The Flying Spaghetti Monster (FSM) is the deity of the Church of the Flying Spaghetti Monster or Pastafarianism, a social movement that promotes a light-hearted view of religion and opposes the teaching of intelligent design and creationism in public schools. Although adherents describe Pastafarianism as a genuine religion, it is generally seen by the media as a parody religion.
The "Flying Spaghetti Monster" was first described in a satirical open letter written by Bobby Henderson in 2005 to protest the Kansas State Board of Education decision to permit teaching intelligent design as an alternative to evolution in public school science classes. In that letter, Henderson satirized creationism by professing his belief that whenever a scientist carbon-dates an object, a supernatural creator that closely resembles spaghetti and meatballs is there "changing the results with His Noodly Appendage". Henderson argued that his beliefs were just as valid as intelligent design, and called for equal time in science classrooms alongside intelligent design and evolution. After Henderson published the letter on his website, the Flying Spaghetti Monster rapidly became an Internet phenomenon and a symbol of opposition to the teaching of intelligent design in public schools.
