Well we could always just put words in his mouth.
Aside from that, for someone who believes god to be a temperamental child, would you say you believe their deity exists, because the theist would certainly believe he does? If anything we are attempting to see it from the view of that theist where all other gods do not exist except their own.
Yeah, I believe that Deity to exist, but not necessarily in the manner in which its worshiper understands.
