I agree. Just because things sound impossible or we don't quite understand all of the Bible, does not mean it is not literal.
I say: "I believe God's words even though they seem improbable." He's God and he can do whatever he wants. He made the universe and all unknown laws of it. Even if he decides to alter or step outside those laws, he is still acting as God and we should know who we are in comparison when we suggest God's word is not 'accurate' or 'literal.'
Who are we? Do we have infinite knowledge? Can I say there is no____ in the entire known universe, for anything? Doubt it.
