Why Does God Need A Creator?

[NomenMihiNon]

the very notion defies logic.

You mean it defied physical laws. Perhaps you and he both missed the bit where this was a supernatural being doing the creating.

Okay, so if there is another, "supernatural" dimension in which God resides, who or what created that? Again, which makes more sense...the time and space which we occupy was created by an uncreated creator residing in uncreated time and space, or that our time and space is itself uncreated?

And if by definition the supernatural defies logic as your comment suggests, then either the very concept of logic is rendered meaningless, or the supernatural can be safely dismissed as illogical.
