The interest to discover intelligent civilizations on other planets our galaxy and outside of it is a concern that astronomers have had for many years since, according to estimates made from the drake equationit is believed that a galaxy with billions of stars and solar systems would have at least a few planets with intelligent life with enough technology to communicate.
For this reason, it does not seem strange that given the large amount of data that we have about the universe, people wonder if Is there intelligent life on other planets? And why haven’t we discovered it?
This and other hypotheses are explained by the Fermi Paradox, who gave some examples to understand if there is alien life on other planets and if so, why they have not contacted us or perhaps colonized Earth.
Henry Fermi was a physicist in Italian known for developing the firstr nuclear reactor, who, among his various investigations, dedicated himself to looking for the contradictions that exist between the estimates that ensure there is a high probability that there are intelligent civilizations in the universe.
The Fermi paradox It arose in the summer of 1950 when Enrico Fermi was with his colleagues, Edward Teller, Herber York and Emil Konopinski and the subject of the existence of extraterrestrial life in our galaxy, the Milky Way, came to mind.
As he could not find a contradiction to this possibility, the physicist raised the possibility that, if there were an intelligent civilization like ours or superior, perhaps it would have already visited us since our solar system is one of the youngest stellar complexes with 4.571 billion years.

Before the emergence of the Fermi paradox Some potential solutions emerged, among which it is pointed out that perhaps we are overestimating the prevalence of intelligent life in the universe, we are looking at the wrong place, intelligent life is very rudimentary and it is too early to detect it.
