because the first humans are not created to know everything..
the tree of knowledge is meant to be the tree of all knowing..
once you eat it, you'd be aware & knowledgeable of everything.
which Adam & Eve arent capable to handle yet..
there's another verse in the bible that states
"increased knowledge is increased sorrow"
which is the exact opposite of "ignorance is bliss"
but the 2 quotations are quite complimentary.
knowledge arent suppose to be taken in an instant,
like LIFE, it's suppose to be a journey...
something to be Learned gradually.. step by step...
so always remember the fruit of knowledge is Bitter,
only if reaped at the wrong time, when it's still UNRIPE.
but the Fruit is the sweetest,
only with Patience to let it Grow in it's properTime.
