A case for Natural Design

Out of curiosity, do you know of any thing in nature that is a nonfunctional construction?I understand what you are saying about the human eye, but is the entire human being a functional contruction?IOW, the parts of a machine each have a function, but what is the function of the machine itself.If the machine serves no purpose, wouldn't that demonstrate that there is no underlying plan?I'm not a scientist, so take what I say accordingly.

So we have reproduction as a function of the human machine. The human machine also consumes resources.So our machine consumes resources, produces waste and reproduces.Is the function of our machine necessary to the overall planet or nature?IOW, if our machine is removed from the picture, would any other part of nature then cease to function? I would say no. Actually nature would probably be better off without our machine.Our machine doesn't appear to have a function necessary to a larger planetary view.Is there any part of nature that depends on the function our machine provides?

As I said I'm not a scientist so I tend to forget about that which is invisible to my eye.We have parasites and bacteria that live on or within us. Did these only come to exist after mankind developed or did they exist in some form before.IOW a brand of parasite or bacteria which fed off something else evolved to feed off of this new human machine. If humans die off the parasites and bacteria would probably evolve to feed off another creature. If they don't evolve, then yes they would die out, but does that negatively impact nature overall.So maybe the true function of living machines is to survive by whatever means necessary. No underlying plan on how or when, just however or whenever they manage to adapt. If they don't adapt, they don't survive and are gone like the Dodo bird.Of course this being in the science forum, I'm sure the scientists prefer to discuss with the big words and microwhosits, but wanted to try a hand at a very simplistic view. Simple science.Thanks for talking with me.
