Well, the anthropomorphism and the rather simplistic analogies ("a painting needs a painter, so those natural water crystals must have been designed by an artist as well - all hail the Snow Queen and her crystal-manufacturing court!") should be a strong indicator in and of themselves.
I am not discounting the possibility that this universe was "created", or that there could be entities so intelligent and powerful that we are little more than amoebae by comparison. But "God" is conceived as a person by the very definition of the term, and as such strikes me as little more than Man projecting himself upon everything, as he is wont to do.
Just look at how myths all across the globe operate: people see an unusual rock formation, and they instantly declare that it's the remnant of an artificial structure made by giants, gods, elves, or what have you. People detect patterns in nature (annual floods, rainy season, etc.), and they instantly attribute it to a human-like intelligence orchestrating events, sacrificing chickens to the "river spirit" to please spare their village. People see one family succumbing to a particularly bad case of influenza, and another remaining uninfected, and they attribute it to supernatural moral judgment, with the deceased family *clearly* being guilty of some misdemeanour while the spared ones are equally *obviously* exalted for some extraordinary virtue.
