Here's his argument:
"There are APikorsim who ask, how do you knwo that G-d created the world? Maybe it was the SPaghetti Monster?
The answer is, it is possible that the spaghetti monster created the planet earth, or people, but since the spaghetti monster is, presumably, a physical entity, or at the very least, an entity with certian attributes which makes him the spaghetti monster, then it cannot be he First Cause, who created all reality. In other words - the spaghetti monstrer could not have created the world since he is part of the world. Simply put: If the spaghetti monster created the world, who created the spaghetti monster? There has ot be a First Cause at the end of the chain, with no attributes or limitaitons at all.
Call that First Cause whatever you want --- Jews refer to it as Hashem."
Let's leave aside the flaws in First Cause theory for a moment. If there's a first cause, why can't it be the FSM? Frumteens claims because the FSM has to be part of the world (because he has to have specific attributes to be a flying spaghetti monster) and therefore can't be the first cause.
But why must the first cause have no recognizable attributes? G-d clearly has some attributes because something with no attributes is nothing. For G-d to be the first cause whatever attributes he has must have existed prior to creation. So why is it impossible for spaghetti to exist before creation?
Why is the FSM anymore part of the world (or reality) than G-d?
