Fermi's Paradox proposes that given the apparent age of the universe, intelligent civilizations should have arisen elsewhere and colonized the galaxy, yet there is no evidence of life outside Earth. The document discusses 22 possible resolutions to this paradox, including: 1) Intelligent life exists but has not communicated due to the vast distances between stars. 2) Civilizations may exist but we have not detected their signals because we don't know where or how to listen. 3) Intelligent life may not exist anywhere else in the galaxy.
