I had a catholic priest seminarist as a beginning boyfriend (sinner! was nice, though!) and went to his lectures with him and got into a discussion with the prof. I think we had to leave then even - for some strange reason, the guy didn't dump me, but wanted to transform theology after what I had said. Despite me not believing anything - I would have found out something important. Not exactly proof of god - but something almost equally impressive.
Forgot what that was supposed to be unfortunately.
