Q. Do you believe in a historical Adam and Eve? If one does, do they need to believe in a young earth?
Please see this post for my thoughts on whether Adam was necessarily a historical individual. In that post I observe, among other things, that “the Hebrew word ‘adam is used in an intriguing variety of ways in the book of Genesis, where it figures prominently in the opening narratives. Sometimes it seems indeed to be the name of a single historical individual, as in this statement: ‘When Adam had lived 130 years, he had a son in his own likeness, in his own image; and he named him Seth.’ But in other contexts (in fact, in the immediately preceding statement), the term refers more generally to humanity as created in the image of God. Note how ‘adam in that statement takes both singular and plural pronouns, and embraces both male and female: ‘When God created ‘adam, he made him in the likeness of God. Male and female he created them, and he blessed them and named them ‘adam when they were created.'”
In light of such considerations, I conclude that the Genesis narrative, and other Scriptures such as Paul’s arguments in 1 Corinthians and Romans about humanity being “in” Adam—the passages I address specifically in that other post, do not “require Adam to have been a historical individual. We need to make our mind up about that question on different grounds, and I think it’s fair and reasonable to bring scientific accounts of human origins into conversation with the Bible as we do so.”
But does someone who does conclude that Adam and Eve were historical individuals also have to believe in a young earth? I’m perhaps not the best person to offer a judgment about that, so let me just say that I know some people who do consider them to have been actual individuals but who do not believe in a young earth. Rather, these people I know are intrigued by the findings of anthropological genetic research that suggest that all modern humans are descended from a single female—someone scientists refer to informally as “Eve.” This does not mean that this woman was the only female human in existence at the time when she lived; the scientific perspective would be rather that her offspring survived while the lines descended from other early women died out. But these people I know suggest that God chose this “Eve” in some way to be the first bearer of the divine image, and so she was the first human “created in the image of God.”
Apparently all modern humans are also descended from the same man, although he didn’t necessarily live at the same time as “Eve.” Rather, once again, the lines descended from other early men would have died off while his offspring survived. I have no expertise in this field and for all I know the findings may have been updated since I last heard about them, so I would encourage you to search more about this topic if you’re interested. But the bottom line for our purposes here is that while I personally don’t feel that the Bible requires us to consider Adam and Eve to have been historical individuals, even if we do, that doesn’t necessarily commit us to a young earth.
