Is life really on Mars? Whether life really exists on Mars

Maybe life existed a long time ago.

Now there is a hypothesis that the "people" on Mars had a nuclear war with each other, as a result of which it led to the destruction of civilization. There was a teardrop under the corner of the man's face.

There is also a hypothesis, that is, at the beginning of the birth of the solar system, there were ten planets (including Pluto at that time), among which there was an unknown planet between Mars and Jupiter (that is, the current asteroid belt), there was a highly developed civilization on it, it seems that Mars was a colonial thing at that time, and then a large asteroid crashed into the solar system, first passing by Neptune when Pluto and Charon reached the far sea point, bringing it into a deeper region, and then knocking Uranus over in one fell swoop, It made its axis of rotation almost perpendicular to the other planets, and then continued to go deeper, shattering Saturn's moons, and then crashing directly into the unknown planet, shattering it and itself together, and the debris fell on the surrounding planets, destroying the civilization of Mars and the age of dinosaurs on Earth.

It is only an assumption, if it is not reliable as an academic basis)

Hope it helps.

It may be there, because there used to be water on Mars.

But it's not likely, those ruins may have been formed naturally, and then very much like signs of life, like things on Huangshan.

Perhaps, some things can only be known to be true or false until they have been experienced, and who knows whether some inferences are true or false, even if there are so-called signs of life, it is not necessarily only living organisms that can have such signs, and the role of physics and chemistry cannot be ruled out.

No, these ruins on Mars are natural objects that resemble cities, pyramids, and human faces.

does not exist. When Spirit and Opportunity went up to the site, they only indicated that there might be signs of glaciation, and through the data transmitted by the two probes, scientists found that Mars had gone through three distinct geological epochs and was now becoming more and more arid. If life ever existed on Mars, life would only survive in its infancy.

As for the Sphinx, those are just mountains on the surface of Mars, craters or something.

It is difficult for Mars to regret rolling out life, and even if there is life, it will not be 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 glacial 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.

1.The conditions for the birth of higher life developed in accordance with the relevant evolutionary mode of the earth.

2.Science is always changing, and a new argument may overturn an old one.

3.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 Qingqing 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-Epoch.

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.

Exist.

In ancient times, there was indeed life on Mars, about 3 billion years ago, the climate of Mars was still relatively suitable, the atmosphere has not disappeared, life can still survive on Mars, and there is still a large amount of liquid water, but life on Mars soon ushered in the end. According to human exploration of Mars, Mars is known to have vast plains, towering extinct volcanoes, and dry riverbeds left by the erosion of ancient rivers. However, the atmosphere on Mars is only 10% dense on Earth, and it contains carbon, nitrogen, argon, and small amounts of oxygen, carbon oxide, and water vapor, making it unsuitable for human habitation.

There is no conclusive evidence that life exists on Mars. However, over the past few decades, scientists have found some evidence that suggests possible signs of life through exploration and research on Mars. For example, water ice and water on Mars are essential for the existence of life, and scientists have found evidence on Mars that may be the presence and flow of water.

In addition, some biomolecular residues have also been found in Martian soil and gas, which may indicate that life once existed on Mars, but these conclusions require further research and confirmation. In recent years, the U.S. Mars rover Perseverance has found some new signs on the Slag Hill planet, which may be chemical markers of protists. However, these findings are still in their preliminary stages and have not yet been further validated.

Therefore, it can be said that although no conclusive evidence of life on Mars has been found yet, through exploration and research on Mars, scientists have more understanding and speculation about the existence of life on Mars, which provides us with motivation and ideas for further in-depth exploration of it.
