You: In nature there are many things which, at first glance, seem to show signs of design, but that doesn't prove that they were designed. For instance, there are perfectly natural processes by which crystals and snowflakes are formed, and science can describe these processes.

Aaron: It is true that science has a ready explanation, but your very example proves my point! The fact that snowflakes are so beautiful, so organized, is proof that God's hand is in the works. What more could you want?

You: I could want a new topic of conversation; we've beaten the mathematical perfection of nature to death.
