The Problem With the Aristotelian Proof

Phaser argues that even timelessly existing things are actual and involve a kind of timeless actualization of potential. If the universe can be timeless, but still require an actualizer for its potential existence, then why doesn't a timeless God require an actualiser for his potential existence? The answer is that a block universe has a distinction between its essence or what it is and its existence or that it is. So there must be something beyond the universe that actualizes one of those potentials over the others. But while in the block universe, there is a difference between essence and existence, which leads to only some essences of the block universe having existence. In God, there is no difference.
