Genesis 1:6-8

Gen, 1: 6. And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
firmament=Heaven (Air,Space?) see. vs.8 And God called the firmament Heaven.

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.
And God made the firmament (it this a new one?)

8. And God called the firmament Heaven, And the evening and the morning were the second day.

Sum it up... God splits earth (void, water) into 2 pieces one on top and the other below and in the middle was Heaven (firmament) Hmmm...
