The earliest kent life-forms on Yird are putative fossilised microorganisms, foond in hydrothermal vent precipitates, that mey hae leeved as early as 4.28 billion years agae, relatively suin efter the oceans formed 4.41 billion years agae, an nae lang efter the formation o the Yird 4.54 billion years agae.[1][2]

Abiogenesis, or informally the oreegin o life,[3][4][5][note 1] is the naitural process bi that life arises frae non-leevin maiter, sic s semple organic compoonds.[6][4][7][8]

Oparin, in the 1920s, the intellectual challenge of the origin of life enigma has unfolded based on the assumption that life originated on Earth through physicochemical processes that can be supposed, comprehended, and simulated; that is, there were neither miracles nor spontaneous generations.

[...] Since the early 20th century the phrase OoL has been used to refer to the events that occurred during the transition from non-living to living systems on Earth, i.e., the origin of terrestrial biology (Oparin, 1924; Haldane, 1929). The term has largely replaced earlier concepts such as abiogenesis (Kamminga, 1980; Fry, 2000).

According to the conventional hypothesis, the earliest living cells emerged as a result of chemical evolution on our planet billions of years ago in a process called abiogenesis.
