The way I understood the spaghetti monster was as an illustration of the absurdity of pretending to know for sure anything that's in the realm of irrationality. Anthropomorphism of god (rain gods, god hates studmuffins or doesn't, prayer does or doesn't help, etc). Just because a ton of folklore has accumulated around the myths of god (old grandma BS sort of stuff) doesn't invalidate the philosophical notion of god.
What's ludicrous about something beyond the reach of your understanding? I don't picture god as an all powerful being that created everything and watches everything, or as anything else. I don't picture it at all. You could say I dismiss it out of hand, but not because I think it's true or false or unlikely or not, but because being beyond what I can understand and therefore predict, it's by principle a non-factor.
It's as elementary as 2+2=4 that if something is beyond your understanding, it's unpredictable in any way.
God isn't just beyond your understanding like 21st century tech is to cavemen, it's infinite.
So "god" is in fact as ludicrous to our scale of thinking as changing into a rocket etc. That it makes no sense is more proof of the ludicrous dissimilarity between us and it.
It does not take faith to believe it does not exist.
Belief is faith.
I'm not splitting semantic hairs or trying to get into a last-word argument here, the matter's really clear: God cannot be proven or disproven (where is your proof? No proof = no certainty), and yet (in your own words) you believe. You're positive god is inexistant, with ridicule or disbelief (I think the formal name is
argument from disbelief) as justification. Look it up, it's not a valid argument.
Would you take it seriously if someone answered your post with only "I don't believe that/it doesn't vibe with my instincts, so it just can't be true"?
