''In other words, the Prime Creator required no previous Creator as a cause. AKA "The Prime cause of all causes requires no cause."
This breaks the very rules set by the claimant, that all complex systems require a creator.
A creator is a complex system, but now the rule is abandoned in favour of the personal belief of the claimant so the rule is broken in favour of a belief in a creator because it suits an emotional need of the believer.
If a creator can be eternal, so can a universe, so can life without a creator, therefore the rule imposed by the theist who says complexity requires a creator is meaningless, something cooked up in defence of a belief in god.
