According to traditional Christian theology, Adam and Eve were the first human beings. There were no pre-Adamites. Theistic evolutionists usually disagree on scientific rather than exegetical grounds. About the only exegetical argument one runs across to challenge the traditional view is the claim that Cain's fear of retribution (Gen 4:13ff.) implies the existence of other human contemporaries (besides Adam, Eve, and Cain's late brother).





Now, there are multiple problems with that inference, but for now, let's grant, for the sake of argument, that this solves the alleged problem of Cain's statement. That solves one problem by creating another.





If Adam and Eve were not the first humans, then why did God make a wife for Adam? if there were other humans on the scene, why didn't Adam simply take a wife from one of the many eligible women already in existence? The theistic evolutionary appeal to Cain's statement implies the availability of other women. Why didn't Adam get a wife the way Isaac got a wife? According to theistic evolution, as well as the theistic evolutionary interpretation of Gen 4:13ff., there were plenty of women to choose from. So why does the narrator depict God specially creating Eve to resolve Adam's lack of female companionship.
