When did humans immigrate to Mars? Can humans survive on Mars?

This classmate. The temperature difference between day and night on Mars is extremely great, reaching 100 degrees Celsius or above. This is one of them. Second, the atmosphere of Mars is more than 90% carbon dioxide, and the rest is nitrogen and other gases. Third, the relative humidity is 100% of the driest time in the Sahara desert, which means it is 100 times higher than that in the Sahara!

Finally, at present, liquid water has not been found on Mars, which is a necessary condition for human survival.

Quote the contents of a certain issue of Science Fiction World magazine: "Humans try their best to transport water to Mars day and night by plane, and the amount of water transported in 100 is not enough for 6 billion people in the world for one day."

At present, human science and technology are very underdeveloped. Although human science and technology have advanced by leaps and bounds in the past 100 years, it is still a long way to go to immigrate to Mars.
