Socratus,

You started with two questions and then you attempted to answer a question without thinking it through.

You asked "Where and Who is God ?"

There is only one place where "God" has been demonstrated, even proven to exist - in human brains. Unlike "a chair" the effects of which we can experience directly, the inference of "God" as something more than a "concept" exists at the end of a long, evidence-free path of obscurantism, bloviating linguistic abuses, and general poor reasoning.

There is no evidence that God is a "who," but substantial evidence that God is a "what." It's an arrangement of electrochemical potentials and impulses in the Brain induced by poor reasoning and used to fill a void created by want - want of evidence, want of security, want of influence, want of recognition.
