Oh, right, "Gap theory." Yes, that's considered a major viewpoint by many well-educated scholars; I missed your meaning at first, my apologies.
FTR, I simply espouse a more conservative stance -- given that the phrase in question is ancient, and we have relatively few contemporary uses of the word, we aren't positive of it's meaning. The only thing common among all of the possibilities is the chaotic, disorderly, "annihilated" nature of the thing. I cannot say with certainty what existed
before the "formless and void" status -- only that at that point, it was "formless and void" -- so I avoid interpretations that imply the details of what happened earlier. (shrug) Otherwise (and I hate to admit to this), I'm totally in agreement with you.

PS -- CS Lewis is good. Lee Stroeble also has an excellent book, a little more modern. Like Supe says, if you're comfortable with the status quo of your life, happy with everything deep down inside, and don't have any desire for a life-change, these are bad books for you to spend $5 on.
