Pretty sure it does talk about astronomy in Genesis, but even if the Bible said the world was flat, it isn't. The Bible also talks about plagues and "the angel of the Lord smote the Assyrians", 185,000 of Sennacherib's soldiers (2 Kings 19:35). Pretty sure these were some ancient epidemic, possibly a virus, like the ones mentioned by Hittite and Greek writers like Thucydides.
So one thing that Book was right about, there is nothing new under the sun.
