Hi Creationist,
You seem to be very reliant on interpretation here. This is puzzling, because the contradictions in Genesis are only a problem when it is held to be the literal truth.
For example, if I say "My dog is dead", there is only one literal interpretation, i.e. that my former canine buddy has ceased to enjoy oxygen. Of course, we could interpret what I said as allegorical, symbolic. Then you could read all sorts of explanations into the statement. But here we enter "words mean what I choose them to mean" territory. How would you know your interpretation was correct? I could have intended the statement to mean "I am sad" in a more general way, but since I left you with no way to know what kind of allegory I was using, you could never take "I am sad" as being a reliable interpretation. It is certainly not a literal interpretation.
If you choose to believe that the events described in Genesis really happened the way the text says they did, then there is a low limit imposed upon the amount of interpretation that one can reasonably apply to those texts.
To say that a story is partly literal, partly metaphorical begs the question "Which bit is which, and who decides that?".
Of course, if you allow the whole thing to be read as just an allegory, then the whole problem of contradictions in the text disappears, in a puff of logic.
