Rev, Why would you think I was having a bad night? I answer the questions people ask me and I'm always fine, but thank you for caring. ;o)
//until we come to common agreement on what constitutes the concept of god we can't debate the possibility of it's existence.//
I disagree. You're never going to get common agreement because, as you rightly say, people have conflicting views. However, if we cease to debate it for that reason we will never find the answer. Additionally, no one knows what god - if it exists - is, and that surely is part of the great debate.
//I couldn't draw a universally recognisable picture of god.//
You might not be able to, but several artists including Michelangelo have managed to produce images that are pretty widely recognised - hence your description of the Abrahamic god on another thread as 'Old Beardy'.
