I do secretly want a girl, but I'm pretty sure it's a boy. :)
As for natural complexity, I see it as nothing more than evidence of its own existence. To humans, what we invent and create is complex. I don't think it's fair to extend the same definition to what some people call "natural complexity." Until all natural reasons have been exhausted, I see no reason to turn to the supernatural.
Ah, yes, I do know what you mean about the beauty and awe inherent in physical reality, but that is not evidence for a creator; it's simply evidence that humanity has come to view its environment as beautiful and accommodating. In other words, it's evidence that humanity can adapt to its environment. I've yet to see anything empirical to even indicate a god--any god--exists. Until there is reason to believe a god exists, there is no reason to believe.
