.
-
First on Mars. The environment is relatively harsh, and the temperature is very low. It's much cooler than the Earth's, about minus 100 degrees Celsius.
And there's almost no liquid water on Mars. Water is the source of life, and without water there is no way to form life. But this is not absolute, and scientists do not know whether there is anything on Mars or not.
-
The main thing is the lack of a source of life, and it is difficult to have life without water.
-
The question of whether there is life on Mars has never stopped, and Mars has been the goal of many scientists for the rest of their lives. From ancient times, due to people's limited understanding of the universe and the limitations of some scientific and technological conditions at that time, people at that time had an attitude of awe towards Mars, Mars was an ominous thing for people at that time, and human beings never stopped exploring him at that time.
As NASA's research on Mars deepens, humans have begun to discover many clues, and this long-bothering thing seems to have made new progress, with the discovery of organic molecules of life on the Curiosity rover.
Organic molecules are compounds containing carbon elements, and the molecules that make up organic matter are called organic molecules, and more than 30 million kinds of organic substances have been found organically, and their characteristics are even more ever-changing. On the surface of the Gale crater on Mars, after more than a year of drilling, organic molecules including carbon, hydrogen, oxygen and other molecules have been drilled, and these molecules have proved to a certain extent that human beings are right to explore the traces of life on Mars.

In recent years, scientists have confirmed the presence of liquid water on Mars through observation and analysis of Martian surface features, which provides an evidence base for the possible existence of life on Mars. However, whether life really exists on Mars needs to be further judged. Here's how I see it:
1.Liquid water is the primary condition for the existence of life, and Mars has this condition, which greatly increases the possibility of life. However, liquid water itself is not the same as life, which requires many other complex organic molecules and environmental conditions.
Mars needs to meet all of these conditions at the same time for life to exist.
2.No convincing signs of life have been found on Mars. So far, based on the observations of Mars, no indisputable evidence of the existence of life has been found, which does not support the conclusion that there must be life on Mars for the time being.
The existence of life also requires more direct evidence, such as the detection of living organisms and life activities.
3.The environmental conditions on Mars are extremely harsh, which is not conducive to the survival of life. The Martian environment is cold, dry, and radiating, and these conditions are not conducive to the production and reproduction of life.
Although life has a strong ability to adapt, the environmental conditions of Mars are too harsh, and it is still relatively difficult for life to survive and evolve under such conditions.
4.Microorganisms or subterranean life are more likely. If there is life on Mars, it may be some extreme organisms such as microorganisms, or live in the underground environment, which can avoid the harsh conditions on the surface of the star and increase the possibility of survival.
Therefore, the probability of the existence of such life will be greater than that of complex macro-organisms.
5.Sustained and in-depth scientific exploration is required. Confirming the existence of life on Mars requires more in-depth and comprehensive scientific exploration and research in the future.
Collect more direct samples and data from a probe that landed on Mars to find conclusive evidence of life. Only when this evidence is finally found can we conclude that complex life does exist on Mars.
So, in general, the discovery of liquid water on Mars increases the possibility of life on it, but the existence of life still needs to meet more complex conditions. To date, we have not found definitive evidence of life on Mars. The environment is extremely harsh and not conducive to the evolution of life.
If present, microorganisms or subterranean life are more likely. Confirmation of life on Mars will require further scientific exploration and evidence in the future. We can only say that the possibility of life on Mars has increased, but the confirmation of the existence of life needs to be confirmed by further research in the future.

Foreword: Scientists have recently discovered evidence of the existence of liquid water on Mars, which adds more possibilities to the question of whether there is life on Mars. So, to determine that there is liquid water on Mars, do you think there is life on Mars? Let's take a look.
1.There is a suitable environment for life on Mars.
Scientists have found evidence of the presence of liquid water on Mars, indicating the existence of a suitable environment for life on Mars. In addition, Mars also has similar atmospheric pressure and composition to Earth, which means that there may be life forms on Mars that are similar to those on Earth. Therefore, some scientists believe that there may be some microorganisms or other simple life forms on Mars.
2.There is a lack of adequate oxygen and light on Mars.
However, the current environmental conditions on Mars are not very suitable for life compared to Earth. Mars lacks enough oxygen and light, which is essential for complex life forms. In addition, the lower temperatures and intense radiation on Mars also pose a threat to the existence of life.
3.Unknown life forms may exist on Mars.
Although the current environmental conditions on Mars are not suitable for life, scientists believe that there may be unknown life forms on Mars. This is because our knowledge of life is far from enough, and there may be life forms that we cannot currently understand. So, if life does exist on Mars, there may be some novel forms that we have never seen before.
Summary: There is no definitive answer to the question of whether there is liquid water on Mars and whether there is life on Mars. Although there is a suitable environment for life on Mars, there are also many downsides.
In addition, our understanding of life is far from enough, and there may be life forms that we cannot currently understand. Therefore, we need further research and exploration to better understand this problem.
The surface soil of Mars is rich in ferric tetroxide, so it is red in color and visible to the naked eye. >>>More
Some space scientists said that there was a major discovery on Mars recently, which can be described as a leap mutation: on the extremely cold planet of Mars, there is a 20-kilometer-wide underground liquid lake after the feedback information sent by the satellite. This is the first large-scale water source discovered by scientists, and the presence of this subglacial lake on Mars, a proud red star, shows that there is a high probability of life here. >>>More

It's just a rumor. No, no physical evidence – in short, it's like gossip news, gossip news from the scientific community. If there are really alien creatures or something inside, will scientists dare to dissect them? With their advanced technology, they have already pinched the earth to death as an ant......
First of all, let's take a look at the engine structure of German cars, the engine cylinder wall of German cars basically adopts a similar reticulated structure (oil storage structure), the oil storage structure of the engine cylinder wall is obtained through surface treatment, there are many structural forms: straight grain, cracked reticulum, grid reticulation, pits, etc., the German engine cylinder wall is mainly a mesh structure obtained by pine hole chrome plating surface treatment and honing. >>>More
