Due to the mention of farming, livestock, tents, stringed musical instruments and artifacts made of copper and iron in Genesis 4, Adam has credibility as a real-life, historical individual living in the Neolithic (10,000 to 3300 BC), or at the beginning or the Chalcolithic Period, but there is no possibility he could have been the biological progenitor of the entire human race since Homo sapiens have a 200,000 year history. Genesis tells the story of biblical peoples some of whom were ancestral to the Messiah. And the story, indeed the lineage, begins with Adam.
