String Theory and God

Why do most physicists discount the obvious connection between string theory and the supernatural? Why do they insist that the extra dimensions necessary for there to be no mathematical infinities or anomalies must be compacted because we cannot detect them? Perhaps our finite brains were only created to comprehend in three physical dimensions therefore only being capable of designing testing equipment and performing experiments in those same dimensions. Perhaps our spirit exists in all dimensions, whether it is ten as in the many variations of string theory or eleven as in M-theory, but we are limited by our bodies to the three that we experience. I once read a book by Robert E. Faid that proposed that heaven could exist in three dimensions somehow parallel or perpendicular to our own and hell in another three with time transcending all nine physical dimensions. To me this makes more sense than theorizing that, during the big bang, the other dimensions compacted themselves into a size smaller than the Planck length. Imagine that in death, our spirits free from the confines of the physical body exist in higher dimensions and enable us to more fully experience the presence of God.
