Atheism is irrational.

[Tonus]

I don't know about "made up." Growing up I heard all kinds of ghost stories from my mother. Some were so over-the-top I can only assume she was passing along old urban legends she'd been told. Others were more sublime. As a Jehovah's Witness, I can recall hearing of a few different 'miracles' but those were usually third/fourth-hand and sometimes sounded like more urban legends. But I can also recall another such event where people explained how one JW --upon partaking of the wine and bread at the annual observance of Christ's sacrifice*-- seemed to radiate with a visible glow. Several people claimed to have witnessed it. How to take such a story?

The skeptic will be... skeptical, of course. And without names and corroboration (the name of the person was given the time that I heard of it, but I do not recall it) there's only people's word for it. To a JW it is difficult to resist the temptation to note that it is a sign that they are indeed God's people, as they have a long list of such miracles that confirm for them that Jehovah is watching over them. To a non-JW? I suppose many theists who are not JWs may share the view of the skeptic or may consider it an example of Satan finding ways to deceive the faithful, or even a legit miracle that happened to someone in the wrong denomination. For me, that's where the problem is-- that a person who is certain that event A must be a miracle are likely to dismiss event B because it doesn't square with their worldview, even if those events are just as difficult to prove or disprove.

*- JWs only have one religious observance, and that is an annual mass where only "the anointed" are to eat of the bread and drink of the wine that symbolize Christ's flesh/blood.
