Abiogenesis, in its most general sense, is the hypothetical generation of life from non-living matter. Today, the term is primarily used in the context of biology and the origin of life.

biogenesis The doctrine that life originates only from preexisting life.
biogenous sediment The type of sediment that is made up of the skeletons and shells of marine organisms. Also see calcareous and siliceous ooze.

abiogenesis Early theory that held that some organisms originated from nonliving material.

Since abiogenesis is rare or impossible under modern conditions and common descent (especially macroevolution) is a slow process, global biological diversity requires that the Earth is very old.

Furthermore, because it is not part of evolutionary theory, abiogenesis also is not considered in this discussion of macroevolution: abiogenesis is an independent hypothesis.
