Oh my God (forgive the pun). Come on now! This is why atheists annoy me! Straw man arguments against christianity, repeating dysfunctional analogies! Please!
Let's examine again the attempt to disprove God.
Ok, so we want to disprove God. In general, disproving anything is difficult. One can always add "epicycles" to a theory to make it stand up to new observations or tests. Essentially, we have two tools in our arsenal- we can attempt to create a contradiction between evidence and the theory or we can use occums razor. Either of those could potentially give us a logically justifiable disproof of God.
Let's try option number one. What evidence can we use? Well, we could bring out all kinds of things, from sciences contradicting biblical claims to the very pyscology of where humans get the concept. The thing is, ultimately none of these succede in doing anything but ruling out specific Gods. The theist could counter by adjusting his definition of God and will always be able to find some description that survives any test. So this option fails.
But hah! Little does the theist know of our other weapon, occum's razor. We have led him into our trap. Surely, if the original concept of God was not silly enough to be hacked off, it must be now, as God's definition has been tweaked and complicated to fit observations. So, we shall attempt it. But it seems we have another problem. Occum's razor doesn't seem to work. First of all, occum's razor is used to differentiate between theories. We have no other complete theory of the universe to compare the theist's claim with. And second, there is no way to objectively define absurdity. How do we know which is more silly, a universe created by God or one that can stand upon it's own self? We can't, because we know only our own universe (and I daresay our grasp of it is pretty poor, atleast right now) and have nothing to compare. It seems we're stuck.
But of course, the theist has nothing to support his claims either (atleast none that are objective or verifiable), so no need to surrender. But our objective cannot be completed and we have to withdraw.
Almost every single argument I've heard from atheists can be generalized to fit into one of the two above attempts. All the analogies, the "invisible whatever" arguments, the claims of absurdity. They all make use of the same logical process, one that doesn't work in this special case. Normally it would. You can use both of those tools on essentially anything and get the result you want. They are both absolutely key to science. But they fail here. It's not surprising that people would rely on them for disproofs of God as they work so well in seemingly comparable situations. It seems almost counter intuitive that they don't work. But against God, even these mighty weapons are useless. We are left without even a probablilty.*
Of course, there's Perfection and his argument for scientific completeness through induction, which would give us a way to use occum's razor. But I dispute it based on other inductive arguments. If someone wants to continue on this point, that would make sense. But let's stop going back to square one with the analogies and whatnot (unless you think I'm wrong in my rebutle of it, in which case please post why I'm wrong).
*Though it seems others in the thread have proposed that actually you can find a probability. Care to show me how? Is it more subjective (and therefore specific to a person) or...what? I really am interested.
