Beyond Space.
"And God said, Let there be a firmament in the midst of the waters, and let it divide the waters from the waters. 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." Genesis 1:6-7
The firmament is space:
" And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so. And 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. And God set them in the firmament of the heaven to give light upon the earth..." Genesis 1:14-17
These scriptures also shhow that space divided the waters from above from the waters from below. Ergo, the Bible has an explanation as to where enough water came from in order to flood the earth. The windows of heaven were opened.
