Is there a second planet in the world where humans can live?

Hello 1

It has not been detected yet, but it cannot be ruled out

In addition to the Earth, so far, scientists have not yet detected it in the solar system closest to us. Find a planet suitable for human survival. In addition, other planets are too far away from us. It can be said that water from far away cannot quench the thirst of near. For example, Proxima Centauri, the nearest star to us, is 4.3 light-years away. From this point of view, even if a planet suitable for human survival is found outside the solar system, it will be unimaginably far away. Therefore, based on current human science, Technically speaking, there is simply no ability to move humans to other planets (especially interstellar ones, which are all measured in light years!)! It can be seen that migrating to other planets is just a dream of human beings. It is not that easy!

In addition, regarding the issue of life on earth, we can only say that our earth happens to have extremely harsh conditions for the birth of human beings: it is not far or close to the sun, the temperature is suitable, there is water, and there are The most valuable thing about the oxygen-rich atmosphere is that the earth has not experienced a devastating catastrophe in hundreds of millions of years! Therefore, after such a long period of time, the creatures on the earth (whether they came from outside the sky or were produced on the earth itself) gradually evolved from low-level to high-level, and finally gave birth to human beings, the most splendid flower of life in the universe! It can be said that the birth of life in the universe, like the death of life, is independent of people's subjective will.

The earth is the mother that nourishes human beings, let us protect our mother earth!

I would like to emphasize again that aliens may exist, but the huge distance in space, measured in light years, has become an insurmountable obstacle to the interconnection between intelligent creatures.

You can imagine that even the speed of light of 300,000 kilometers per second would take years, decades, hundreds, tens of millions of years or even longer! What an unimaginably long distance this is! Therefore, the so-called alien visit or invasion of the earth is simply impossible
