Was Noah a real person?

In the book's own words

But Noah really lived; he was a wine maker of Aram, a river settlement near Erech. He kept a written record of the days of the river’s rise from year to year. He brought much ridicule upon himself by going up and down the river valley advocating that all houses be built of wood, boat fashion, and that the family animals be put on board each night as the flood season approached. He would go to the neighboring river settlements every year and warn them that in so many days the floods would come. Finally a year came in which the annual floods were greatly augmented by unusually heavy rainfall so that the sudden rise of the waters wiped out the entire village; only Noah and his immediate family were saved in their houseboat.
