Explanation:
Detailed explanation-1: -But to refresh your memory: in 1952 Stanley Miller and Harold Urey simulated the conditions of early Earth by sealing water, methane, ammonia and hydrogen in a glass flask. Then they applied electrical sparks to the mixture. Miraculously, amino acids came into existence amid the roiling mixture. It was a big deal.
Detailed explanation-2: -They designed an apparatus which held a mix of gases similar to those found in Earth’s early atmosphere over a pool of water, representing Earth’s early ocean. Electrodes delivered an electric current, simulating lightning, into the gas-filled chamber.
