That's not evidence, that's just supposition.
There's no indication that nature can't produce beauty or order. Or that these aren't just concepts created in human minds that we then impose on reality via our perceptive framework.
It's not even related to the question being asked. Evidence for that would be something like this: "Single celled simple organisms (nee "pond scum") are incapable of developing into multicellular complex life due to [insert reasons here]".
This speaks to the problem. The two sides of this debate are, to borrow from Churchill, "two nations separated by a common language". I'm asking for evidence against 'A', you're telling me about how 'B' and 'C' can only be produced by 'X'. It's a non-sequitur. A deliberate one, I suspect.
When I ask for evidence, I'm seeking something that is demonstrable. Quantifiable. Able to be replicated.
If I'd never heard of a the Christian God before, why should I believe such a thing was responsible for 'beauty' or 'order' on earth? Or, to put it another way: How did you rule God in, and how did you rule nature out?
