It is the general trend that human beings migrate to extraterrestrial planets. Is the life span of extraterrestrial civilization really much longer than ours?

We all know that the deterioration of the earth's environment poses a threat to the living environment of mankind, and people hope to find a livable planet as soon as possible. For many years, scientists have not found the existence of alien life. They believe that if there are extraterrestrial life on other planets, their life span will be much longer than that of human beings. The environment of the earth is far from the ideal at the beginning of its birth. All kinds of environmental pollution and resource shortage are plaguing the further development of human civilization. Only by moving to other planets can human beings continue to exist in the universe. Scientists have been studying Mars for a long time, hoping to move humans to Mars. Unfortunately, there is no conclusion yet, because they are not sure whether there is extraterrestrial life on Mars.

1. Scientists believe that there is extraterrestrial life on other planets, and its life span may be several times that of human beings. The reason is that they don't need to be bound by gravity, because there is no gravity, so their bodies can grow as they please. At first, scientists focused on exploring the planet where oxygen exists. Later, they thought that alien life was likely to have different lifestyles. Alien life may not rely on oxygen to survive, but they have their own unique way of life. Scientists speculate that it may be because of this that nothing has been achieved for so many years. The formation of extraterrestrial life cannot be realized in a short time. Maybe human technology has been further developed to find them.

Second, scientists still haven't given up looking for extraterrestrial civilizations, because they still don't believe that only the earth has given birth to life in the universe, and they firmly believe that there are other civilizations. However, all this is unknown to us, so scientists will adjust their research ideas and try to find extraterrestrial civilization in other ways. Only in this way can we promote the development of mankind and make the life of the earth last forever.

For human beings, we have lived on the earth for a long time, so at present, we have become the rulers of the earth. However, this cannot be static. Take the dinosaur era 65 million years ago as an example. At that time, there were a large number of such dinosaurs living on the earth, and it was impossible to make them extinct in a short time. This is related to the operation of the planet, so we are the same on earth. If we are not careful, we may disappear from the earth. Speaking of interstellar migration, it should be the future trend and necessity of human development, which is closely related to the current human activities on the earth.
