In 2022, can humans share the earth with advanced alien civilizations that are not aggressive?

If there really is an extraterrestrial civilization coming to the earth, we should guide people to make full use of the earth's resources, optimize the environment and restore the destroyed earth's ecology. And raise the level of human science and technology to a level that can only be reached after thousands of years. Let the living environment of human beings on the earth be further improved and live a happy life. Then we should accept these super civilizations from the universe, which is also conducive to the development of mankind into a broader space.

There are many unfavorable factors for human survival. Due to energy and territorial disputes, the risk of war has increased, military competition is in full swing, and military spending has been rising. The most challenging thing for human beings is the virus they have experienced and predicted in the future, which is the serious existence of human survival crisis. Judging from the harm of coronavirus to human beings in recent two years, unknown virus always poses a potential threat to human beings. Humans are always ready.

In addition, due to the improvement of human cognitive level, the earth can no longer meet the future development needs of human beings, and developed countries have invested huge sums of money to explore outer space and March into the universe to find living space outside the earth.

It is a good thing that the existing outer space civilization actively contacts the earth. First of all, it can help us solve the cure of diseases (tumors, etc.). ) and prevention of plague. Can interfere with human beings and stop hegemonic bullying.

In addition, it can lead mankind to develop into outer space and reduce detours in space research. Whether we can realize the wishes of mankind can only wait and expect slowly.

Of course, there may be aliens underground. I believe that most aliens are harmless. They are highly civilized and will not attack too many civilizations below them.

So far, there is no evidence that aliens have been to the earth, but people have nothing to think about.
