In the “no rain” scenario the “waters above the firmament” would be a atmospheric canopy of air and evaporated (or whatever) water suspended up there as a dense cloud cover. Trillions and trillions of litres of the stuff possibly creating a sub tropical climate over most of the earth which was rich vegetation watered by condensation. Horrible humidity.
