Though I do believe there was an actual tree of the knowledge of good and evil in the garden I also think that in many ways it represents the human tree of progeny. The knowledge of good and evil wasn't so much about personal knowledge per se but the knowledge of having been the producer of good and evil decedents, a knowledge that only God could safely possess. God had not given Adam and Eve the permission to freely reproduce according to their physical nature, when they took it upon themselves to do so, they obtained the very sorrowful knowledge of what it was like to have spawned evil, though not of their intention.
Their own son Cain murdered his brother, this was the knowledge God never intended them to have. Powerful evidence for this is the fact that among the immediate consequences of this event was their sudden awareness of their nakedness and subsequent cover up. Humanity to this very day covers it's nakedness, a singular phenomena among all nature.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
