Validity Of Adam And Eve As Humanity's Starting Point

I seem to respectfully abstain from that debate since, to me, the Bible seems reasonably interpreted as suggesting that Adam and Eve might have been the first two in the lineage of Israel, since the Old Testament seems reasonably suggested to be about the God/human relationship within the context of a sample group selected for the purpose of helping all humans better understand the nature of the human experience and its apparent dependence upon the God/human relationship.
