The Flood and the Coming of the Son of Man

Jesus compares the coming of the son of man to the days of noah because it's a familiar literary comparison that people will know about. If he's not trying to teach us about noah, that means we can't press the details of the passage to show that noah was a historical individual. The text also has the flexibility to allow jesus to refer to noah even if JESUS knew that the text was figurative. So i don't think that jesus's reference to noah settles the matter one way or the other.
