I was amused to hear the announcer on ABC FM intro The Creation by Haydn, explaining that the problem for the librettist was that there was no story!
Unlike those who would have us believe that the creation account is (merely) a story, an arts person can see the blinding obvious: there's no story here folks, just facts; move along now.
Thus, of course, Haydn's librettist had to use his imagination to make a story out of the bare account he had to work from.
