I guess the religion you follow conveniently ignored that for 1500+ years.<quoted text>
New International Version
He sits enthroned above the 'circle' of the earth, and its people are like grasshoppers. He stretches out the heavens like a canopy, and spreads them out like a tent to live in.
A circle is flat; think of a pancake.
Job 38:15 "The earth takes shape like clay under a seal." (Clay when stamped under a seal is flattened and round in shape).
