I was thinking about that just the other day. If God is perfect, then he can only create perfection. If he created perfect animals (and people) then they wouldn't grow old and weak and then die.
Someone might argue that God intentially created animals to die. Why? Why would a prefectionist create something to fail?
The WTS teaches that man was supposed to live forever but by sinning lost everlasting life. The Genesis account does not say anywhere that man was to live forever. In fact, God expelled man from the Garden before he could eat of the tree of everlasting life. Why would that tree be needed if man already was to live forever?
If God is perfect why did he invent evil? If God is perfect, then how did he create a creature that became Satan? God created Satan, therefore he created evil. People want to say that God gave his intelligent creatures free will. Fine. But if intelligent creatures were perfect, then they would always make perfect choices. If Eve was perfect, why was she so easlily deceived? A pefect person would not have been deceived.
If God is perfect, why would he allow evil to exist? He created Satan, Satan turns bad. Pefection 0, evil 1. The perfect God does not destroy this imperfection right away but allows it to continue. Perfection 0, evil 2. Evil then turns "perfect" man into "evil". Perfection 0, evil 3. "Perfect man grows old and dies". Perfection 0, evil 4. Mankind ruins the earth and wages war, killing millions. Perfection 0, evil 5. On and on it goes.
Who created implements of war? Evil or Perfection? Perfection. God drove Adam and Eve out of the Garden of Eden and had the entrance guarded by angels and a flaming sword. Why a sword? Why was a war instrument needed to keep two naked people out of a garden?
Point is, the whole creation bit and Garden of Eden bit with snakes and deadly fruit is all fairy tales. JWs and many other fundamentalists buy into it.
