@neologist,
Context is everything. We're not talking about trusting one's spouse. We're talking about making a truth claim about the existence of something of cosmological significance. The claim goes to the very foundations of ontology, epistemology and cosmogony.
To paraphrase a bigger brain than mine, extraordinary claims require extraordinary evidence. If you tell me that you have a pet tarantula, I wouldn't even bother to ask you for evidence unless it was something significant related to a court case. However, the claim of a creator deity is of a much greater magnitude, and the bar for proof is correspondingly high.
Mere a priori reasoning doesn't cut it. The angels dancing on pins thing. Appeals to scripture don't cut it. The scripture is the claim, not the evidence. Easily faked photos don't cut it for the very reason that they're so easily faked. Asking for credulity regarding an issue of such a monumental scale is asking too much.
