Hmmmm... I must say I do beleive there is some greater spirit, but I couldn't write it down. People's faith is one of the hardest things to describe as it's personal, but also very organic and instictive.
I personally aren't Christian but many critics of the Bible point out that it is condradictory which may be true. Most people though believe that the Bible is more of an analogy and to fit something as complex of faith into something that equates to a selection of short stories is very hard. I doubt most people believe the universe was created in 168 hours, it's just a kind of metaphor for belief.
So basically the answer is yes but I don't think he's an old man with a beard
There used to be a real me, but I had it surgically removed.
