"Perhaps there is a hierarchy of causes, but that again is something different than exclusionary causes. What other kinds of causality are there? Aristotle lists four."
How does that make an untestable assumption (divine interference) better than a testable one (natural, physical causes)?
Others recongize that free causality would not be testable as such. Between the two, the second is the health of a civilization and makes politics possible. That is why better is relative. But the denial of one for the other is an exclusion with consequence.
