Do you believe in God?
It is a poorly worded question, because it steps over a preliminary question, namely "Does God exist?". And to that question, my answer is that I cannot know, nor can anyone else know, with anything remotely approaching the certainty necessary to make a firm conclusion either way. I've yet to see or experience anything dispositive on this question, in either direction, nor has anyone ever presented me with any reason to believe that a god or many gods exist or do not exist.
