"sin has degraded our genetic material"
"the book that God left us in order that we understand some fundamental things about Him."
Ah, so instead of evolution imroving the species, do you see it as slowly degrading the species?
And, presumably, early man was still near enough perfection to understand the fundamental things about God, but, when mankind had degraded enough, God saw the need to make man literate, and (over a period of a couple of thousand years) to write him a book.
It makes sense, of a sort,
