I believe that there is, but I'll have to let you know for sure after I get there, because as you said I can't prove it.
It's not a great way to look at it, but most people who don't believe can understand it this way. It's like hedging a bet. If I'm right I win, and someone who doesn't believe looses. If I'm wrong I still win, and maybe I helped someone along the way.
Just my twocents take it or leave it.
