Does extraterrestrial intelligent life really exist, and is there any other life in the universe?

From the observation of the universe to the current space exploration, human beings cannot escape an important fact, whether life on earth is the only one, and whether human beings are favored by the Creator.

Is there really an intelligent creature like us in some corner of the universe, and what is their life?

At this point, things took a turn for the better, and Keelins, an astronomer at the University of Manchester, developed a way to find intelligent extraterrestrial life on other planets, which involved game theory, and he wrote a ** describing his idea and uploaded it to the arxiv preprint server.

There are currently two ways to search for intelligent life on cosmic planets.

One way is to scan the sky for signals from space, which are created by intelligent beings.

Another way is to scan the sky for evidence of exoplanets that appear to be habitable.

Keelins began by pointing out that scientists on Earth did not find signals from creatures on other planets because they did not send any signals because they feared that doing so would attract the attention of unfriendly adversaries.

He further suggested that if other people were there, they might listen as intently as we did, which led to the SETI paradox, in which everyone listened, but no one sent.

This also leads to the question of how such a paradox can be solved. He pointed out that game theory suggests that the two sides should reach some kind of consensus, and that the party that gets more information should send the information to the other party first.

Keelins also suggested that in this case, both sides should try to use what he describes as "common denominator information" to decide whether or not to send a signal to the target.

He pointed out that this kind of information should be provided in a form that could be identified by either party, and he further noted that this kind of signal should start with something very basic, such as transmission, signal strength (the number of starlight blocked by a planet when it moves in front of its star) and so on.

Because such a signal is the easiest to measure and is also independent of any life form, possibly residing on a particular planet, this approach would also narrow down the search to the following aspects: planets are located on a plane relative to our star and vice versa.

He concluded that following such an approach based on available data, the search would be narrowed down to one exoplanet: K2-155 d. He suggested that because it is more obvious to us than the opposite, we first send a signal and then observe and listen for any response.

Finally, based on the inherent information, it is determined whether there is intelligent life on the planet.

In fact, as early as the time period when China's Sky Eye was established, a group of extraterrestrial signals 3 billion light years away have been received, and so far, scientists are also analyzing what this signal means, whether people can really find extraterrestrial life, and whether they will encounter the law of the dark forest on the way to find it.

I think there are other life, because the universe is so big, it can't be that only one of our lives was born.

No scientists have discovered that there is intelligent life on extraterrestrials. So intelligent life does not exist. And there can be no other life in the universe.

Intelligent life on extraterrestrial planets should exist, and Enceladus, as observed by NASA, has an atmosphere and ocean similar to that of Earth, which provides the basis for the birth of life. So there must be other life in the universe.
