“Do you agree there can be no natural cause for a molecule, only a holy one?” “What we know of natural causes, we learn from observation.”
That a molecule can only have a 'holy' cause is an arrogant argument from ignorance! Just because we don't completely understand the natural processes that give rise to complex molecules, it doesn't mean we are required to use god-of-the-gaps explanations. If this were an acceptable method of resolving difficult inquiry, then we would still be living in a geo-centric solar system where Earth is at the center of the universe. I have known people who have taken this view.
