Hi Dennis, you and Dr. Gauger may not be so far apart on the science. She has, after all, stated that the hypothesized 2 individuals would have lived several hundred thousand years ago–in the H Erectus time frame.
That said, I fail to see how the hypothesis would provide even faint support for the theological assertion that all of humanity is descended from the Biblical Adam and Eve. The reason is that Genesis portrays Adam and Eve as agriculturalists. And the practice of agriculture goes back no more than 10,000 years.
Grace and peace,
Chris
