Here is the argument: if the sun was setting, its size would remain constant. If the sun was moving away on a flat Earth, then it would be getting smaller. What do you see in this video?
YT comment: sun gets smaller as it MOVES away from us because earth is stationary and flat, if sun simply rose and set it would stay the same size, tards will just say atmosphere to explain it away. link to proof of all that is said above: http://lunaticoutpost.com/thread-645999.html – Daersoulkeeper
