There are no reasons and examples of life outside of the earth

Others are keen to look for traces left by aliens in ancient times. They believe that the round masks of the figures on the murals of the Sahara Desert, the megalithic buildings of Easter Island and South America, and the pyramids, among other unexplained prehistoric wonders, are related to aliens. Other scholars have put forward various ideas such as that humans are descendants of aliens, or that some peoples of mankind (such as the Maya) are descendants of aliens mating with earthlings.

But these can only be used as speculations and hypotheses, most of which still lack sufficient evidence.

Carl Sagan, a famous astronomer at Cornell University in the United States, once pointed out that there are almost 200 billion stars in the entire Milky Way, and a considerable number of these stars have planets. Of these planets, which are close to Earth's environment, it is estimated that there may be as many as a million. Since life can arise and evolve on Earth, it is possible that life will also arise and evolve on these planets, and develop intelligent life.

And some of them must be more advanced through the current human civilization. Therefore, these astronomers believe that the emergence of intelligent life on planets other than Earth is entirely possible.

1.The most striking thing about extraterrestrial civilizations is UFOs, which were once widely believed to be alien spaceships. But it turns out that some of these are illusions, and some are deliberately hyped.

2.At least in the solar system, there is no place for human habitation other than Earth.

In fact, the field of human understanding of natural science is quite limited. Who knows if there is life in **. Maybe it's on Mars.

It cannot be judged on the basis of what is suitable for the existence of life. For example, there is a kind of bacteria on the earth that is still alive and kicking in the heat of 3,000 degrees. How do you explain that?

So I believe there are extraterrestrial creatures.

Probably there will be later!

We earthlings may go to the moon and build a lunar village!

There we will create some organic matter and the basic environment for human existence.

There should be, the universe is so big, and it can't be just the earth that is as suitable for life as the earth

As long as there is water, the right temperature, and light. There should be life, but like us, we haven't been with "them" yet! You shouldn't say no!

There are many systems in the universe that have such relationships as the sun and the earth in the solar system. As long as there is water, there is the possibility of living things.

I believe that there is life beyond the Earth.

It must be that the universe is so big, the earth is just a small star in the vast stars, and there must be planets suitable for biological life in the universe, and our human understanding of space is only a drop in the bucket. The earth has only developed for 4.6 billion years before we humans appeared, and there are more planets in the universe that have more development years than the earth, and there are planets suitable for life, so there must be life on other planets outside the earth.

There is a high probability that there is a pure amusement in life outside the earth. So far, human beings have not discovered life outside the earth, but according to scientific speculation, there is a high probability that there is life outside the earth, since there is life on the earth, then in the vast universe, it is entirely possible that there is life, but human beings have not yet been able to detect it.

The Earth is not unique in the universe, planets like the Earth are almost all over the universe, and the possibility of extraterrestrial life is very high.

The search for extraterrestrial intelligent life is the process of human exploration of the unknown world and the process of understanding the universe and life.

In the universe, the existence of life and even intelligent life is by no means a phenomenon unique to the earth, and although life in the universe is difficult to find, human beings are not alone.
