If you are at peace with your belief that this intricately complicated universe came from the hand of an omnipotent diety you read about in a book, and whose existence you can't prove, then I feel perfectly comfortable with my belief that it came from, using your terminology, a 'space fart'.
So.. What garbage can did God fall from?
My point is that once you start trying to "prove" things like creationism with science. Then you open up the question of trying to affirmatively prove God. Which is impossible.
The smart idea for faithful people is to recognize there is no conflict between Genesis and science.
There are two stories of creation in Gensis, and you can reconcile the two by reading between the lines. But once you establish that you CAN read between the lines, then you can reconcile evolution with Genesis too.
