1. Readers of this article may wish to know of my stand on evolution. I was a convinced evolutionist before I got to know Jesus and became a Christian, and I have remained one on both counts. I studied zoology in the University of London before I did biblical studies at Regent College.
2. This way of thinking about history arose out of the Enlightenment, when human reason was raised to the office of final arbiter of what is truth, and that what is truth must be open to empirical investigation, the evidences subject to the senses (seen, heard, weighed, measured, etc).
3. Outside of Gen 1-4, Eve is mentioned only in 2 Cor 11:3; and 1 Tim 2:13, while Adam is found at Gen 5:3-5 (3x); 1 Chron 1:1; Hos 6:7; Lk 3:38; Rom 5:14; Rom 5:14 (2x); 1 Cor 15:22, 45; 1 Tim 2:13-14 (2x) and Jude 1:14.

(http://biologos.org/blogs/dennis-venema-letters-to-the duchess/does-genetics-point-to-a-single-primal-couple.). A popular exposition of how the conclusion is arrived at and the significance of the conclusion for understanding Genesis is explored in Dennis R. Venema and Scot McKnight, Adam and the Genome.

5. Dennis R. Venema and Scot McKnight, Adam and the Genome. Reading Scripture after Genetic Science (Grand Rapids: Brazos, 2017). E-book, Chap 6, p131 of 139. McKnight key word for Adam and Eve is that they are 'literary' and 'genealogical.' The first means that we know of them only from the text, the second in the sense that Israel consistently traced their lineage from them. I doubt that either ideas will make much sense in a sermon esp., for an audience that is not higly literate.
