FSM was invented because a few years ago some ID proponents wanted religion in schools, but explicitly saying God in the books had been repeatedly knocked down as unconstitutional. As a way around that they pushed ID in a more pure form, the point being for people to infer that God was the one responsible for the ID (of course). So this kid invented the FSM and said that if they can believe that God was the one who did the ID work well he could also have his belief that it was the FSM that was responsible for intelligent design. It was inspired satire.
Intelligent design is one of the more retarded ideas still around, even multiple popes and the Vatican call it silly.
That said, please oh god of pasta, bless thy bolognese sauce so that it is thick and rich yet does not burn the tongue. Anoodle.
