Kerry's got it right asides from the modern day comparisions
we have come to be God's knowing good and evil....
how the create and destroy.
Is a broad subject, nether do i think that it covers science. Since agreeing with two people that the leaves of a tree are green is science in itself. And God in that same Genesis created the world in order to see how we would name the animals and the trees. He asked us to discover and explore his world... and didn't forbid that.
the knowledge of good and evil, covers philosophy... putting human reasoning above God's given knowledge. The original sin is atheism, the atheist in all of us the counterpart of faith and obeyence wich we inherated all equally... the freedom to loose and gain faith... this same questioning we inhereted from Adam and Eve. is our mortal burden.
And Satan's rebellion in heaven is where the struggle between good and evil began. Not the original sin.
