To answer this question would require a deep knowledge of what
is really meant by 'Tree of Knowledge'.
Do you know what is 'Tree of Knowledge' ?
By the way, I think it's Fruit of Knowledge, not tree. Adam didn't
eat the leaves and the branches, did he?
Personally, I have always been intrigued by it.
My opinion, this knowledge of what is right and wrong, and what is
shame and so on, has made humans to enter a different realm and
therefore humans are sent to earth.
This is only my fague view, since I think the concept of 'fruit of
knowledge of right and wrong' is deeply symbolic and has profound
meaning, which Im not able to decipher what it really meant.
