Have you ever considered that terms like the "expanse" and "the deeps" and "the waters" could refer to space? Because I think that if you take a lot of the Bible as metaphor, and not literal, it actually agrees a lot more with modern science. The Bible has "the Spirit of God moved upon the face of the Deep" and Science has the quantum void and the laws of physics. Science has the energetic explosion of the Big Bang, the Bible has "Let there be light!"
Plus, if the Earth and this dome are sitting on the water and on pillars, what are the pillars sitting on? And hoe large is this ocean that we exist in?
And lastly, the Bible also says, in *many* places in the Old Testament, that "the Sun rises and the Sun sets".
"The sun rises and the sun sets, and hurries back around to where it rises." - Ecclesiastes 1:5
"From the rising of the sun to the place where it sets, the name of the LORD is to be praised." - Psalm 113:3
"so that from the rising of the sun to the place of its setting people may know there is none besides me. I am the LORD, and there is no other." - Isaiah 45:6
