Where in the bible did you see that?
Well I did give the scriptures. I'll write out what it says...
Genesis 1:6-8:
6And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters.
7And 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.
8And God called the firmament Heaven. And the evening and the morning were the second day.
So we have the water on Earth, heaven (or 'sky' in other versions), then the water canopy. Water, heaven, water. Following so far?
Then in Genesis 1:16,17 it says:
16And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.
17And God set them in the firmament of the heaven to give light upon the earth,
This means that the stars, sun and moon are between the Earth and the water canopy. It's there plain as day- God set them in the firmament of the heaven. You know, that firmament between the two waters.
Now, stars are billions of light years away, they are not in our atmosphere (I hope you can agree with me on that point). This means that the water canopy had to be outside our universe.
