In their cognition, the earth is flat, just like an unfolded disk. The North Pole is in the center of the disk, surrounded by the ocean, and the continents are floating in the ocean. The edge of the disk is the South Pole, which is an ice wall composed of icebergs tens of meters high to prevent the water in the ocean from losing at will. Beyond the Antarctic ice wall, there is another parallel world, and he even thinks that the earth is a huge world. Aliens are watching us outside the fish tank. When our civilization developed to cross the Antarctic ice wall to reach another parallel world, these aliens made up conspiracy lies through the heads of human governments, and they arbitrarily announced their geographical theories in order to manage our human beings imprisoned on the earth more conveniently. Anyone with a little common sense knows that these words are full of loopholes and simply cannot stand scrutiny.
But at present, there are at least hundreds of thousands of people who believe in horizon theory, and they have also set up an organization for this purpose. In today's highly developed civilization, we have taken many photos of the earth, but these advocates of the horizon. However, I think no matter from which height we look at the earth, it will always be flat, without any radian, and it is not a sphere at all. Only official photos will show that the earth is round. At the same time, their other evidence is that there are routes flying over the North Pole in the world, but all countries prohibit planes from flying over the South Pole, because when they fly over the South Pole, they will enter another parallel world. So they think that all countries use fake photos of the earth to hide the truth from their people, because few people can go into space. What we see is what aliens want us to see. They firmly believe that they are right. Anyone who disagrees with their views is a poor person who is deceived by lies.
