But it's not a necessary entity. Shave it off. Occam's razor isn't just about picking the simplest explanation, it's about picking the simplest explanation consistent with observation. It is sometimes stated as: Among competing hypotheses, the one with the fewest assumptions should be selected. God is a big assumption. A more complex hypothesis can be preferable to a simpler one under the razor if the additional entities in the complex hypothesis are necessary.
