Proof?? Yes, the AAAS undoubtedly "has an issue with God in philosophy" as long as you're talking about the philosophy of science. In specific, the constant attempts to foist off "creation science" as science---which it is not. But as a general point of philosophy, I seriously doubt it.
Proof is in pudding. The “creation science” corner (a relatively new phenomenon in American Christianity) is a convenient straw man.
