Laboratory Miller-Urey experiment

The Miller-Urey experiment, conducted in 1953, aimed to explore how life’s building blocks could form from simple chemicals present on early Earth. The experiment simulated the conditions of the primordial atmosphere using water, methane, ammonia, and hydrogen, along with electric sparks to mimic lightning. After a week, the researchers discovered that amino acids, the building blocks of proteins, had formed. This groundbreaking experiment suggested that organic compounds necessary for life could arise naturally from non-living materials, supporting theories about the origin of life on our planet.
