I can prove it. Let me explain.
I quote from Isaiah 40:22 (a passage from a book of the Bible…well I must not assume everyone has heard of the Bible!).
Isaiah 40:22 (New International Version)
22 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.
The key phrase here is ‘circle of the earth’ and the key words following are ‘heavens’ and ‘tent’.
There can be no doubt from this that the writer – who must have been divinely inspired (what else?!) understood the worl to be FLAT. Why? Because he thought the world was DOME-shaped! ‘Circle’ is not the same as round. A dome is circular but it is flat.
The clincher: YOU DON’T PITCH A TENT (‘the heavens like a canopy’) AROUND A CIRCLE. YOU PITCH A TENT ON A FLAT SURFACE!
In London, out Millennium Dome is the shape of the biblical world. In America, your Louisiana Superdome is the same shape.
Come on you religios. Squirm out of that if you can.
