Naturalism: the philosophical belief that EVERYTHING arises from natural properties (see primary image) and causes, and any supernatural explanations are specifically excluded.
Abiogenesis is the naturalistic theory that life “must have” spontaneously emerged from inorganic or inanimate matter (chemical forms that do not have life) perhaps billions of years ago. “The important thing to remember” evolutionist point out,”is to note that evolutionary theory is a scientific theory about how life evolved as a premise that life already existed.” This as such is separate from the origin of life.
Naturalists tell creationists all the time that, “Evolution and evolutionary theory are already confusing enough”. (We agree!) Therefore, we should not combine abiogenesis and evolution together because they are different.https://www.learnreligions.com/abiogenesis-and-evolution-249875
However, in the same “atheism and agnosticism” article, the author concedes the point: actually “it is NOT invalid to join the two” based on Biological and Molecular evolutionary explanations required within the very definition of abiogenesis.
Biological evolution and molecular evolution are the basis for naturalistic explanations of abiogenesis. It is true that these do have some relation and overlap in the sense that molecular change (in genes) drives biological evolution. So, it is not necessarily invalid to join the two, especially when you consider that it is hard to draw a definitive line between life and non-life.”https://www.learnreligions.com/abiogenesis-and-evolution-249875
