let me start off with one of the biggest supporters of flat Earth... The United Nations
they use the flat Earth model on their logo.
my entire life i've been living thinking the Earth is flat, because that's what i was taught in school. but of course when you live in a world where you are taught as a child that the Earth is a sphere, and then when you are growing up and you see the indoctrination that large international corporations and companies use as their logos (https://goodlogo.com/tags/globe) so you end up seeing at least one globe a day, anything different seems outlandish. after i did some actual research on the topic and saw both sides of the story, it made a lot more sense to me. of course you guys will try to disprove me with your logic that was engrained in you as a child, but i'm gonna try to answer any of your questions, no matter how ridiculously outlandish and spherical they may sound.
i often get asked dense questions like "how did Pearl Harbor happen if the Earth is flat? Did the Japanese really swim through the Indian Ocean, the Atlantic Ocean, and the Pacific Ocean to attack Hawaii?" because they think that flat earth believers assume the flat Earth is basically a copy of a spherical Earth map but flat. no. this is what the map of the Earth looks like:
another thing that people manipulated by the world government love to ask is how the day/night cycle works on a flat Earth, heres a diagram:
Sun rays: The sun is a lot smaller than has been ingrained in your minds since childhood by government-controlled schools and people that just don't know better. and it's a lot closer to Earth. how would you get sunrays like this otherwise?
The horizon always appears perfectly flat in every direction around you regardless of how high up you are. All amateur balloon, rocket, plane and drone footage show a completely flat horizon over 20+ miles high. Only NASA and other government “space agencies” show curvature in their fake CGI photos/videos. and no matter how high up you go, the horizon is level. you don't have to look down, which would be the case with a spherical Earth
Engineering: Surveyors, engineers and architects are never required to factor the supposed curvature of the Earth into their projects. Canals, railways, bridges and tunnels for example are always cut and laid horizontally, often over hundreds of miles without any allowance for curvature.
Stars: “Olber’s Paradox” states that if there were billions of stars which are suns the night sky would be filled completely with light
Distance the further South you go: If the Earth were truly a globe, then every line of latitude south of the equator would have to measure a gradually smaller and smaller circumference the farther South travelled. If, however, the Earth is an extended plane, then every line of latitude south of the equator should measure a gradually larger and larger circumference the farther South travelled. The fact that many captains navigating south of the equator assuming the globular theory have found themselves drastically out of reckoning, moreso the farther South travelled, testifies to the fact that the Earth is not a ball.
Antarctica: In the ball-Earth model Antarctica is an ice continent which covers the bottom of the ball from 78 degrees South latitude to 90 and is therefore not more than 12,000 miles in circumference. Many early explorers including Captian Cook and James Clark Ross, however, in attempting Antarctic circumnavigation took 3 to 4 years and clocked 50-60,000 miles around. The British ship Challenger also made an indirect but complete circumnavigation of Antarctica traversing 69,000 miles. This is entirely inconsistent with the ball model.
Gravity: A spinning wet tennis ball, for instance, has the exact opposite effect of the supposed ball-Earth! Any water poured over it simply falls off the sides, and giving it a spin results in water flying off 360 degrees like a dog shaking after a bath. Astronomers concede the wet tennis ball example displays the opposite effect of their supposed ball-Earth, but claim that at some unknown mass, the magic adhesive properties of gravity suddenly kick in allowing the spinning wet tennis ball-Earth to keep every drop of “gravitized” water stuck to the surface.
