The Pagan battle cry needs to be "We're all just here by mistake!"
That'll go over well 
Well, we ARE here by mistake. At least according to your religion. First, the all powerful and all-knowing god made a creature whose actions he could not foresee in the unfortunate apple-incidence in the Garden of Eden, and he thus punished his own creation for itīs actions. Donīt you think he should take a bit of the blame himself, being all-knowing and all-powerful? Shouldnt he know in advance what would happen?
Further, the god tired with his creation and almost killed of all of it in the great flood. He also punished mankind after the tower of Babel incident, creating linguistic confusion.
It seems that this god of yours is quite human-like, vindictive and irrational... ;-)
