Detailed explanation-1: -Miller, Urey, and others showed that simple inorganic molecules could combine to form the organic building blocks required for life as we know it. Once formed, these building blocks could have come together to form polymers such as proteins or RNA.
Detailed explanation-2: -The Miller-Urey experiment In 1953 American chemists Harold C. Urey and Stanley Miller tested the Oparin-Haldane theory and successfully produced organic molecules from some of the inorganic components thought to have been present on prebiotic Earth.
Detailed explanation-3: -The experiments showed that simple organic compounds of building blocks of proteins and other macromolecules can be formed from gases with the addition of energy.
Detailed explanation-4: -February 1953 In 1953, scientist Stanley Miller performed an experiment that may explain what occurred on primitive Earth billions of years ago. He sent an electrical charge through a flask of a chemical solution of methane, ammonia, hydrogen and water. This created organic compounds including amino acids.
