Conclusions
nSome positives:
uThe word ‘heaven’ has 3 meanings – (1) the invisible abode of God, (2) the starry heavens, (3) where the birds fly.
uThe third of these is the firmament, the atmosphere.
uThe water ‘above’ the firmament is actually floating ‘upon’ the atmosphere.
uThis water takes the form of cloud droplets and perhaps water vapor also.
