Are there aliens in Centauri?

There must be, and there are many more, but I don't have the ability and time to find them. Searching for human beings has lived on the earth for about two or three million years. Once upon a time, human beings thought that they were the spirit of all things, the only intelligent life in the universe, and even thought that the earth was the center of the whole universe. Later, with the progress of science and technology, people's eyes were broadened, and they realized that the vastness of the universe was far beyond our imagination, and the earth was really too small, and of course it was not the center of the universe. So people imagine that the universe is so vast that there may be an intelligent creature similar to human beings-aliens on other planets. This idea has deeply attracted some people who are keen on finding aliens.

/kloc-in the 6th century, when someone observed Mars with a telescope, they found many staggered meshes, so they thought it was a "canal" dug by "Mars entering". 1935, an American radio station announced that Martians had come to earth, which caused a false alarm. And an English writer created a science fiction novel called "War on Martians", which made many vivid descriptions of Martians and even triggered the birth of a series of novels and movies about Martians.

Are there Martians or not? In the era when there were only telescopes, it was always a mystery. In the 1960s, the spacecraft finally landed on Mars, which solved the mystery that has been puzzling people all the time: Mars is much colder than the earth, its surface is covered with mud and stones, and there are often strong winds, flying sand and stones, and there are no creatures on it, and of course there are no Martians.

After this mystery was solved, astronomers further analyzed that in the solar system, no other planet except the earth has the necessary environmental conditions for biological survival. Therefore, humans on earth are the only intelligent creatures in the solar system. To find aliens, we must go beyond the solar system.

1972, the United States launched the "Pioneer 10" spacecraft and flew out of the solar system on 1987. The metal sheet on the spaceship depicts the image of human beings, the earth where human beings live and the position of the solar system (see the right). 1977, the American navigator 1 brought more information to the outside world, including a sturdy record player and a gold-plated record, which contained dozens of human languages and many musical works (including China's ancient songs). Eager for aliens to receive it.

In order to get in touch with aliens, scientists even made huge and complicated equipment, trying to send information to aliens and receive information from them. However, after many efforts, people still haven't found aliens. Some stories about seeing aliens are just legends, which are difficult to be strongly confirmed.

It is also worth mentioning that there are flying saucers. Many people have seen it. I guess it's a spaceship driven by aliens, but it's just a guess.

So, are there aliens? Scientists have analyzed that there must be many planets like the earth in the universe, and some planets similar to the earth's environment are likely to have aliens. However, as our space and communication technologies are not developed enough, we must redouble our efforts to find them.
