If human beings discover a new livable planet, is it really possible for human beings to all move?

At present, the ecological environment is increasingly tense, and the relationship between man and nature is also increasingly tense. Humans have been thinking about how long the earth can support human life and reproduction. After scientists' accurate speculation, the life of the earth is also limited. What we can do is to find a new planet suitable for human survival before the earth is destroyed, and then immigrate there together. But in my opinion, it is impossible for all human beings to immigrate to the past. Because the distance is too far, the number of people who can be transferred at a time is limited, and it is impossible for human beings to immigrate to the past with the current level of science and technology.

With the depletion of the earth's resources, the time for human survival on the earth is naturally more and more urgent. China, the United States and European countries are now looking for livable planets, and Five-hundred-meter Aperture Spherical Radio Telescope (FAST) is also constantly looking for livable planets, and there have been successful examples. But to truly immigrate to the planet in outer space, human beings must have five key technologies.

On any livable planet, if you want to have life, you need some conditions, such as not being too close or too far away from other stars, and there should be liquid water resources on it. There must be no less iron on the planet, otherwise it can't be a terrestrial planet. And after these conditions are met, it will take about 3 billion years for life to appear.

So far, scientists have discovered some planets that may produce life through various scientific means, such as Kepler-186f, which is almost exactly the same as the earth. This is a rocky planet that scientists have identified. Kepler-186f is very similar to the earth in the distance from the star. It can be said that Kepler-186f is almost a replica of the earth. It's just that Kepler-186f is close to 500 light years from the earth, which is a bit far.
