This 'Flying Spagetti Monster' used by atheists to try to build an argument against the existence of God is such a poor analogous example, that when it is mentioned, I can't help but giggle because of how amusing it is. This 'being' (which of course, nobody believes in, neither atheist nor theist) does not compare to what theists believe in, that is, it does not compare to a transcendent God Who has revealed Himself to humans throughout the history of mankind. The atheist, because they have not seen with their own eyes (which can only see a miniscule spectrum of energy wavelength), and because they cannot comprehend a being that would be outside the limits of time and space and their fallible three pound brain and the limited sensual perceptions associated with it, then quite arrogantly presumes that God must not exist. Oh the folly! Oh the vanity! That because their tiny brains cannot accept God Who is beyond them that He must not exist!
This 'being' called the Flying Spagetti Monster, which is used by atheists to mock those who believe in God, is a recent term, of which even those 'adherents' to this 'monster' do so jokingly with no serious faith in such a being's existence.
Where in history can they point to people believing in such a being made of linguini? The belief of God, on the other hand, goes as far back as human history, across all cultures around the entire globe.
Where in history can they point to prophecies which infer about a being made of pasta? Are there any? Whereas the prophecies of the Bible are numerous, coming true even today with revelations. In the Old Testament alone, the prochecies about Jesus Christ number over 250, including how He would be born, where He would be born, when He would be born -to the very year!-, how He would die, the miracles He would perform, etc, etc. Never, ever, in the history of mankind, have so many prophecies been so specifically fulfilled then with the Person of Jesus Christ.
Think on this, the probability that Jesus could have fulfilled even eight such prophecies (forget about the remaining 250) would be only 1 in 10^17. That's 1 in 100,000,000,000,000,000!
That would be enough silver dollars to cover the face of the entire state of Texas two feet deep. Now I've been never been to Texas, but I know it is a big state and can take many hours and even days to drive across. Who in their right mind would suppose that a blindfolded man, heading out of Dallas by foot in any direction, would be able, on his very first attempt, to pick up one specifically marked silver dollar out of 100, 000, 000, 000, 000, 000?
The reasons are many as to why using a make-believe and mockingly-derived Flying Spagetti Monster to compare with God is a false comparison, and I really could go on and on, but the greatest and most profound proof has to do with the testimony of man and that men and women have since the beginning of time given the greatest witness possible (that is, with their very lives) to witness to the belief in the existence of God. That God has revealed Himself, not only in the forms of a Burning Bush or a Dark Cloud or a Pillar of Fire or ultimately in the Person of Jesus Christ, that is, to the vision and hearing and touching of which men and women have experienced and recorded and suffered for and ultimately died for, but even greater and more profound, with the experience of God witihin the hearts of countless people throughout the entire history of mankind. For God reveals Himself to the humble and poor in spirit, not to the proud and vainglorious doubter. God reveals Himself to those pure in heart, not to those who excuse their sins and passions as a natural human attribute, as if that somehow excuses them for the evil they do.
Until the atheist, full of pride for his self-made god and idol (which is his three pound brain) humbles himself and repents, tand open the door of his heart and allow God to enter therein and reveal Himself, then he will continue to laughingly use the Flying Spagetti Monster as his crutch and his defense.
