The latest WT issue deals with the question: "Why God Saved Noah --- Why We Should Care". Belief in the scientific accuracy of the Genesis account is supposed to be of paramount importance. Consider the following quotes:
Noah and the Flood - Fact, Not Fiction (p.3)
If the Deluge had not happened, then Jesus' statement about the days of the Son of man" would be meaningless.
Our Readers Ask --- Was the Flood of Noah's Day Really Global? (p.5)
How could Paul teach followers of Jesus the doctrine of truth if God's word contains myths?
Not only did Jesus believe that the Flood took place, but he also believed that it was global. In his great prophecy about his presence and the end of this system of things, he likened those events to the time of Noah.
If Noah was a mythical figure and the global Flood a fable, the warnings of Peter and Jesus for those living in the last days would be meaningless.
Are fact and fiction --- religious myth and scientific truth --- really diametrically opposed as the WT wants us to believe? As early as the third century the literalness of Genesis had been rejected in Christian thought by Origen. In a work titled "Did the Greeks believe in their myths?", Paul Veyne gives evidence that ancient people probably didn't believe in their Gods as we do. Maybe it's due to our scientific mind that we want our sacred writing to be scientifically accurate and infallible. Harvard theologian W.C. Smith, for instance, argues that (individual) faith and belief in its modern sense originated in the Renaissance period, thereby replacing (collective) religious experience.
