O.K., sandy, few problems with that:
Everything that science has discovered so far indicates that the universe is a closed system. There is no in and out. Everything in stays in; there is no exchange between in and out.
Physicists who understand this stuff tell me that words like "outside" and "the universe" don't go together. As someone said here, it's like saying He's north of the north pole, which is of course the same as saying He's nowhere, or, to put it in other words, imaginary.
If God acts within the universe, then we ought to be able to find some evidence of that action, right? What might that evidence look like? How would a universe with God acting within it look different from one without?
