There is no faith required to not believe in fantasy characters.
I agree. But the Christian claim is different from the “flying spaghetti monster” claim. The Christian claim as I understand it is that there was a man called Jesus from Nazareth who lived, was crucified (something the historical record attests to with Josephus), and then resurrected (something the gospels affirm, but which is of course open to doubt unless you were there).
And more generally, to deny theism requires faith, as the empirical evidence we have does not answer the question of how something came from nothing (the creation of the universe).
Stephen Hawking wrote that all was needed for the creation of the universe was gravity – but it still begs the child-like question, where did gravity come from?
For the record, I’m not sure of anything, but atheists who claim the universe could have created itself are making as outlandish an assertion as the early Christians who said that God became a man in the form of Jesus.
