The Bible states that the earth is a disc or circle, which is flat; it is supported by pillars and surrounded by waters on all sides, underneath and above. There is a dome- or vault-like firmament that prevents all of the upper waters from drowning everyone, but it allows rainwater and snow through. The Sun, Moon, and stars move in fixed tracks along the underside of this bowl.
