2. Another related thing I don’t understand: if the sun and moon are always above the disk of the Earth, why can’t everyone in the world see them at all times? Surely they should always be visible, at least at a low angle. I can’t draw myself any diagram where they are not always visible, but we see that that doesn’t happen. I can’t see how night time happens. Help! 

The Flat Earth, God’s true creation, is a beautiful, peaceful Truth, making you very valuable and the center of God’s Creation. The first chapter of Genesis clearly describes a flat, Stationary earth, set on pillars on the deep waters, with a glass dome (Firmament) above, and with the sun and moon inside the dome. The Ball Earth is a Satanic lie. It doesn’t exist, except on screens, in textbooks, and in people’s programmed minds.
Astronomers, in their consideration of the supposed "curvature" of the Earth, have carefully avoided the taking of that view of the question which - if anything were needed to do so -would show its utter absurdity. It is this: - if, instead of taking our ideal point of departure to be at Valentia, we consider ourselves at St. John's, the 1665 miles of water between us and Valentia would just as well "curvate" downwards as it did in the other case! Now, since the direction in which the Earth is said to "curvate" is interchangeable - depending, indeed, upon the position occupied by a man upon its surface - the thing is utterly absurd; and it follows that the theory is an outrage , and that the Earth does not "curvate" at all: - an evident proof that the Earth is not a globe.

156) People also claim to see curvature in Go Pro or other high altitude camera footage of the horizon. While it is true that the horizon often appears convex in such footage, it just as often appears concave or flat depending on the tilt/movement of the camera. The effect is simply a distortion due to wide-angle lenses. In lens-corrected and footage taken without wide-angle technology, all amateur high-altitude horizon shots appear perfectly flat.
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.
