I came here to mention this, and note that this is an excellent way to start conversations about anything controversial, including politics and religion. If I'm interested in having that argument, I usually start by saying:<p>"One of us is clearly wrong, and there is a chance that it's me and a chance that it's you. I can give you a list of events that can happen or points that you can prove that will cause me to change my mind entirely and agree with you. What's your list?"
