I think the human body is amazing... Everything is so perfect. Our earth is PERFECT, see how in nature nothing survives on its own, it uses another life to live. Everything works in sync with each other, the system of interdependance is so perfect, yet so fragile. I coud not have asked for a better planet. We have long arms and legs for reach, fingers to grab, hand that can slide and grip, a body of internal organs that function perfectly, but yet again very fragile. I believe that humans are not the most perfect beings, there are so many other animals which show som amazing qualities.
By no means did our god do a sloppy job... Or science for that matter.
