No, I don't believe a word of it.
Do you believe the Qu'ran is fact or fiction? How about the Egyptian Book of the Dead? Or the Popul Vuh of the Maya?
Or any other of numerous 'religious' texts from around the world? They can't ALL be right, but they can easily ALL be wrong.
Critical exegesis reveals the Bible to be a pastiche of creation myths borrowed from the surrounding cultures (Egypt, Babylon).
Note the similarities between the flood myths of the Bible and the Babylonian Epic of Gilgamesh.
You may say that the other texts I mentioned are made-up nonsense and surely fiction. Those who wrote them and believe in them will say the same thing about the Bible.
