It's hard to beat William Lane Craig for conservative evangelical credentials.

This influential author and philosophy professor teaches at Houston Baptist University, where faculty members "must" believe in the Bible's divine inspiration and "that man was directly created by God." He's simultaneously a visiting scholar at California's Talbot School of Theology, where teachers commit to the beliefs that the Bible is "without error or misstatement" in its "record of historical facts" and that Adam was created by God and "not from living ancestors."

Craig is also a longtime member in good standing of the Evangelical Theological Society, whose members are required to affirm that the entire Bible is "the Word of God written and is therefore inerrant" as originally written. Trinity Evangelical Divinity School, where he formerly taught, likewise proclaims that the Bible is "without error."

But exactly how do those vows apply to the early chapters of the Bible's Book of Genesis?

Debates about this issue are frequently hooks for news stories, energized over and over again. Evolution and the creation of Adam and Eve have been allergic issues among evangelical Protestants in the 162 years since Darwin published "On the Origin of Species"?

So there's eye-opening stuff in Craig's article titled "The Historical Adam" in the current First Things magazine.

In Genesis 1-11, he asserts, those "fantastic lifespans" of primeval humans starting with Adam indicate "we are not dealing here with straightforward history."

Yet it's not simple fiction either, but rather an amalgam he calls "mytho-history, not to be taken literally," though there could be some overlap between the "the literary Adam of Genesis" over against the "historical Adam." He further explains that in the New Testament, Jesus and Paul were talking about that non-literal "literary Adam."

Given current science, Craig figures Adam and Eve lived 750,000 to a million years ago at the point of separation between Neanderthals and our own species of homo sapiens, with the latter endowed by God to surpass human-like animals that lacked rational thought. On that understanding, "the mythic history of Genesis is fully consistent with current scientific evidence concerning human origins."
