sonnike,
I was waiting for that piffle to be trawled up by you. The fallacy of such an argument is that the 'design' is being altered independantly of the complete system. Ferrari don't take Lada's and shoe-horn a new engine in, they design a new car from the base up.
So, if I were a supreme being with infinite wisdom and power, I would create humans that don't need to eat or breath. But how is that possible you ask? Well I created physics, chemistry, the laws of the universe etc., so in my re-designed reality I can do what I want.
I'd also prevent hair-loss if I decide to put hair on any part of my new humans. And I'd separate sexual organs from urinary tracts. In fact, waste products are nasty, so I'll scratch that concept for a start.
Blood and guts? Nah, not in my human. Too messy. All they need is the air they breathe.
Of course, my nu-mans will still have emotions, all the senses, and still look the same (just so you don't think they'll look ugly). But because we don't need food, we don't need land, so we don't need wealth or have to do hard work. We socialise, and philosophise and love and make love in a clean, yet absolutely satisfying way.
Man, this designing is easy when you're absolutely all-powerful. God sure did mess up big time.
