Detailed explanation-1: -life. The first idea to capture scientists’ attention was the “primordial soup”: the notion that when Earth was young, the oceans were filled with simple chemicals important for life. These would eventually self-assemble into simple living cells.

Detailed explanation-2: -The idea of the primordial soup was originally proposed by Alexander Oparin and John Haldane as a possible explanation for the creation of life on our planet. The theory states that if energy is added to the gases that made up Earth’s early atmosphere, the building blocks of life would be created.

Detailed explanation-3: -The soup theory was proposed in 1929 when J.B.S Haldane published his influential essay on the origin of life in which he argued that UV radiation provided the energy to convert methane, ammonia and water into the first organic compounds in the oceans of the early earth.

Detailed explanation-4: -According to the theory, organic compounds essential for life forms were synthesized in the primitive Earth under prebiotic conditions. The mixture of inorganic and organic compounds with water on the primitive Earth became the prebiotic or primordial soup.
