Its arguments are all fallacious. It says the universe itself proves a god and then goes on to mangle and simplify what we know about physics and the big bang: That at the quantum scale causality breaks down so no first cause is necessary - and that the laws of the universe were structured different so as to allow many odd things. It is much simpler, says Ockham's razor, to suppose that the universe made itself when physics implies that it could've, or if that doesn't do it for you, that instead of invoking a unnecessarily infinite and intelligent first cause, invoke one with the only requirement: that it doesn't itself need a cause (again, not important because of quantum physics.)

It than cites prophecy as the main evidence of Christianity, without acknowledging the explanations of vagueness, pattern seeking, inevitability, self fulfillment, and retrodiction. It also doesn't acknowledge the apparent prophecies of the Greek oracles, or the Koran, or individuals like Nostradamus (who Christians presumably reject for the same reason's I reject the bible's prophecies.) There is the other issue of innumerable unfilled prophecies that Jesus never did as promised in the Old Testament, and which keep many Orthodox Jews in anticipation for the true messiah.
