Detailed explanation-1: -abiogenesis, the idea that life arose from nonlife more than 3.5 billion years ago on Earth. Abiogenesis proposes that the first life-forms generated were very simple and through a gradual process became increasingly complex.

Detailed explanation-2: -Explanation: The concept of chemical evolution refers to the origin of life from non-living matter. According to the available evidence of origin and evolution of life, chemical substances reacted at random to form chemical compounds which then aggregated to form components of biological entities.

Detailed explanation-3: -The Oparin-Haldane hypothesis suggests that life arose gradually from inorganic molecules, with “building blocks” like amino acids forming first and then combining to make complex polymers.

Detailed explanation-4: -Inorganic evolution (Abiogenesis) attempts to explain by chance processes the formation of the world and the universe before the appearance of living things.

Detailed explanation-5: -The Origin of Origins They showed that organic molecules (in this case amino acids) could be created from inorganic materials by natural environmental conditions such as acidic solution, heat and electrical discharge (lightning), without the mediation of enzymes.
