In my experience talking to Christians I’ve learned to not assume I know the beliefs of the individual...with a few exceptions. Every Christian I know believes that Jesus Christ existed, that he was crucified, and that he rose from the dead. From there they vary wildly. A big disagreement is over which Biblical bits are historical and which are fictional stories--beliefs that are dependent on their personal credulity or that of their chosen church.
The resurrection of Christ is so indoctrinated into their culture that it’s unquestioned and taken for granted even when talking snakes and planetary floods are considered too outside the realm of possibility to be seen as factual. This cultural familiarity somehow makes ideas plausible. So lets imagine something unfamiliar.
“Woman gives birth to squid!” How’s that for a headline? Imagine you read that, not as a modern headline, but as an event expressed in a book over a thousand years old. The obvious context is that every woman you’ve ever known has given birth to a human boy or girl, every account from every person since you were born bares out the identical report, and every historical record of births since modern bookkeeping confirms that humans give birth to humans. So would you believe that a woman from antiquity bore an ink-squirting, tentacled baby? Given that, biologically speaking, there is no mechanism for such a birth to be possible, would a Christian believe it?
I doubt neither you nor that Christian would accept such a claim, because it’s absurd, sure, but more importantly it's novel. There is no cultural familiarity with the notion of squid-babies (outside of that one scene in Men in Black.) If everyone you knew happened believed that old squid's tale from childhood....suddenly it becomes plausible. Credulity becomes communal when fitting in is praised over critical thought. I think that's a given. How we change that requires more thought.
