(1) The Universe is contingent upon "prior" conditions (conditions that existed "prior" to our understanding of space/time:
(a) Prior condition being space/time, or gravitational field.
Matter, energy, all physical phenomena stem from 'gravitational field' the prior condition of which is he big bang, the prior condition of which is the singularity, the prior condition of which is...we do not know.
(b)All naturalistic phenomena are empirically derived, thus they are contingent by their very nature.
"There is not a shred of evidence that the universe is logically necessary. Indeed, as a theoretical physicist I find it rather easy to imagine alternative universes that are logically consistent, and therefore equal contenders for reality." First Things: Physics and the Mind of God: The Templeton Prize Address (1999)
(2) By definition the "ultimate" origin cannot be contingent, since it would reuqire the explaination of still prior conditions (a string of infinite contingencies with no necessity is logical nonsense;the existence of contingent conditions requires the existence of necessary conditions).
(3) Therefore, the universe must have emerged from some prior condition which always existed, is self sufficient, and not dependent upon anything "higher."
(4) Naturalistic assumptions of determinism, and the arbitrary nature of naturalistic cosmology creates an arbitrary necessity; if the UEO has to produce existents automatically and/or deterministically due to naturalistic forces, the congtingencies function as necessities
(5) Therefore, since arbitrary necessities are impossible by nature of their absurdity, thus we should attribute creation to an act of the will; the eternal existent must be possessed of some ability to create at will; and thus must possess will.
(6) An eternal existent which creates all things and chooses to do so is compatible with the definition of "God" found in any major world religion, and therefore, can be regarded as God. Thus God must exist QED!
The state of understanding most Christian apologists use for the cosmological argument is very bad. Most of us are still back in the enlightenment, or even earlier. In fact if one reads the Boyle Lectures (that's 1690's) one sees all the issues of a modern apologetics message board, with very little real advance by the Christian apologists.
The problem revolves around the notion of causality. Causality requires linear direction and time. A causes B, it follows that a precedes B in a sequential effect. No Time means no sequential order, thus no cause. Time begins sequentially simultaneously with the Big Bang. So there is no way to speak of "before" the big bang because there can't be a "before time." Since time is the beginning of sequences there can be no scenic before the beginning of sequences; without sequences there is no begging and no "before." So the problem is that it is meaningless to say things like "everything that begins requires a cause." This is meaningless because we can't really speak of "the beginning" of the universe since the begging of the universe is also the beginning of time, and causality requires time. Thus there is no cause before the beginning of causes. Thus the whole idea of a final cause beginning the sequence that eventually leads to sequences is a lame idea. Yet most Christian Apologists use the Kalam argument (made so poplar by William Lane Craig) which begins "everything that begins requires a cause." The statement itself is self contradictory.
Of course the atheists muck things up even worse with their notions of Quantum theory (AKA "QM"). It seems that everything that begins doesn't require a cause. QM particles pop into exist seemingly out of nothing with no prior casual agent that can be decreed and thus, it seems something could come from nothing. Now it gets tricky at this point, because this not really what's happening, but the best that can come out of this observation is a big muddle.
It seems that we really don't find QM particles "popping" out of "nothing." They emerge from something called "vacuum flux." This is just a fancy name for more QM particles, that doesn't' matter, because it really is not actual nothingness. The problem is that physicists speak of VC as "nothing." So while one finds physicist speaking of QM being something from nothing, they know quite well its not. Now the tricky part is, the Christian apologist suspects, but we cannot prove, that there is a cause in there somewhere. But the skeptic can always elude the obvious implication of a cause since we don't have a direct observational proof of the need for a final cause. Our assumptions about final causes are pinned upon logic and not upon empirical observation (and this is of necessity, since we can't observe final cause since we can't observe "before" the begging of sequential ordering in time).
It seems that the skeptic has a built-in fail-safe to create a stalemate without he CA (cosmological argument) because our thinking as Christian apologists is often rooted in the thinking of the Robert Boil and the 1690's. We still think in terms of cause and effect, things begging, things needing causes and beginnings and logic proving this rather than empirical observation; although a large part of this argument is merely psychological, since in all fairness the skeptic can't prove anything either and we know darn well there has to be a cause back there somewhere.
I have developed an approach which I feel resolves this dilemma and lends a positive presumptive appeal to the CA. I feel that my approach changes the burden of proof in the debate because lends the apologist presumption, by meeting the prima facie burden of proof. This approach works in two phases:
(1) Sets up a "comfort zone" for the argument, or in other words, establishes criteria through which the bar is lowered for the standard of proof and the lower standard can be met; lower standard meaning "rational warrant for belief" rather than "proof."
We are not out to prove the existence of God. We are out to prove only that it is rational to construe the universe as the creation of God.
The outcome of a prima facie argument is that the burden of proof is reversed. Now it becomes the other side's burden to show that the PF case has not been made. What is it in my version of the CA that swings this point over from burden of proof to PF case? It's the way I deal with the notion need for causality.
The standard Christian apologetics approach is usually to say "everything we observe needs a cause, so the universe must need a cause." This leaves the skeptics cold and they just keep harping on their QM stuff. My approach is to move away from the need causes. I no longer call my argument "first cause." I use the term "cosmological" but not "first cause" or "final cause." I don't speak of causes and I never claim "everything that begins to exist recks a cause." Most skeptics will be expecting this, usually they are thrown into a state of total confusion when they learn that I don't bother with this.
My approach is to use the scholastic model of necessity and contingency rather than cause and effect. Now one might think this is so old fashioned and pre modern that it would be untenable. But no, it's the basis of model logic. One can easily argue, what with the return to the impotence of the model aspects from Hartshorne and Platinga, and with Godell's OA being based firmly upon necessity/contingency, that category is alive and well. Now skeptics will remain incredulous of course, but the category can be defended easily with Spinoza's chart of modalities. The categories are there in logic and cannot be denied.
Moreover, move on from that point to speak of "prior conditions," rather than causes. The idea of prior conditions is tricky, since we all there is a cause lurking somewhere behind it. But the skeptic is lambasting us for speaking of causes, and with this approach we need not speak of them. That way the obvious need for one is enthemimatic; that is the skeptic will pick it out himself, but he can't really say anything about it we aren't claiming it as part of the argument. If the skeptic brings it up, well it's a straw man argument, even though it's really there in the background.
Prior conditions is a tricky category and I have the following analogy. In QM theory we face the concept of the VC and the particle emerge from it. We know from observation that this slows way down the closer one gets to the singularity, and we know that we have no observations whatsoever from timeless state (how could we)? Three conditions obtain in which Amp's emerge: (1) the emerge amid physical law. Even though they seem to contradict our previous understanding of law, they are not opposed to it and QM theory is the business of showing how we can assume their harmonious existence with physical law; (2) They emerge in time; since we have no counter observation we must assume so; (3) They emerge from VF. Skeptics have howled and said "that must means more particles." But so what? that's still something. It means they aren't coming form real nothingness. As long as something exits prior to the "first" existent, that existent is not first and what prior to it must be accounted for. IF we don't wish to end up in an infinite causal regress, then we have to assume that there is some prior conditions which is the basic condition of all existence.
It's like fish. Fish are not caused by water. You can't say "water = fish." But, fish are always found in or near bodies of water. You dot' find fish living in the sand in the desert. There are fish which are native to the North American desert, but they live in water deep in caverns and have actually lost eyes because they live in total darkness. But again, the one prior condition we have for fish is water. Now someone will say "but there is causal relationship there." Yes, but my argument doesn't require that there be no causal relation, but I don't have to push the causal relation to win the argument; all I have to do is demonstrate that there must be some eternal prior condition that is necessary for all contingent conditions to be; and of course we construe this "eternally prior condition" as God.
Another important aspect of this argument is to get away form time. We must get over the simplistic idea that BB is the moment of creation and "before" that (which there is no "before") is God in eternity. That treats time like a place that one could go, where God is. Time may be running eternally, it has a "reassert" with the Big Bang but it doesn't' have to be a "place" one could go to visit. Thus it may not be that we can think of the timeless void as a realm beyond the natural realm.
In this argument I set up the contingency of the universe as the predication of an ultimate prior condition. Anything naturalistic is automatically contingent (this can be backed up by Carol Popper and many others). Thus the ontological necessity which predicates these contingencies is a priori some from of prior condition which must be understood as eternal and boundless, otherwise the idea of a contingent universe filled with individual contingencies makes no sense.
From there the argument that this eternal prior condition is equivalent to or can be construed as an object of religious devotion is easy. Of course atheists will fight tooth and nail to keep from accepting the notion that the universe is contingent. They will charge that this is the fallacy of composition. Don't let them! The fallacy of composition only works when the parts are different. In other words, if a brick wall is made up of all bricks then it is not a fallacy of composition to say "this is a wall of bricks." Thus, one case say "this is a universe of contingencies, thus, it is a contingent universe." Moreover, Dr. Kooks (Univ. Texas--our fine main branch in our Glorious UT system) uses memeology (a funky kind of math stuff) to argue that wholly contingent parts make for a wholly contingent situation. In other words, a universe made up of all contingent parts is a contingent universe. Establishing this point will be the hardest part of the debate, but the skeptic will be scratching his head and asking "what's mermology?"
From there one directs them to Dr. Koons' Website.
I think this approach offers some unique features that get us way from the 1690s and put Christian apologetics in the 21st century.
1) Qumantum Theory does not prove something from nothing.
2) Hawking's Theory Not Answer
3) Not fallacy of Composition.
