Pondering Angels Dancing on the Head of a Pin
Victor Reppert asks "If God used an evolutionary process to create us, why did he do it that way?"
My response:

This argument is taken from James Blish's "A Case of Conscience."
Did Adam have a navel?
One could easily say, "of course not." The navel is the evidence of a particular human's human past, namely having had a mother, which Adam lacked.

Yet, all of the great artists have painted Adam with a navel. Are they wrong?
Maybe not. Adam was an archetype and prototype of the human being. Moreover, Adam was created with all proper human perfections and traits. Human beings have mothers as a trait and perfection that is properly due to the condition of being human. Therefore, in some sense, an Adam without a navel would have been less human than his descendants. Similarly, having a navel would have been fitting since it would have gestured at the fact that it is part of human beings to have a past, a past that included having a mother.
Likewise, if God created the world from scratch, then it would have been fitting for God to have given the world a past, because things that have no past are less perfect than things that have a past.
Of course, it would have been even more fitting, perhaps, for a thing to have a past, rather than the semblance of a past.
Under either hypothesis, evolution is fitting because it provides the natural past, a history, which makes a thing more perfect than something that lacks a history.
Blish, an atheist who seemed to know his St. Thomas, put the following into the mouth of his fictional Jesuit priest, who is confronted with an world that seems to confirm atheism, after explaing why the great artists were right to show Adam with a navel:
"What does that prove?" Cleaver said.
"That the geological record, and recapitulation too, do not necessarily prove the descent of man. Given my initial axiom, which is that God created everything from scratch, it's perfectly logical that he should have given Adam a navel, Earth a geological record, and the embryo the process of recapitulation. None these need indicate a real past; all might be there becasue the creations involved would have been imperfect otherwise."

Update: On the other hand, it seems that there are some who know that Adam and Eve did not have navels.
This article by Al Maxey at Grace Centered Magazine does a good job of rehearsing the navel/no navel debate, and even starts with my "angels dancing on the head of a pin" gibe, but concludes:
It is my firm conviction that to suggest God created Adam and Eve with navels is to suggest He is the creator of a grand deception, and I simply am unwilling to make such an assertion about my God. The Scriptures inform us that the created universe declares the glory and majesty of our God; it is a powerful witness to who and what He is. But, if the testimony of most every aspect of our universe is a LIE, then what does that say about the One who created it?! An atheist in England wrote the following to a Christian who was advocating the "Appearance of History/Age" theory, "Would you really have us believe in an alleged divine being that behaves that way?!" This person has a very good point. Do we really want to proclaim such a God to unbelievers?! If He has intentionally deceived us in some areas, then why not in others?!
It is my conviction He has not deceived us at all. Did Adam and Eve have a navel? NO, they did not! I can say this confidently not because I have special knowledge of the nature of Adam and Eve, but because I have special knowledge of the One who created Adam and Eve. The inspired Scriptures have revealed our Creator to us, and He is not a God who sets out to create a deception, an illusion, an appearance which is completely contrary to the truth. One could never trust such a God.
One must be impressed by Mr. Markey's ability to discern the status of our first parents' navels.
I don't necessarily disagree with his concerns, although I think that a world with a history is more perfect world than one without, which is one reason why I think that evolution isn't a "set up."
It seems like a lot may be riding on this bit of seemingly silly theological speculation.
Second Update: There may be a theological problem with Mr. Markey's analysis. Specifically, if there is evidence of evolution, and it is fake evidence, and God didn't fake it, then who did?
The answer to that question would gesture at some power other than God with the ability to create. That insinuation is the core of Manicheanism, which posited two creative powers, one which literally created the natural world.
In fact, that insight is the conflict that drives Blish's book.
