Genesis 1-3

1:27
In this verse, God is referred to as "He".  As far back as history records, humanity has been almost entirely male-dominated.  This explains why God would be conceived of as male, but such a paradigm implies inherent male spiritual superiority.  The "superiority" of males has never been proven, and not for lack of trying.  Through observation of nature (where both male and female dominance can be found), or through the dictates of logic and reason (which show all humans to be basically alike in intelligence and capability), there is no justification for the notion of male superiority.  The impartial "eyes" of God could not view gender as a sign of lesser or greater worth, and the notion of God being male is so obviously flawed and provincial as to be unworthy of consideration.

According to verse 5, Adam and Eve did not possess knowledge of good or evil before they ate of the tree.  Yet they were punished for choosing to eat of it.  If they were not capable of distinguishing good from evil, it is preposterously unjust to punish them.  Also, observations of serpents reveal no abnormally malicious subtlety, nor any uniquely "evil" characteristics, therefore it seems unreasonable to attribute to them these traits.
3:22-24
Assuming that the tree of life exists, and we never hear of it because all die who see it, it shouldn't be hard to at least prove it's possible existence, and thereby begin to verify the veracity of the Bible. First one must locate the general area of the tree by finding the one spot on the earth where people go, but never return from (Palm Springs doesn't count). Then march a single-file line of people into that area. When screams of death come from the front, give orders to turn back. The people remaining would describe what they experienced. Anyone truly seeking to prove the truth of the Bible could have done this centuries ago, yet no one's bothered. Hm.
