 Notice that the general strategy of the particular version of the low priors argument discussed above is to find an alternative to omni-theism that is much less specific than omni-theism (and partly for that reason much more probable intrinsically), while at the same time having enough content of the right sort to fit the totality of the relevant data at least as well as theism does. In other words, the goal is to find a runner like source physicalism that begins the race with a large head start and thus wins by a large margin because it runs the race for supporting evidence and thus for probability at roughly the same speed as omni-theism does. This doesn’t show that source physicalism is probable (a “large margin” in this context means a large ratio of one probability to another, not a large difference between the probabilities), because there may be even better runners in the race; it does, however, show that omni-theism loses the race by a large margin and thus is very probably false.
