What are abiogenesis and biogenesis?

The hypothesis of abiogensis superseded the earlier theory of spontaneous generation. Prior to Louis Pastour's experiments, people thought that living things could arise from nonliving ones, but the empirical data refuted this idea as it relates to the observable present.

One of the earliest theories of Abiogensis was put forth by Charles Darwin, who hypothesized that life may have begun in a warm, chemically-rich pond at some remote and prehistoric period.

According to cell theory, life originates from life, or cells from other cells. This is known as biogenesis, and it is an observable law that states that life never originates from inanimate substances.

The question of how the first cells came to be arises from a number of theories, including those involving DNA, RNA, proteins, crystals, and even extraterrestrial life. However, none of these theories can explain how the complex information required for a self-replicating cell came into being, and no known natural causes can account for the origin of cells. Moreover, random chance has been shown to be so improbable as to be impossible.

Abiogenesis is the scientific hypothesis that living organisms can arise from non-living matter under certain conditions, while biogenesis is the principle that living organisms only arise from pre-existing living organisms.
