The serpent ( the beautiful winged creature) asked Eve a question.  Eve listened.  Then she answered:

Gen. 3:2-3  "And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:  But of the fruit of the tree which is in the midst of the garden,  God hath said, Ye shall not eat of it,  (she should have stopped right there) neither shall ye touch it, lest ye die."

I guess Adam told her about the tree.  (Remember, Eve wasn't even created when God told Adam about the  trees.)  I guess Adam told her they were not to eat the fruit from the tree of knowledge of good and evil, or they would die.  Did Adam tell her that it was the tree of knowledge of good and evil?  Or as Eve told the serpent, it was "...the tree...in the midst of the garden."   Either way, she knew there was a specific tree in the garden from which she wasn't supposed to eat.

Were they standing by the tree?  Or did she follow the serpent to where the tree was--further adding to the first thing she did that was wrong--listening to the serpent?  One step at a time she was allowing herself to be led into temptation.  We do the same thing.  We listen.  We turn.  We look.  We touch.  We take a first step in a direction we ought not go.  One step at a time, we sin.  We do the thing God has told us not to do.

Then she did something that women (I'm a woman so I know how this goes,) seem to have particular difficulty with.  She made the story better.  She added something to the story to make it more dramatic.  She said "...niether shall ye touch it, lest ye die."  God didn't say that.  I don't know what Adam said.  Did he add the part about not touching it?  Or did Eve come up with that on her own?
