Heaven = Paradise
Paradise = Garden of Eden
Garden of Eden = Life without Knowledge
Life without Knowledge = Ignorance
so.....
Heaven = Ignorance?

"Ignorance is not bliss, it is oblivion." - Oscar Wilde

I've always had problems with the Biblical story of the Fall of Man. God makes man. Man eats fruit of knowledge. God gets pissed. Man gets tossed out on tuchis and loses eternal life. And this is so bad that every child of Adam henceforth gets smacked up with sin from birth.
Call me kooky for asking, but what was so great about the Garden of Eden? So, basically, Paradise is laying around naked, having no sex, and being a vegetarian. Little have we known, Adam and Eve were the first hippies. It was life of ignorance, without death, fear, or suffering. Again, what is so great about that?
If man knows nothing, how can we justify life as the precious gift of God? Adam and Eve walked with God in blissful joy. How blissful could man have been if he knew nothing, was challenged by nothing, and was untempered by mortality? Death and life are constant companions, which motivate mortals to express life and leave legacies. Not just by having children, man creates art, architecture, literature, and music. Knowledge drives man to want to know even more, and therefore experience the full complexity of God's creation, the universe. A sense of wonder is how we perceive the world and inquire how the hand of God moves in action....
