The origin of the gaseous heavens
The origin of the gaseous heavens is from the Earth: when the Earth was a flaming sun; and the emerging gases were in the form of smoke that was a mixture of seven gases [in addition to the constituents of the air like the Oxygen, the Nitrogen and CO2.]
And because some gases are heavy, while some others are light; they started to separate from each other; because the heavy gas came down while the light gas went up, till they became seven layers:
the first layer is the ozone gas [layer] about 25 miles away from us, the other layers came under it like the layers of the sulphur dioxide (SO2), the hydrogen, the helium and the rest of the gases. This is roughly speaking, for we cannot know those gases exactly because we are on the Earth and the gases are high up in the sky.
The indication, that the sky is gaseous, can be seen in the following Quranic revelation 41:11-12
ثُمَّ اسْتَوَى إِلَى السَّمَاء وَهِيَ دُخَانٌ فَقَالَ لَهَا وَلِلْأَرْضِ اِئْتِيَا طَوْعًا أَوْ كَرْهًا قَالَتَا أَتَيْنَا طَائِعِينَ . فَقَضَاهُنَّ سَبْعَ سَمَاوَاتٍ فِي يَوْمَيْنِ
The explanation:
(Then He tended to [build*] the sky and it had been smoke; He said to it and to the earth, “Come, both of you, willingly or loath.” The two said, “We [all] have come obedient.” And He separated them into seven firmaments in two days.)

[*i.e. to make the layers of the gaseous sky distinctive and to build them, or to arrange them as successive layers.]
The interpretation:
- (Then He tended to [build] the sky) means: the sky of the Earth,
- (And it had been smoke) means the smoke that emerged from the Earth which was in fact a mixture of seven gases,
- (He said to it) i.e. the sky [or the gaseous heaven]
- (and to the earth, “Come, both of you,) to the gravity
- (willingly or loath.” The two said, “We [all] have come obedient” And He separated them) and made them
- (seven firmaments); the explanation: He separated that smoke, and made it seven layers
- (in two days), i.e. within a period of two thousand years; that is because one day of the afterlife equals one thousand of our years.
