Okay, the KJV says...
1 In the beginning God created the heaven and the earth.
...then the text seems to move on to describing what is happening on the earth. Hmmm, heaven is singular in the KJV...
Then...
6 And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
7 And God made the firmament, and divided the waters which
were under the firmament from the waters which
were above the firmament: and it was so.
8 And God called the firmament Heaven.
Ah! I see. I was reading the NIV...in the NIV verse 8 doesn't refer back to verse 1. The NIV has vault and sky and never goes back to saying heaven.
So the KJV would seem to indicate that the waters are all a part of earth and that the firmament in the midst of the waters is heaven which is also the atmosphere. So Heaven IS the firmament and the firmament is still what is between the waters. I'm still assuming that the clouds are of the "waters which were above". This is an infinite sandwich organization with waters as bread and heaven as the filling.
So the air we breathe would appear to be the atmosphere of heaven!
I don't think this is what you think but perhaps you would care to explain (again?)?
However, given the reference in 8 back to 1, then we have that verses 1-8 describe both the configuration of the earth and the appearance of heaven.
So in...
20 And God said, Let the waters bring forth abundantly the moving creature that hath life, and fowl
that may fly above the earth in the open firmament of heaven.
...we can see confirmation that heaven is where the birds fly and where we walk and breathe.
I honestly have never read this this way before but the more i do the more I like it. This is the most humble description of heaven and earth and it befits a sense of the Universe as not being more than is practically experienced. Really a most scientific perspective given the knowledge of the time and the propensity of most cultures to want to make much more of heaven than this.

Genesis 1 KJV
