The traditional reply by atheist philosophers, is that you are applying the parts to the whole (all parts need a cause, so the whole thing needs a cause), in case of infinite regression. However, another way to think of it, is not in this way (parts to the whole) but through induction. If you see through induction, that infinite regression would still need a cause, then it's not applying parts to the whole.
As for the inductions, it's to see the pattern, will remain in a infinite from the finite case. And this is true. No matter how long the line (even of infinite size), they are all effects, and hence need a cause. It's through induction, and not saying, because the whole thing is effects, it requires a cause.
It's subtle, but if you see infinite regression requiring a first cause through induction, it's a solid and there is no refutation. If you see it through parts to the whole, it's a unproven reason, and unproven proof.
