I don't see why you believe "God did it" is an easy answer. "I don't know" is much easier. Evolution could very easily produce an "I don't know." How can evolution produced, "God did it." And if evolution did produce, "God did it." Then very likely he did.
Evolution is about genetics. That we can think at a higher level and organize complex societies in partially negates the effects of evolution. On a simple level, the weak are no longer are left to die out; someone being born with a genetic defect in his leg not allowing him to escape predators can easily thrive in human society and pass on his genes.
