“Excuse my saying so, but obviously the origin of life can be traced to a physic-chemical event. The dispute addressed in this article is whether that event occurred spontaneously or by design.”
Yes. But that is true of any and all of the changes that occur over time in the theory of common descent.
I am not sure what you are addressing or what point you are making.
I thought you were arguing against what is called abiogenesis being addressed by evolutionary theory.
There appears to be no testable explanation as to how abiotic chemicals “evolved” into molecules, rather than the expression of a belief that such an event must have occurred.
