Is the Earth a Flat Disc?

Is the earth really a globe, or spherical, as science tells us, or is it perhaps a flat disc, which rests on pillars, as some teach who claim that they base their conclusions on the Bible? How are we to understand Scriptures which tell us that the sun stood still or that it runs its race? Doesn’t this show that the sun revolves or orbits around the earth, rather than the earth revolving around the sun? And doesn’t the Bible say that the earth does not move or rotate? But how can there by day and night at the same time, when from sunrise to sunset, the sun shines during the entire time on the “flat earth”? What happens to the waters of the oceans, if the earth is a disc?
