Christians and UNSURE people of their beliefs COME!?

Iam agnostic so i don't need the preaching but i hope you understand that the faith religious folks have no matter how unrealistical and illogical it is are not going to budge even if what they say at you tube was true. No matter how much logic is tossed to religious people they are never going to accept it, So don't get to disappointed which the answers you get.
