Rebuttal to Natural Theology
1. A prime mover would be sufficient but not necessary for the existence of the universe.
So far, so good.
But now we have what's called an "argument to the best explanation": namely, when we have various possibilities before us, we examine them and see which one we are most justified in believing. This, to be sure, is not absolute...but it can be very, very probabilistically winsome, if the right comparisons are made.
So let's make the comparisons. Other than an intelligent First Cause of all things, what's the more winsome hypothesis? What ELSE do we know that could account for the measure of complexity, order, intelligence and so forth that was infused into the original cosmos, and which we still find on every side today, as science progresses?
I suspect you'll have nothing to suggest. If so, you're pretty much in the same situation as everybody else. Concepts, for example, are thought to be eternal and unoriginated, things recognized rather than invented. But concepts don't create things. Or numbers...numbers are sometimes thought to be eternal realities, but numbers also don't create things. So what's your candidate, to set over and against the First Cause hypothesis?
If you've got nothing to propose as rival, then at least for the present, that makes the First Cause (i.e. an intelligent Creator) the "best explanation," rationally speaking.
2. A prime mover is an imaginary being.
Well, I don't know what you mean by "prime mover." I'm pretty sure you don't mean the Aristotelian "primum mobile," so I'm going to assume you mean First Cause. Correct me, if you think you mean something else, please.
You would need evidence for this objection to be serious. What have you got?
3. An infinite regress is no more impossible than an infinitesimally small number.
No, that's certainly wrong. We know that much.
Infinity is not "a small number." It isn't even
comparable to some number. In fact, it isn't actually a "real number" at all, mathematically speaking. It's a placeholder concept for an unending or unbeginning entity, or one that recurs without cessation, like the sequence of digits ideally following "3.14..." in
pi. Thus, the one thing it never does is terminate in any "number," whether big or small. That's what makes it infinity.
