Miller and Urey performed experiments to support the hypothesis. In their experiment, they combined , ammonia, hydrogen gas, and water in a closed system and it to mimic conditions on early Earth. After stimulating the system with to mimic , they discovered that were produced. This suggests that early Earth had a atmosphere, leading to redox reactions that catalyzed the synthesis of organic monomers such as .

Explanation:

Miller and Urey performed experiments to support the "Alexander Oparin's and J. B. S. Haldane's" hypothesis. In their experiment, they combined "Methane (CH4)," ammonia, hydrogen gas, and water in a closed system and "Simulate" it to mimic conditions on early Earth. After stimulating the system with a "Sparkling device" to mimic "Lightning Storm, " they discovered that "brown broth rich in amino acids" was produced. This suggests that early Earth had a "Reducing" atmosphere, leading to redox reactions that catalyzed the "spontaneous organic compound" synthesis of organic monomers such as "Amino acids."
