The Euray-Miller Experiment and the Origins of Life

The video discusses the Miller-Urey experiment, which tested the Opryn-Halden theory that life originated from non-living organic compounds. The experiment simulated early Earth's atmosphere using water, hydrogen, methane, and ammonia, and demonstrated that amino acids could form under these conditions. The process involved heating water to create vapor, which mixed with gases in a spark chamber to mimic lightning. The resulting condensation cycle represented primitive rain. The experiment concluded that simple organic compounds, essential for life, could form from inorganic matter with energy input.

What theory did Stanley Miller and Harold Euray aim to prove with their experiment?
