Tooth Fairy Bullshit

[Angrboda]

"I don't know" IS an answer.  Theists often seem to have the belief that admitting you don't know something is some kind of weakness.  On the contrary, the weakness is pretending that you know something you don't.  It's a sign of a weak mind.

Except you guys never lead with "I don't know".

Calling something a fairy tale implies you DO know...

Not knowing means you can't say one way or the other.

This is bullshit. Not knowing doesn't preclude one from ruling out specific answers. And in the case of naturalists answering the question, it's often implied that what they don't know is a plausible naturalistic explanation. Supernatural explanations are unbounded. Unless you've got something better than magic as an explanation, you've got nothing. The number of potential magical beings that could be responsible is infinite, and you have no way of narrowing that pool to one.
