I find it funny that flat earthers are not paying attention to the fact that there are hundreds, if not thousands, of pictures of a globular Earth, but not one photograph of this supposed ice wall.

That which lies beyond the ice wall has been written about in the past. In his book Exploratory journalist George RR Martin clearly explains that beyond the wall of ice is a terribly dangerous land of storms, mammoths, giants, reanimated corpses, and Wight Walkers. The wall is actually 1000 ft high, and NASA has commissioned a special military force called the Night's Watch to protect us. So there you have it roundies.
