For Zakath to be successful in this debate he will have to give compelling evidence that everything that exists from the universe, to our solar system to the first cell to the human being could come into existence without help from a supernatural force.
Or at very least Zakath will have to give us a conceptual idea of how this might have happened.
So far, he has failed miserably.
In my opinion Zakath is making the same mistake in BR VII as he did in BR II. It seems he wants to use these battles as a means to mock the Christian God. But neither BR VII nor BR II hinge upon Christianity necessarily.
It's logically possible that a god could exist that wasn't the God of the Bible and absolute morality could have been set by another god.
I feel like Zakath cannot get over the fact that he just can't mock the Christian God and therefore he really doesn't have much ammo.
