Theories about How Life on Earth OriginatesPrimordial Soup Theory - Life began in a "soup" of organic molecules in the early oceans, where energy from lightning or UV radiation helped form simple life-building compounds.Hydrothermal Vent Theory - Life started near deep-sea hydrothermal vents, where mineral-rich hot water provided the right conditions and energy for organic molecules to form and evolve.Panspermia Theory - Life, or its building blocks, came to Earth from outer space via comets, asteroids, or meteorites, seeding life here.RNA World Hypothesis - Early life was based on RNA molecules that could store genetic information and catalyze chemical reactions before DNA and proteins evolved.Clay Hypothesis - Organic molecules assembled on the surfaces of clay minerals, which helped organize and concentràte molecules to form more complex structures.
