. The firmament is the expanse or the atmosphere.
That's not what the Lord says. Please explain how you explain that the waters above the heavens are also above the firmament created by God.
Psalms 148:1-6
1 Praise ye that the Lord from the heavens: praise ye him in the high places.
2 Praise ye him, all his angels: praise ye him, all his hosts.
3 Praise ye him, O sun and moon: praise him, all ye stars and light.
4 Praise him, ye heavens of heavens: and let all the waters that are above the heavens 5 Praise the name of the Lord. For he spoke, and they were made: he commanded, and they were created.
6 He hath established them for ever, and for ages of ages: he hath made a decree, and it shall not pass away
