Matt,
Here is the dilemma as I see it;
1) Matter cannot traverse infinite spacetime, therefor God did it. (Violates Occam's Razor once again)
2) Matter can traverse infinite spacetime because your analysis if flawed.
Since you don't provide any references to your statements, I'm assuming you are using the outmoded Zeno's paradox or something like it. Zeno's paradox states that it is impossible for an object to go a given distance since the intermediate steps approach infinity.
If you think of a given task as (1) then the midpoint would be (1/2) and so we get this infinite regression;
{...1/2,1/3,1/4,1/5...} The unit of distance becomes infinitely small, and consequently infinitely difficult.
Unfortunately this is incorrect. Zeno's paradox is solved if you consider time. As the distance approaches infinity, the time needed to travel the distances (that is approaching infitinity) becomes infinitly small.
I'm assuming you haven't read anything about String Theory, so I'm going to give you a little info. Since the standard model of physics falls short of explaining how matter (which you confuse as "universe") works, String Theory proposes some solutions. One of them is a massless particle. You may know that under one of Einstein's theories, an object becomes infinitely massive (impossible to move) as it approaches the speed of light. A massless particle would not be constrained by this, since it has no mass. Consequently, it would be possible to traverse infinite spacetime.
That's just my two cents. I could be wrong (I'm not a phycisist).
None of this, however, has any bearing on whether an invisible guy who likes the number 7, the smell or burning flesh vs plant matter and who has his own palace in the sky, exists or not.
How would that prove that the Bible is true? It wouldn't. You need to remember not to Multiply Hypothesis. You should be more explicit in step two.
