Well, it can if you approach the existence of God the way you approach any other natural scientific question, with hypothesis and experimentation, but that begs the question of whether or not God is something we believe in, primarily, because of scientific evidence. He is not, however. The fact is, Occam’s Razor cannot be used to “slice the involvement of God” or to prove the involvement of God. Atheists believe it nullifies the need for God because it does seem to destroy the linear idea we have of the universe’s creation when considering these other cosmologies, whether its the inflationary model, or Turok and Steinhardt, or another. But as Jim said, there’s no reason God could not create a universe that appears to have been created non-linearly. Even if the prevalent model was for an “infinite” universe or series of universes, I and many other theists would still be compelled to ask, “Why anything at all?” To me and many others, the principle of Occam’s Razor suggests that there is anything at all only because an infinite creator, the last chain in the link, the Only One Who Needs No Explanation, created the universe.
