Considering I agree with you, this might be a pointless response, but I'd take it one step further. To my mind, complexity negates a creator. If you want to design something, the simpler the better. There are much less things to go wrong or need fixing if the design is simple. That's sort of the premise behind KISS (keep it simple stupid). However, complexity would be a necessity if evolution is true. Adding things on to already existing things makes it more and more complex, though not necessarily the best "design" one could make to overcome whatever obstacles are being faced.
