Is there life on Mars, or has there ever been life? Can you talk about it?

Humans have been exploring Mars for decades, and life will be found so far, but there is no doubt that Mars is likely to become the planet where humans began to colonize. Through these years of exploration of Mars, all scientists were shocked by the sexiness of living on Mars. The gravity of Mars is only 38% of that of the Earth. Although it is very low, it can still make people adapt. At the same time, its soil contains a lot of water resources, which can meet the daily life of human beings. Although it is not certain what substances are contained in these waters, it is speculated that they should be similar to the water on earth. Then there is energy. Because of the charging of solar panels, there is enough sunlight, which can even supply the whole planet. Moreover, Mars also has an atmosphere. Although it is thin, it can also provide some protection against direct damage from solar radiation and cosmic radiation.

So as far as human beings know, no other planet is more suitable for human colonization than Mars. So does it exist on Mars? Life, or did it ever exist? Scientists have also been debating this topic. Because the atmosphere, water resources, geological diversity, magnetic field and other factors are similar to the earth, many scientists have always believed that there is life on Mars, but these lives have long been extinct. They believe that combining all the factors of Mars, it is impossible to give birth to life in billions of years. On the earth with similar conditions to Mars, it will take hundreds of millions of years for life to begin to multiply, but later, I don't know what happened. The atmosphere of Mars is becoming thinner and thinner, which may lead to mass extinction of the world. In the end, all life on Mars disappeared, and with the passage of time, these disappeared lives may be buried deep in the soil of Mars.

At present, scientists generally believe that as long as the surface of Mars can be excavated, there is a great possibility to discover the secrets once hidden on this planet, and some scientists even think that some Mars are. Lights may be hidden in places rich in groundwater resources. 1996, NASA showed samples from Mars, which were said to be rocks formed 4.5 billion years ago. Then, after an asteroid hit Mars millions of years ago, the debris on Mars was smashed into space. It was not until about 13000 years ago that this rock from Mars fell to Antarctica on earth. This rock was discovered by humans in 1984. Through research, they are convinced that this kind of rock does not belong to any corner of the earth. It contains trace amounts of different minerals and carbon compounds, which can only be produced by microorganisms, at least on the earth. With the development of space technology, people know more about Mars. Maybe in a few decades, we can colonize Mars or find life on Mars.
