If there had been no rainfall (as we know it) up till then, with mists watering the ground like it says about the garden of Eden, they would have been astonished. Then when the springs of water from under the ground burst up in monumental fountains they would have been terrified. Considering that the first rainbow seemed to appear after the flood, that also lends itself to the view that no torrents of rain from the clouds had happened before the flood.
