Whoo hoo!
Can I be the first Agnostic to reply here?
I believe that one of the hardest things for people to ever admit is, "I don't know!"
I'm a programmer, so of course I work with lots of other programmers and other random smart people. For those of you in a similar situation, you can probably relate to this... If you ask MOST people how to do something, how something works, or any other question like that, you're bound to get some sort of rambling of what they 'think' or how it 'possibly' could work. What you'll RARELY get is, "I don't know, but maybe..."
I think this carries over to religion pretty easily, and is why I'm agnostic.
I don't know the truth, and I don't believe that anybody else does. I don't believe the Bible is anything more than a mistranslated collection of stories written a long time ago, but that doesn't mean I completely don't believe in some higher being... but heck if I know what that being (if it exists) is all about.
Some will say, "You just have to have faith!!"
I'm still a Bears fan, I think that demonstrates my ability to HAVE faith
