What question were miller and urey trying to answer?

Miller and Urey were trying to answer the question of how life could have originated from non-living chemical substances on the early Earth. Their famous experiment simulated the conditions of the primordial Earth, including a reducing atmosphere and energy sources like lightning, to see if organic compounds essential for life could be formed. They aimed to provide evidence for the abiotic synthesis of organic molecules, which could lead to the emergence of life.
