For example why would Edison not be a capable creator of the light bulb? Furthermore who would argue that Edison was not intelligent?
Genius is one percent inspiration, ninety-nine percent perspiration - Thomas Edison
Edison was an intelligent creator, but there was also a substantial "trial and error" component to that creativity. To find out what works, one must also find out what doesn't work. He had many great successes because he was willing to also have many great failures.
Evolution is apparently a "trial and error" process (theistic evolutionists and IDists may disagree). Statistically, the bad ideas are weeded out and the better ideas have a chance to be further refined. Now, a powerful God would indeed be able to tighten up the efficiency of evolution. Or he could achieve the ultimate in efficiency and instantly create everything out of nothing.
