Alien life
Alien life refers to organisms that originate outside Earth, potentially existing on planets, moons, or other celestial bodies. Scientists search for signs of such life by studying environments that might support life, such as water, suitable temperatures, and chemical ingredients. While we have not confirmed alien life, the discovery of extraterrestrial microorganisms or complex life forms would reveal that life can exist in diverse cosmic conditions. The study of alien life helps us understand the possibilities of biology beyond Earth and broadens our perspective on life's resilience and diversity throughout the universe.
