Detailed explanation-1: -lightening and solar radiation provided enough energy to transform atmospheric chemicals into biomolecules, which then accumulated in the massive ocean covering the earth’s surface.

Detailed explanation-2: -Theory of Biochemical Evolution: The Oparin and Haldane theory is known as biochemical theory for the origin of life. According to the Oparin-Haldane model, life could have arisen through a series of organic chemical reactions that produced ever more complex biochemical structures.

Detailed explanation-3: -The energy needed to drive the formation of these organic molecules was derived from the sun’s radiation, electrical discharges in the form of lightening, and heat from the cooling earth.

Detailed explanation-4: -Divine creation, evolution, spontaneous generation, and cosmogenesis are the four theories examined.
