Theory life came from non-living matter
WebbAbiogenesis is the origin of life from non-living matter. And it has been a burning question for some time (since long before Darwin came up with the Theory of Evolution). But … WebbSpontaneous generation is a superseded scientific theory that held that living creatures could arise from nonliving matter and that such processes were commonplace and regular. It was hypothesized that certain forms, such as fleas, could arise from inanimate matter such as dust, or that maggots could arise from dead flesh.

In biology, abiogenesis (from a- 'not' + Greek bios 'life' + 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.
