Philosophically, the concept of God can work to some degree, as in it is defined as the “IAM”, the alpha and the omega, the infinite “being”, supernatural force that cannot be fathomed by inferior life-forms it created. OK, fair enough, the theory itself is somewhat sound, although incomprehensible for the human mind. Therefore, theory is all the further you can go.
The issue with humans, and therefore religions, is the attempt to define or comprehend the supernatural (by definition is beyond human comprehension) and give it attributes of the natural world. “God is love.” Love is a human emotion, a subjective one at that. Assigning human-perceived attributes to a supernatural concept is oxymoronic. Therefore, if a supernatual “GOD” exists, it is beyond human comprehension, so stating any knowledge about how to “please it” (if it even desires pleasing) does not work.
