Proving the Bible is false in few words.

[fr0d0]

Oh...so you don't believe that god is omnipotent then.

Yes I do. Omni potent doesn't mean impossi potent. See our excellent debates on the subject here : http://atheistforums.org/forum-25.html

Just out of interest, is there any particular reason for your thinking that god can't lie?

Yes. From the first conception the idea of God is a separation of good and evil. As a positive effect, God is defined as wholly good. This is the Christian concept.

The Tree of the Knowledge of Good and Evil is a different tree, that's the one they were denied access to, but chose to anyway - once tasted, never forgotten it seems.

How would they have known it would be evil to disobey God, until they had knowledge of good and evil by eating the apple?

All they knew was that it was forbidden. The snake lied to them telling them it would be good for them. they knew it was wrong because they were ashamed when they next met God.
