What can purely natural science tell me about my computer? Well, it can tell me many things that are interesting and might one day lead to a reproduction due to reverse engineering, but can and should it tell you that no intelligent design was involved? The obvious answer is a resounding No! But this answer comes from a brain that is far more complex than a computer and is currently attributed to purely natural science, i.e. mindlessness.

Show me your reasoning.
