And the Lord God commanded the man, "You may freely eat of every tree of the garden; but of the tree of the knowledge of good and evil you shall not eat, for in the day that you eat of it you shall die...(Genesis 2:16-17)

Interesting thing here is that God is talking to Adam, the man, before the woman was there..
And his punishment(?) for eating the tree is death which is kind of odd considering God just created the world and no one tasted "death"; the only human being, Adam, hasn't died. That means Adam might not know the meaning of "death". So, at this moment, God is telling Adam (not Eve) not to eat of the tree and the consquence of eating the tree will be "death", which Adam might not know the exact meaning of.

Now the serpent was more crafty than any other wild animal that the Lord God had made. He said to the woman, "Did God say, 'You' shall not eat from any tree in the garden'?" The woman said to the serpent, "We may eat of the fruit of the trees in the garden; but God said, 'You shall not eat of the fruit of the tree that is in the middle of the garden, nor shall you touch it, or you shall die.'"....(Genesis 3:!-3)

Eve is lying. God never told her not to eat the tree but he told Adam. And she's sayng that God told us...If God never told Eve about the tree, it must be Adam who told her not to eat the tree...

Anyhow serpent goes on and says 'you'll not die even if you eat the tree..but you'll be like God...'. Eve doesn't know "death" either. I mean, we're talking about the Garden of Eden, the perfect world where there's no death. Then how come "death" be pushiment where no one heard of death so no one knows about death? Do Adam and Eve know death? If they do, how did they found about death? Did God implemented the concept of "death" into his very first humanic creations (Adam and Eve)? Even though he didn't plan to have orignial sin creeping into the Garden of Eden?

Maybe God planned, knew,..or whatever-ed everything. He some-verb-ed that our first human ancestors will sin and "death" will come upon the Earth...
