Raoul has a point.
It's a matter of burden of proof. We've gone over this point a lot with the anomalists and others over the years.
It's not a matter of faith to not believe in leprechauns (not that I'm trying to draw an equivalence here between God and a leprechaun*, just picking an example out of my hat).
The guy running through the Irish woods with the butterfly net is the one who needs the faith. When he actually comes up with a faerie shoemaker, and exhibits it at the museum in a cage, then we start talking science. When the entire race of leprechauns ends up in sweatshops cranking out Nikes, we start talking economics.
But I digress.
