Never thought of that. Thanks.
There are some problems with this view. They pretty much all stem from the fact that if Adam isn't the father of all then we were not all condemned by his failure in the garden. It snowballs from there.
I don’t want to seem like a biblical know it all....but, on the sixth day god created male, and female in his image..some were hunters, fisherman, and farmers...on the eight day god created adam from the dust of the earth..he needed a gardener for eden ,,through adam,and eves bloodline our lord jesus was born,,satan had been trying to disrupt that blood line to prevent christs birth,,he knew once Christ was born,died , and was raised from the dead by our father..he was doomed..christs victory,,satans judgement for eternal damnation.....cain married in the land of nod to someone from the 6th day creation..also he is not listed in adams family tree..because he wasn’t adams son...he was guess whos son?
