AB,
It has to be a big no.
Wow. So to be clear, you expect others here to be open to the possibility of god, but you are not open to the possibility of no god.
Is that really the position you want to take?
Really?
Well, this is a discussion board. By your own admission, you don't actually want to discuss anything - rather all you're interested in is proselytising and no argument of any kind can ever be allowed to challenge your certainty about that. And that incidentally is pretty much the very definition of a closed mind.
Oh well. There is a faith sharing section of this mb - perhaps you'd be better off sharing your personal faith beliefs over there for those who like that kind of thing?
