I have read that Job would be the oldest book in the Bible; I've also read that the character of the Satan in it would come from Babylonian influence, which would contradict the first point, since books like Isaiah (the first half of it I believe?) are, as far as I'm aware, accepted as having been written before the exile.

Is there a concensus on when the book of Job was written? And on what the oldest book of the Biblr would be if not this one?
