I thought you being sarcastic again, moghrabi. Anyway, if-if-if ... I'm a rational person and I want proof. That's why I also don't believe in God ... You could also say: why do you believe in what happened on 9/11 - which could be a good question. I guess so far there's no good alternative, and it's better to discuss this with people who are not convinced about the official story of 9/11 than with people who are, not?
