Are all children the same or are some smarter than others?
Life must come from life. I am not saying that offspring may not be smarter than parents. What I am saying is that the forces of nature are incapable of producing life. Even seeds must come from a plant, they do not come from dirt. The wind will move dirt but is incapable of producing life.
An intelligent cause will produce a intelligent effect. An non-intelligent cause will produce a non-intelligent effect.
