What evidence do we have for the origin of life from inanimate matter?
Abiogenesis is the generation of life from the inorganic matter. Many scientists gave the theory of origin of life from the non living matter. Then, at last Stanley L. Miller and Harold C. Urey gave the experiment to demonstrate the origin of life from inanimate matter.
Miller and Urey set up an experiment to derive life from inorganic matter to organic. He introduced Methane, Hydrogen and ammonia gases by providing the moist environment above the water containing flask. Then, Miller gave the system an electric current. After a few days he found that flask contained organic compounds and those compounds were amino acids which served as the building block elements of the proteins. By the chromatographic analysis, he confirmed the formation of amino acids. That’s how life originated from the non- living matter.
