re: Well put.
"There is no such thing as nothing" should be the primary postulate of any rational cosmology.
It's kind of like applying the Copernican Principle to the universe. The universe is not in a special state called Existent as compared to Non-existent. There is only existence - therefore no need for a creation (devine or otherwise).
With apologies to Billy Preston:
"Nothin' from nothin' leaves nothin'
but you gotta have somethin'
If you wanna BE with me"
