I only within the past two years came to believe in Flat Earth. FE also comes with the package that: the sun is local, not millions of miles away; the planets are not physical so much as balls of light; the moon doesn't reflect the sun but gives off its own light; etc. There are a few of these add-ons that I believe as well, but not all. Perhaps I'm retarded.
The questions that remain are less than the questions that are answered. Perhaps it relates to the arc it travels across the dome. All I know is that, as the meme states, NASA lies.
