Stanley Miller conducted the famous Miller-Urey experiment in 1953, which demonstrated that amino acids, the building blocks of proteins, could be formed under conditions simulating early Earth. This experiment provided support for the hypothesis that the building blocks of life could have arisen from simple chemical reactions on a young Earth.
The origin of life remains a subject of scientific investigation with no definitive answer. Various hypotheses and theories have been proposed by scientists such as Alexander Oparin, J.B.S. Haldane, and Stanley Miller, but the exact mechanism of life's origin is still unknown.
Stanley Miller was given an Oparin Medal for his work contributing the "origins of life."

Miller and Urey set out to test a part of Oparin's hypothesis on the origin of life.
Harold Urey and Stanley Miller were able to prove the hypothesis that conditions during the early portion of earth's formation were conducive to complex chemical reactions. These reactions formed amino acids, which are the bases of organic compounds that lead to life on earth.

many of the lipids, carbohydrates, proteins, and nucleotides required for life can form under abiotic conditions
In 1952 Stanley Miller and Harold Urey of the University of Chicago conducted experiments in possible chemistry of early earth. To determine how certain molecules needed for life could be formed. The reaction vessel had a mixture of H2O,CH4,NH3,H2,N2,CO2, this was heated and an electric current, sparks, passed through it, to resemble lightning. It was allowed to run for one week, 2% of the reaction mixture was amino acids, 22 amino acids have been found. Some sugars and lipids are also formed. The reaction products are optical isomers the solution is racemic. The yields are low. Some people claim that the results support an abiogensis origin of life. It is not the preferred method of producing amino acids. One may wish to read up on "panspermia" , "abiogensis" and "origin of life" in a search engine.
