The Miller-Urey experiment produced evidence that conditions on early Earth could produce amino acids, which are the building blocks of proteins. This is significant because it supports the idea that the chemical building blocks of life could have arisen from non-living matter through natural processes. While RNA and DNA are also important molecules in the origin of life, the Miller-Urey experiment did not produce direct evidence for their formation.
