Can humans really find a livable planet before the sun disappears?

So far, it is impossible, because human science and technology have not reached this level, and there are no other planets suitable for human survival. Although the idea is really good, can it be done?

If a livable planet has been found outside our solar system, let's cite a place closest to our solar system, which should be near proxima centauri. Even recently, the distance can reach 4.22 light years. At present, our human technology is limited and we can't go to this place. So, even now, we really found a planet that is very suitable for human habitation, and there is nothing we can do. However, Mars is the most likely inhabited planet besides Earth.

1. The distance between Mars and the Earth is close to the sun.

Mars has an atmosphere similar to that of the earth. Although the oxygen content is very small, the same content can be achieved through transformation. Like our earth, it is in the livable zone of the sun. If we can change its magnetic field and atmospheric environment, make Mars suitable for human habitation and create conditions suitable for human habitation, it may be better than finding a livable planet outside the solar system and mass immigration. Fourth, Mars has solid water and even liquid water at its poles. Fifth, there are no intelligent creatures and no human competitors on Mars.

If the level of science and technology is really reached, human beings really have the ability to go to a livable planet. First of all, we should protect some low-level animals and plants. Of course, there is no need to deliberately protect a large number of species. Therefore, it is very necessary to find a livable planet suitable for human habitation. In the future, we will continue to develop science and technology, and believe that human beings can also realize interstellar migration.
