You're not an atheist, you're a deist. Just saying.
Anyway, for an atheist like me, a gap in knowledge and just substituting "God" into this gap doesn't do it for me. We don't know what happened to create the universe and maybe we never will, but saying "God did it" really has no basis in any evidence and I could just as well make any other claim as to how it came to be that is completely unfounded and it would be just as valid.
Your theory also begs the question: how did this creator come to be? And if he is inexplicable and doesn't need a cause, then we haven't really gotten anywhere.
