I saw an interesting analogy for this reasoning. I think it was in
Last Chance to See by Douglas Adams. Imagine a puddle of water in the ground wakes up and contemplates its environment. It notices that the hole it is in is the perfect shape to contain it. That hardly seems to be likely enough to have happened by chance, so the puddle concludes that the hole was dug especially for it.
Evolution is the process by which life adapts to fill its environment. Life that more perfectly meshes with its environment (including other life) is more successful. So intricate, perfectly balanced dependencies end up appearing.
This isn't to deny that it is possible that evolution is directed, but the intricate dependencies don't imply it.
