Is it possible for humans to move to Mars?

Mars and Earth have many similarities. One rotation of the Earth takes 23 hours, 56 minutes and 4 seconds, and one rotation of Mars takes 24 hours and 37 minutes. The Earth's rotation axis has an inclination angle of 66 degrees and 34 minutes with the plane of its orbit, while the inclination of Mars is about 66 degrees and one minute, so Mars and The length of day and night on Earth is similar, and there are also four seasons. What is even more interesting is that in 1877, an Italian astronomer observed many vertical and horizontal black lines on the surface of Mars. People speculated that these were canals dug by Martians. People also observed the surface of Mars. The color changes with the seasons. Some people think that this is the color of the plants on the surface of Mars changing with the seasons. But Mars is a very dry planet. Although there is very little water vapor in its atmosphere, only 1% of the desert areas on Earth. The atmosphere of Mars is very thin, 96% is carbon dioxide, and the oxygen content is very little. The surface temperature of Mars is very low. There is no magnetic field on Mars, and there is no ozone generator in its atmosphere, so it cannot resist ultraviolet rays and various cosmic rays. All these factors indicate that it is difficult for life to exist on Mars. So the possibility of humans migrating to Mars is very slim.
