Either way it seems to me that Adam and Eve being the first homo sapiens makes the most sense.
It makes sense to me and I’m open to it.
My appoximate date would be anywhere from 40,000 to 70,000 years ago, based on both Scriptures and science. This is totally speculative on my part, but that’s my best guess.
I’m also wondering too if Adam and Eve’s children didn’t go out from their own “original two” and marry with humans who already existed but who did not have immortal souls.
In this case, if true, it would mean that their marriage with these ‘other humans’ would breath an immortal soul into their offspring and then spread out further from there.
In this sense, the genetic diversity is
already present on a biological level. Plus, if true, it would simultaneously allow for the
transmission of original sin in addition to the
creation of an immortal soul from the primal parents of modern humanity-- Adam and Eve.
Perhaps Adam’s progency
transfiguring the essence of an immortal soul through conception from one generation to another generation is a parallel to Christ’s resurrection which allows us to be born again in the New Creation in Christ.
It would certainly add an extra dimension to these words…
2 Corinthians 5:17:
Therefore, if anyone is in Christ, he is a new creation; the old has gone, the new has come!
Perhaps, long ago, if anyone was in Adam, he was a new creation; the old had gone, the new had come.
