No - that is flat-out wrong; God is beyond that which He creates - He exists above, beyond and outside nature - because the creator is not a part of the created (that's pantheism). Nature - in the cohesion and intricacy of its design - gives testimony to His hand and presence, but He Himself cannot be "located" via our observational methods unless He chooses to manifest Himself in such a way. "Testable predictions" are very dependent upon 1) the nature of your measuring devices, and 2) the nature of that which you are measuring. Your statements reveal quite clearly your suppositional basis: it's naturalism all the way with you; I don't fault you for that, but understand that - from the Christian POV, your assertion that God can be "tested" like any other hypothesis is nothing short of absurd.
