In 2005, a guy named Bobby Henderson founded The Church of the Flying Spaghetti Monster to protest the Kansas State Board of Education's decision requiring schools to give Intelligent Design Theory representation along with Evolutionary Theory. Henderson wrote an open letter to the education board sarcastically asserting that the "Pastafarian" belief that a Flying Spaghetti Monster created the universe should also receive equal representation in the classroom.
Get it? Believing in God is like believing in a Flying Spaghetti Monster. Ah ha! It's superficially clever, so it must be true.
Since then, the Flying Spaghetti Monster has become a media sensation and an icon frequently used by Atheists/Agnostics to mock Theism. Apparently, what passes as an argument with Atheists these days is replacing the main character of a narrative with the words "Flying Spaghetti Monster" and laughing at how absurd the altered narrative sounds.
Can I try too? In 1860, a Flying Spaghetti Monster was elected President of the United States. A bloody war between the Southern and Northern States ensued. The Flying Spaghetti Monster eventually saw the restoration of the Union, emancipated America's slaves, and was shot in the back of the head at Ford's Theatre by John Wilkes Booth.
Wow. I had no idea it was so easy to disprove the existence of Abraham Lincoln.
