Leaving aside criticisms of causality itself in both philosophy and quantum physics, I would like to simple point out that in your analogy of the dead body and the wire, you forcibly inject God into it. If I were a police officer at a crime scene, I would conclude that the dead body was caused by the wire because I
saw it right there and made inductive conclusions. This example is ridiculous when compared to the
existence of a supernatural entity. No one is denying the existence of the wire because it is
perceivable through the senses. The unmoved mover (to use the Aristililean term) is no where in the picture in scientific revelation, He is merely semantically injected into it as the definition of the
cause of the revelation
a priori. To summarize it, you are assuming that God is even there, and thus the cause. The wire
is there and thus can reasonably be concluded to be the cause.
Now I'm not even an empiricist when it comes to these deep philosophical questions of the universe, but I am as almost everyone else is when it comes to everyday life. This is why I've disliked these analogies which are so simplistic and hardly match the question at hand.
