Obviously, this is a very invalid example and you cannot consider deseases an mutations as bad design. Just what do you want God to do in order for you to admit intellegent design? Create a life for humans with absolutely no diseases, no body gets tired or hurt, nobody experiences unfortunate events, nobody dies and everyone is immortal and lives forever in a happy utopia?!! This kind of perfect life is only in paradise and not in the worldy life. This life is intentionally designed with some difficulties and harsh conditions, and diseases are part of these difficulties and they do not constitute examples of bad design. I am sure that you still wont understand what Im saying since you dont believe in God in the first plance.
Ah, the old 'how would you understand it, you`re not a believer' nonsense.
Au contraire, I think diseases are a very good example of design. So effective, so difficult to cure, some even have a near 100% mortality result. Can`t knock that kill rate. Just what you would expect from a kind, loving God. One that gives you freewill. Must have come as a shock to believers who saw their babies and children die in agony before experiencing all that Godly Love. Let alone freewill. But 'Intelligent'? I think not.
Immortality? Let`s see what we have to fight before we add the disease overload:
Gravity
Solar radiation
Toxic plants
Toxic minerals
Gases, like radon, Co, Co2, methane, etc.
Environment--heat, cold, drought,atmospheric contamination (and not from Man)
Natural Events (Acts of God)floods,famines,earthquakes,eruptions,tsunamis,tornados,hurricanes
Predators--animal,reptile,insect,marine
Bacteria-on and within our bodies (was it 213 species at last count?)
Parasites--fleas,ticks,leeches,flies,mosquitoes (all lining up to carry disease),tapeworms and their wriggly relations, flukes
Fungi
If it stung, bit or consumed, God lined them up.
But of course, God wasn`t content with that little load, He had to add the diseases. Not just any old disease. No, He specialised in crippling, eating, maiming, blinding, fevering,painful diseases. Lifetime diseases. Fatal diseases. Like any self-respecting Designer would do.[/switches off irony]
