We can obviously agree to disagree. I do think it makes sense to take what one thinks to be the most reasonable stance on a question and look for a reason reject that stance. I don't see it as merely saying, "God exists because you can't prove he doesn't." I see it as more, "I believe god most likely exists because I find it to be the most reasonable explanation for the following reasons, but I am willing to amend that view if a better explanation comes along." I'd rather it be characterized as a "God of Gaps," argument than an "Argument From Ignorance", although I disagree with both evaluations.
