alien life theories

Alien life theories explore the possibility that life exists beyond Earth. Scientists consider conditions like water, energy, and suitable chemistry necessary for life, which may occur on planets or moons within our galaxy. Some theories suggest life could be microbial or intelligent, often inspired by the vast size of the universe and discovery of exoplanets. Evidence remains inconclusive, but ongoing research and space missions aim to detect signs of life or habitable environments elsewhere, fueling scientific curiosity and understanding of life's potential diversity and resilience in the cosmos.
