From Tremper Longman, at BioLogos:

The description of how Adam was created is certainly figurative. The question is open as to whether there was an actual person named Adam who was the first human being or not. Perhaps there was a first man, Adam, and a first woman, Eve, designated as such by God at the right time in his development of human beings. Or perhaps Adam, whose name after all means “Human,” is himself figurative of humanity in general. I have not resolved this issue in my own mind except to say that there is nothing that insists on a literal understanding of Adam in a passage so filled with obvious figurative description. The New Testament’s use of Adam (Romans 5 and 1 Corinthians 15) does not resolve the issue as some suggest because it is possible, even natural, to make an analogy between a literary figure and a historical one.

This issue is an important one. It is wrong to challenge people to choose between the Bible and the science of evolution as if you can only believe that one or the other is true. They are not in conflict. It is particularly damaging to insist that our young people make this kind of false choice as they are studying biology in secondary school or college. If we do so, we will force some to choose against the Bible and others to check their intelligence at the classroom door. This is a false dilemma created by a misuse of the biblical text.
