One of the hilariously ignorant things about fundies that pretend the Bible isn't geocentric is the studiously blind eye they turn to the reality that we know what the people who lived in that place and time thought about the subject. There seems to be a misperception (or a cultured ignorance) that the books of the Old Testament are the only writings extant from the era. They are not. They thought the earth was flat, and under a dome. Precisely as described in the Bible.
