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 the letter, Henderson demanded equal time in science classrooms for "Flying Spaghetti Monsterism", 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.
