Today's "vent communities" include tube ... How did the Earth and moon form? The Earth, like all the other planets in the solar system, started out its life as a disc of dust and gas orbiting the young sun.

But that does not answer the question of how life began; it just pushes the issue from earth into space. Scientists speculate about the existence of molecules that preceded genetic material as we know it today. These molecules are supposedly more likely to arise spontaneously from inert material and are self-replicating. How old is the universe, and how did it begin? Throughout history, countless myths and scientific theories have tried to explain the universe's origins.In biology, abiogenesis (from Greek ἀ- a- 'not' + βῐ́ος bios 'life' + γένεσις genesis 'origin') or the origin of life is the natural process by which life has arisen from non-living matter, such as simple organic compounds.
