1. Definitions
Following Paul Draper, I'm going to define my terms as follows.[1]
By "naturalism," I mean the view that the physical exists and, if the mental exists, the physical explains why the mental exists. If naturalism is true, then there are no purely mental beings which can exist apart from a physical body and so there is no God or any person or being much like God.
By "supernaturalism," I mean the view that the mental exists and, if the physical exists, the mental explains why anything physical exists. If supernaturalism is true, then there is no purely physical matter which can exist without some sort of ultimate mental creator. "Personal supernaturalism" is a type of supernaturalism; it adds on the claims that one or more personal mental entities exist and, if a physical world exists, it or they produced the physical world for a purpose. "Theism" is a type of personal supernaturalism; it adds on the claim that there is just one mental entity, God, who is all-powerful, all-knowing, and morally perfect.
"Otherism" is a catch-all category. It says that both naturalism and supernaturalism are false.
