Welcome to EvC, FS.
Well, I really can't add anything to what crashfrog has already posted, but my ego is far too big to pass this up.
It is true that so far we don't have a naturalistic explanation for human consciousness. However, not knowing the explanation is not the same as there not being an explanation at all. There have been many questions in science where we had to wait for the correct explanation. There are still many unanswered questions in science, but for many of these no one (not even creationists) doubt that we will eventually find the answer. I don't see why consciousness shouldn't be in this class.
Several examples come to mind. It was believed that the behavior of celestial objects were due to very different principles than the behavior of objects here on earth. But we now know that the same physical laws that explain phenomena here on earth also suffice to explain the phenomena we see in the sky.
Likewise, it was believed that life was due to very different principles than non-life. Again, we eventually learned that all the biochemical processes that add up to what we call "life" are just the result of ordinary matter acting according to the mundane laws of chemistry and physics.
In the same way, despite one's feeling that there must be something different about the human "soul", there is nothing to suggest that it cannot be explained in terms of neurobiology, even if we do not yet have an adequate theory.
In fact, there is plenty of reasons to think that it might just be the result of ordinary biology and chemistry. Injuries to the physical brain can result in severe changes in personality, as does the action of mundane chemical substances (so called narcotics). If this "consciousness" or "soul" has something to do with one's personality, with
who a person really is, then it seems to be very deeply connected to the physical brain and its chemical workings. One is left wondering, in this case, what is there left for an immaterial, ineffable "something" to do in the way of providing an explanation.
Actually, if their god makes better pancakes, I'm totally switching sides. --
