What was the reason for Urey & Millers experiment?
The Miller-Urey experiment was a clever way to obtain laboratory data on the synthesis of organic compounds in natural systems. In particular, they tested the hypothesis that complex organics could be formed in an environment that was similar to that of the early Earth, as they understood it at the time. You can find several comments on the significance of the Miller-Urey experiment in reply to other questions posted on “Ask an Astrobiologist”.
