Drich,
Not only did I read your theory - I recognised it.
I once came up with an almost identical theory in conversation with a young earth believer.
In the end it all comes down to whether Adam is dated from his creation or from the day he left Eden.
I couldn't get the young earther to accept that dating from the day he left Eden was the more likely.
From a scientific pov, however, there is simply no need for Adam and Eve in the story. They don't add anything and, obviously, there isn't a jot of evidence for them or Eden.
