The Fermi Paradox asks why, if intelligent life is common in the universe, there's no evidence of contact or communication with other civilizations.
The Fermi Paradox addresses the apparent contradiction between the assumption that intelligent life is widespread in the universe and the lack of evidence that we've encountered or heard from other civilizations. Physicist Enrico Fermi formulated the question in the 1950s; its most famous version is: “Where is everyone?”
According to the accepted description, if there are many technological civilizations, they might have left detectable signs or attempted to contact Earth. Among the hypotheses explaining this discrepancy are the immense cosmic distances and the possibility of a “Great Filter” that prevents civilizations from achieving galactic expansion. These are hypotheses, not agreed-upon answers.
There is currently no single agreed-upon answer to the paradox. No evidence of visits by extraterrestrial cultures to Earth has been found, and therefore, there is currently no proof of such contact.
It's the question of why there's no evidence of contact or communication with other civilizations, if intelligent life is common in the universe.

This is the well-known phrasing of the discrepancy between the assumption of many intelligent civilizations and the lack of evidence of contact with them.
No. Cosmic distances and the Great Filter are among the hypotheses offered, but there is no agreed-upon answer.
