The search for aliens and alien civilizations continues, taking into account the laws of probability that suggest Earth is not the only planet in the universe where life exists.

Scientists have discovered a number of new planets orbiting other stars, such as our own solar system. With the discovery of new planets, the ability to explore space increases every year. However, there is another possibility that scientists have not yet been able to find aliens because they may have already found Earth.

Zoo hypothesis theory
According to the Zoo Hypothesis theory, more technologically advanced alien life exists. This is the main reason for not making contact with the earth. The roots of this theory can be traced back to the Fermi paradox, which refers to the discrepancy between the lack of conclusive evidence of advanced extraterrestrial life and the high probability of its existence.

Similar geological and atmospheric conditions on Earth that gave way to human life must exist elsewhere, given the enormous size of the universe. So, according to some estimates, there could be billions of habitable planets in the Milky Way Galaxy.
According to a recent report, two astrobiologists propose two possible explanations for the question of the existence of extraterrestrial life. The first explanation suggests that the evolution of human-like species is extremely rare. This makes our existence a lonely event.

The second explanation, known as the zoo hypothesis, suggests that intelligent aliens are indeed present and aware of human existence. Therefore, they deliberately hide from people, which is similar to keeping an animal in a zoo.

The Star Trek scenario
However, there are some problems with this theory. Given the presence of a number of alien civilizations, not all of them would be so isolationist as to encounter humans. Another point of contention in this theory is similar to the Star Trek scenario. This suggests that aliens are like Star Trek's Starfleet, operating under the Prime Directive not to interfere with the natural development of civilizations.
