I would go so far as to say that god is undefinable and therefore questions of his existence are meaningless.
If anybody dains to define god and claim that such a god exists, given any typical definition, I would believe it about as much as I believe that every dog turns itself inside out on a daily basis. Like, maybe they do. I've never watched a dog for 24 hours straight. But I have no reason to believe it. No evidence, no logical inferrence, nothing.
Belief in God is delusional. But it is a social delusion, and thus persistent. It is also deeply rooted, and not shakable via argumentation. So I don't bother to argue the position. I was raised as a Christian and gave it up as I matured, so I know what it is like to have a strongly held belief, and I don't think less of believers.
