The modern bible makes it sound like Jesus and God are somehow the same thing. Probably to get around the dilemma of believing in the Old Testament which says "have no other god before me" while simultaneously worshiping Jesus instead of God.
As far as the tree of knowlege goes, if God didn't put it there, who did? and why would he intentionally tell them not to eat it? Wouldn't it have been better to just snap his fingers and make the tree go away?
Adam and Eve didn't have "knowledge" at the time, so they presumably had the mental capacity of the average toddler (having no concept of nakedness), so God basically performed the equivalent of placing a cookie jar in front of a 2-year-old and then telling the 2-year-old not to eat any of the cookies. I would expect the creator of the universe to be a bit smarter than that.
Now, you could claim that it was Lucifer that created the Tree of Knowledge in order to trick us, but that would contradict other parts of the bible that say Lucifer has no power to create anything.
Basically, either the Bible is wrong, or God is a complete moron who should have known better.
