Of all the planets, why is Mars the most suitable for human migration?

First of all, Mars is the most similar to Earth. It has a water source and an atmosphere that blocks ultraviolet rays.

1, there is water on Mars, which means that everything can multiply. As we all know, water is regarded as the source of life. If people can't live without water, many lives can be spread for thousands of years because of the existence of water. There is liquid water on Mars, which is an important aspect of human existence. Although the living conditions on Mars are not suitable for the earth, whether there is water on Mars has become the basis for scientists to infer. All this is just a bold speculation by scientists. If humans really want to immigrate to Mars, further investigation is needed.

Mars is similar to the earth, but it also has an atmosphere. According to the pictures taken by the satellite, Mars also has the same atmosphere as the Earth, and the existence of the atmosphere can prevent the ultraviolet rays emitted by the sun from directly illuminating human beings. As we all know, ultraviolet rays can damage people's skin. If you are exposed to the sun for a long time, you may get skin cancer. Imagine how terrible the ultraviolet rays that directly shine on people are if there is no atmospheric shelter. Mars has the same atmosphere as the earth as an umbrella.

Through further exploration of Mars, today's Mars is no longer suitable for human habitation. According to scientists' observation, the atmosphere of Mars was greatly damaged by a celestial collision event, and at the same time, the hot sun shone on the surface of Mars, making the water of Mars turn into steam and disappear into space. So today's Mars is no longer suitable for human habitation, and the earth has become the only choice for human survival. Humans must protect the habitat on which they live. If we continue to destroy it wantonly, we will only meet the fate of mankind with death.

To sum up, although Mars has the conditions to meet human survival, it is a past tense, but it does not rule out that the atmosphere will be completely restored in the future, and Mars will have water again.
