The sun is expanding. Is there any hope for human migration to Mars?

As the name implies, there is no hope at all. Although we are all saying that the earth and Mars are twin brothers, we are also very clear that the earth can breed its own life, but Mars can't. It must have its own uniqueness. Let me introduce the specific content in detail.

First of all, the earth is a beautiful home for us, where our human life sprouts, and now it is very spectacular and full of vitality. Nature is also beautiful, it provides us with many natural benefits, and we are constantly using it, but nothing can be used all the time, which will eventually be useful and bad. What should we do at this time? Perhaps the only one that comes to mind first is Mars, because it is most similar to the Earth.

Secondly, astronauts from all over the world are actually considering going to Mars to do experiments to see if it is suitable for human reproduction. Many conditions are basically the same as the earth, but there is a fatal problem that cannot be solved on Mars at present, and that is the source of life, the water problem. At first, both the Earth and Mars were made up of vast oceans and atmospheres, but the final results were different. The earth gave birth to life, and the water vapor of Mars did not know where it went. Therefore, this problem is fatal.

Finally, we can know that human beings are also working to build a Mars with water, so that the conditions of Mars are more similar to those of the Earth. We hope that humans can immigrate to Mars in the future, but this idea is impossible at present. It can only be said that there can be experimenters on it, but we ordinary people still can't live, so there is no hope for us to immigrate to Mars so far.
