The Miller-Urey Experiment, conducted in 1953 by scientists Stanley Miller and Harold Urey, aimed to simulate the conditions of early Earth to explore the origins of life. They created a closed system containing water, methane, ammonia, and hydrogen, which were believed to be present in the primordial atmosphere. By applying electrical sparks to mimic lightning, they observed the formation of organic compounds. The experiment successfully produced amino acids, the building blocks of proteins, suggesting that simple organic molecules could form under prebiotic conditions. This groundbreaking work provided insight into how life might have originated on Earth and sparked further research in the field of abiogenesis.
