To go strictly by the historical events/dates, the Christian God is more credible then Islamic God (Although Judaism supersedes both in terms of dates )thats debatable. in 2013 im pretty comfortable saying that we would be better off with nobody believing in god
no one knows the right fukkin answer anyway NO ONE will address that either muslims or christians have to be wrong about jesus. so even if there was a god, most of you fools are still participating in an exercise in futility
