Anthony - excellent questions, each one can spur debate and have in the past on this forum, so I hope you find the forum helpful.
I would like to propose my theory (recently presented at the ASA National Conference) that Chapter 1 and Chapter 2 of Genesis are sequential which I believe eliminates the conflict with evolution and eliminates many contradictions if the two stories are to be taken as a retelling of the same events. I would ask you to reread Gen 1 & 2 with this in mind. I believe evolution is the mechanism God choose to guide life to its current outcome. Evolved man was created in chapter 1 in God’s image with a mind, soul and the ability to determine right from wrong, and God saw that it was “good”.
The creation of Adam, Eve and the Garden was a creation specific to the garden (there is nothing to indicate otherwise) and through Adam’s sin, sin entered the world. Paul indicates the Jesus is the antithesis of Adam (Romans 5 and 1 Cor 15) which indicates to me that Adam would need to be a historical figure.
I would be interested to hear you feedback on the above prior to tackling other points. The feedback I received in the ASA conference what that it is well accepted that Gen 4 is evidence that others existed at the time of Adam & Eve, where I was using Gen 6.
