You used Occam's Razor like some sort of buzz word, that is, without analysis. Let's assume that Occam's Razor is correct: the simpliest explanation is the correct one. Also, that which is finite is immeasurably simplier than that which is infinite. Since creationism believes that the laws and construct of the universe and everything in it arose at a precise, specific moment, beginning at Time 0, creationism is a simplier explanation than atheistic naturalism, which relies on a series of effects, one proceeding the next, going back to infinity. I don't think one can come up with a simpler explanation for things than saying that the universe arose from the spoken word of God. Therefore, by Occam's razor, creationism is the correct choice between the two paradigms.
You'd like to think so. Unfortunately, this isn't the case.
It seems to me that you are using a caricature of Occam's Razor that has nothing whatsoever to do with reality. Basically, Occam's Razor, when used correctly, comes down to this: if an explanation is to be an explanation at all, then it must have fewer free parameters than it explains. Those explanations with fewer parameters are more likely to be accurate.
Simplicity in this sense does not in any way, shape, or form equate to, "simple to explain." To show why this cannot be the case, I'll use your claim that "God did it" is a simple explanation. If it were true that "God did it" were a simple explanation, then this would be the most parsimonious explanation for
everything. After all, "God did it," can potentially explain anything at all, as given by the postulates used to define God. And the more things that something explains, the better an explanation it is. So, this means that the correct answer to, "What causes lightning," is not, "static electricity buildup," but rather, "God did it." The same is true for cell division, why rocks fall when you drop them, why the Moon goes around the Earth, and so on and so forth.
But this is clearly nonsense: we've demonstrated the efficacy of not resorting to, "God did it," for mundane descriptions of the universe around us. Something is wrong here, and that something is that God is not simple in the Occam's Razor sense. Here's why:
Let's say we want to use God to explain why the cosmological constant is less than 10^-120 in natural units (an as yet unsolved question in physics). Okay, God did it. Now, what does this explanation mean?
Why does God make the value less than 10^-120? What postulates of God lead to him making the value of the cosmological constant so small? The answer is: none. You can't deduce from the properties of God that he would make the value less than 10^-120. It's impossible. Heck, you can't deduce from the properties of God
anything about what he would or would not do: God works in mysterious ways, after all. Therefore, if you want to use God to explain the value of the cosmological constant, you have to add another property to God: "God desires the cosmological constant to be less than 10^-120 in natural units." In fact, you have to do this with
everything that you want to use God to explain, whether it's the origins of the universe, the existence of human morality, the existence of a particular religion, or anything else. Therefore God has one property for each and every property that God is supposed to "explain".
And it's even worse: added onto these properties are additional properties that are exclusive to God, things like omniscience, omnibenevolence, and so on and so forth.
Add it all up, and in order to fully define what is meant by a creator god, you need to use
more parameters than whatever it is you choose to explain. Thus Occam's Razor states that far from being an explanation, proposing a god to explain
anything is
worse than simply throwing up your hands and saying, "It just happens."
