I can rephrase that then...
If a dumb black hole can create itself, and an intelligent God can create itself,
then surely, is it outside the ability of a Universe to create itself too?
Why do you need to shovel a God into the story that existed first?
The question of God is the question of order from chaos. Whether you give him a beard, a reversed time arrow, or simply the name "order" is a matter of framing and subjective assessment. Its simply a name you put on "nature" or rather the holes in our understanding of nature and our inserted guesses to these holes.
But the question is only being asked because your calling it him, and it has also been called a being in the thread by Roundy.
That implies that an intelligent thing created itself, and then created lesser things.
It seems less complicated for me not to introduce the word God unless talking about an intelligent being,
or to accept that it's simpler for the less complicated thing (the Universe) could have come about by natural occurrence
than the more complicated thing (the intelligent God being, who then went on to create a universe).
It occurs to me that any story with "God" in it can be abbreviated to make it more plausible, by taking the "God" out of it.
