The Bible doesn't
teach anything about the shape of the earth. The people who made mention of the shape of the earth just wrote what they matter of factly believed...
22It is he that sitteth upon the circle of the earth, and the inhabitants thereof
are as grasshoppers; that stretcheth out the heavens as a curtain, and spreadeth them out as a tent to dwell in:
You do understand the difference between a circle and a sphere, don't you? You do know that a circle is essentially a flat 2-dimensional (FLAT) construct, don't you?
