The Flat Earth Society
From the FAQ:
Q: "Is this site for real?"
A: This site is real. There are people who seriously believe the Earth is flat. However, there are also people on this site who do not.
Q: "Why do you guys believe the Earth is flat?"
A: Well, it looks that way up close. Also, Samuel Rowbotham et al. performed a variety of experiments over a period of several years that show it must be flat. They are all explained in his book, which is linked at the top of this article.
Don't worry it gets better:
Q: "How did NASA create these images with the computer technology available at the time?"
A: Since NASA did not send rockets into space, they instead spent the money on developing advanced computers and imaging software instead
PLEASE NOTE This means that pictures confirming the roundness or flatness of the Earth DO NOT IN THEMSELVES CONSTITUTE VALID PROOF.
If 2000 year old dead bodies could spin in their graves, Eratosthenes's would be doing it about now.
