If we just accepted Newton's work as finished and left 'god' insserted into the blanks in his work, we wouldn't have come very far since his time, would we? We can't fill gaps with 'gawd dun it' and call it good. We even can't put god in there at all! If he was needed, it would be obvious. The universe from the Big Bang til now has needed zero interference.
The reason someone brought the FSM is to prove this very point. Try inserting the FSM where you would put god into an area that lacks understanding. Did the FSM direct the formation of the universe with his noodly appendage? Why not? Because there is no reason to believe so, and no way to prove it. Same deal with any creator. God may still be real to you, but there is a reason almost all scientists don't believe in god or any creator. There is simply no need, it gets in the way of science and research.
It would do you well to read up on logical fallacies... It's tough at first, the WT has indee us to the tricks they use in every issue of the WT and Awake. It won't feel like it, but soon you will automatically be able to spot a fallacy... They jump out of a conversation and poke you in the nose. Just give it some practice! TBH the 'reasoning book' is good for this.
