Ok, so the FSM and Star Wars... haha. I did not know that is what they were. Very funny. I think Star Wars is a film, so it is hard to see that it can be taken seriously. (I can't believe I'm debating this) and to my knowledge, spagetti cannot fly. Now, in all serousness, perhaps there is another realm and another world where they can. Perhaps all things there are made of spagetti. But in this one, no.
The fundamental idea of God is to say that something exists that is primordial and archetypal before all other things, and that this 'thing' is or has sufficient energy to make everything we see around us. That is a very basic idea. Whereas something coming out of a tin does nothing accept sit on a plate. I know you see the difference. But you are saying that I can't diprove the one as you can't disprove God. But there is more to it than that. I hope you can see that. It is not a stretch of the imagination to think that there could be something that brings into being everything, and yet we cannot see it. That is the essence of the big bang is it not? That is not from spaghetti.
You must also consider that without intelligence (God) then you are ultimately relying on luck. And that just does not work, as much as people like to think it will. Nothing complex appears by luck in this universe. If you throw a pile of bricks out of a plane, you would not expect to see a house when it landed on earth. It never would. To form that, there has to be some guiding principle or process.
