This quote sums up my feelings perfectly:
... No matter how many fine and fancy meanings we may be able to draw out of [Adam and Eve's] historicity, it must also have a plain meaning: somewhere along the line, some people had to have shown up at a real time and place as the first of a race of priestly beings.
I feel I am about to lose my audience. I shall give you one disclaimer. I am not at all concerned here with whether those people were a lonely he and she, or a crowd, or whether they were made in one shot or gradually pasted up over millions of years. The only point I want to make is that if you seriously intend to see history as a real web, then the web itself must have a beginning, and that beginning must be discussed historically. No one should be exempted from the attempt to write Genesis; and no one ever is. Admittedly, neither scientists nor theologians have reporters' notes on the event, so everybody has to do the job imaginatively; but it is precisely that job that everyone has to do, scientists as well as theologians. There is no real choice about Adam and Eve. The only open question is whether we will do them, and the rest of history that follows from them, justice.
I bring this up because a great deal of solemn nonsense has been bandied about on the subject. In the interest of making a hasty accommodation between a stale biblical chronology and a half-baked theory of universal evolution, all kinds of things were said by all kinds of people. On the one hand, biblical obscurantists made a frantic attempt to salvage the chronology by sweeping scientific knowledge under the rug. On the other, modernist theologians retreated so hurriedly before the specter of evolutionary supersession that they abandoned wholesale the theology and horse sense of the Scriptures. The first have, mercifully, met the fate they deserved; but the second are still with us. They have such a fear of sounding like Genesis that they end up sounding like gibberish. They are so afraid of making Adam and Eve particular human beings that they forget that, if history is real, some particular people will have to turn out to have been Adam and Eve. In the day of judgment we may find out that they called each other Oscar and Enid and that they lived on a Norwegian fjord; but those will be only details. They themselves will have existed. And the essential historical fact about them will be not simply that our biological inheritance came from them but that all the threads of the web began with them. It is precisely the rest of history that you lose if you unload Adam and Eve.
