I believe I either said, or directly implied, it is a scientific fact.
Science cannot accept supernatural explanations.
It cannot be proven that abiogenesis was a providential miracle. Maybe it was.
But that is the realm of theology.
The fact that all cells, all DNA molecules, all genes, all proteins, all amino acids are all constructed from a few basic elements found widely in the environment - carbon, hydrogen, oxygen, nitrogen, phosphorus -- indicates scientifically that life arose from a pre-biotic soup of inert chemicals.
That is abiogenesis. There is no other way scientifically to read those facts.
Even the cop out of saying life was seeded from another planet cannot escape the conclusion that life emerged from the complex organization of very basic and common chemicals. At the elemental and atomic level, there is nothing exotic about life. Atomically, it is made up of the same stuff the universe is.
The question is, we do not know what the chemical or physical mechanism is that kick started biological emergence.
