We know from the flood account that God opened the “windows of Heaven” in order to flood the whole earth with water and destroy the wicked. It is interesting that windows today are made of glass, and you can only open something that is closed and solid. God did not use all the water above though, because it says in Genesis 8:2 that the “the fountains also of the deep and the windows of heaven were stopped, and the rain from heaven was restrained.” God shut that windows and stopped the flow of water from above when there was finally enough water to cover the tallest mountain and the tallest tree. That means there is still water above the earth.
Mr. Lockyer, in describing his picture of the supposed proof of the Earth's rotundity by means of ships rounding a "hill of water," uses these words: - "Diagram showing how, when we suppose the earth is round, we explain how it is that ships at sea appear as they do." This is utterly unworthy of the name of Science! A science that begins by supposing, and ends by explaining the supposition, is, from beginning to end, a mere farce. The men who can do nothing better than amuse themselves in this way must be denounced as dreamers only, and their leading dogma a delusion. This is a proof that Earth, not a globe.
Rowbotham was a victim of a superior mirage. When flat-earthers hear this, they normally respond by dismissing this as impossible, because mirages supposedly are inverted images, but Rowbotham saw the boat right side up the entire time. However, this confuses superior and inferior mirages. What is the difference? First we must discuss the physics of light a bit.
25.) The surveyor's plans in relation to the laying of the first Atlantic Telegraph cable, show that in 1665 miles – from Valentia, Ireland, to St . John's, Newfoundland – the surface of the Atlantic Ocean is a LEVEL surface – not the astronomers' "level," either! The authoritative drawings, published at the time, are a standing evidence of the fact, and form a practical proof that Earth is not a globe.
