Why the whole Adam and Eve Fall story makes no sense

[1994Californication]

God creates everything, including Adam and Eve.Adam and Eve eat from the tree of the knowledge of good and evil...the tree of knowledge (does that mean god wanted us to be stupid? Or just to mindlessly obey - I mean, is the "wrong" done here because they disobeyed, or because they gained the knowledge of good and evil) and then banished them from the garden, before they could eat from the tree of life (that would give them eternal life) - after playing a game of hide and seek.And its never explained why that tree was there in the first place or what was the deal with the talking snake(most Christians would say it was Satan but it was never explicitly stated as such).
