The "evidence" that we have is our entire physical universe. What we seek is a rational explanation for this universe--particuarly, the "specificity" of the universe (to use ThatGirlAgain's terminology). Our universe is not some amorphous, uninteresting, inert blob, but rather a highly organized, information-laden, consciousness-inhabited spectacle, which, so far as we can tell, didn't
have to exist.
No one claims to know all of the precise steps which came together to produce this universe, with all of its very specific physical "laws." However, we have the following general options:
1) Chance. This is the "Poof! It just happened!" option. On the one hand, it's form is
like an explanation, but in reality, it is a
lack of an explanation. When we explain something in terms of "chance," it means that we do not have a full and complete causal chain for all of the steps involved. As a practical matter, sometimes we might be wrong to attribute something to "chance." In such cases, there really is an explanation, but we just haven't discovered it yet. But I am not using "chance" in this way here; when I speak of "chance" as the explanation for the specificity of our universe, I mean that there literally
is no complete causal chain which explains the universe from start to finish. In this scenario, the explanation for our universe is simply that it was somehow possible, and we just happened to pop into existence for no particular reason at all, without any need to address the question of whether any other universe(s) might also have popped into existence.
2) Necessity. This is the "Omniverse" option--all possibilities are necessarily instantiated. We don't know how many universes are actually possible, but the simplest assumption is an infinite number. In this universe, I ate Cheerios for breakfast. Although it might seem like I could have eaten Corn Flakes instead, in reality I could not have done so; that option was already taken in some other universe. This explanation eliminates the need to explain why our specific universe came to be: there wasn't any option. All possible universes just
had to become actualized, and it just happens that we are in this universe--with its set of possibilities assigned to become actualized--rather than in one of the multitudes of other universes.
3) Volition. This is the theistic option. In order to rule out this option, we have two options: 1) we could present a very strong argument that our human volition is an illusion, a chimera, an impotent mirage which does not actually cause anything to happen in our universe, wherein absolutely everything derives from chance and/or necessity; or 2) we could present a very strong argument that volition cannot exist in the absence of some highly specific physical substructure (such as our brain).
The first problem with the "volition-as-illusion" option is that we have excellent
prima facie evidence that our personal volition does cause (or select) certain things to happen, for the purpose of realizing some subjective value. This
prima facie evidence is as direct and unmediated as anything could ever be, and so the burden of proof needed to deny the efficacy of our volition seems insurmountable. The second problem with the "volition-as-illusion" option is that we have a diffiicult time explaining how evolution could have produced conscious thoughts
which have no bearing whatsoever on behavior. Conscious thoughts which do not affect behavior in any way cannot have been built and honed according to adaptive advantage, for the very reason that these conscious thoughts produced no behaviors at all. Thus the "evolutionary accident" explanation for SME seems too
ad hoc to be taken seriously, especially since we apparently do use our inner conscious subjective thought life to weigh and evaluate arguments, resulting in specific behaviors every single day.
The problem with the "volition-requires-physicality" option is that we don't know this. We can't know this. When it comes right down to it, we don't even know what "physicality" is. We sometimes assume that we know, but yet appearances can be deceiving. We are not solid masses, but rather mostly empty space. Physicists seem to be finding newer and smaller particles every year, and now we have begun to speak of "virtual particles" as opposed to "real particles." No one has ever seen a virtual particle, or even a real particle; these are just hypothetical postulates that help us explain and predict results of very complicated experiments and procedures, all of which are multiply mediated through any number of mechanical apparati and any number of human observers, each of whom might interpret the results in various ways. At the end of the day, we don't know what our subjective mental experience really is: we can't measure it or weigh it. We can tamper with it in various ways, by poking around in the brain, but this hardly proves that an actual brain is required for SME, any more than a leaky straw proves that there is no water in the glass.
So any way we look at it, we apparently have some sort of "possibility reservoir" from which our very specific universe became actualized. The "chance" option doesn't give us an actual explanation, and it seems entirely
ad hoc. The "necessity" option requires an infinite number of other universes, the majority of which will be amorphous blobs, in order to avoid the
ad hoc problem. But we have no empirical evidence for these other universes, nor can we have ever have any empirical evidence for them, even in principle, since we don't have the luxury of getting outside our own universe to observe these putative universes.
This leaves us with the third option. If this option can be shown to be logically impossible, then we should pick one of the other options--either one, actually, since it wouldn't make any difference if volition is an illusion.
But we don't have any good basis for excluding volition, and every reason for retaining it. The "volition" option is the least
ad hoc, the most privative, and in best accord with our natural sense of who we are as persons. This option alone provides the possibility that some answers to some questions are actually better than other answers. This option alone provides the necessary metaphysical framework for the sort of wordview most of us employ in our daily lives. For all of these reasons and more, most people have been, are, and will continue to be, theists.
