This is ironic. They didn’t say they believe. You offered your belief that you know something that happened long ago (extraordinary claim), and they are naturally curious how you could know that. If you’re a time traveler or whatever we’d be quite interested to hear more.

You're the one who believes magic is real, it's up to you to explain it. Extraordinary claims and such.

Not everyone whose unfalsifiable beliefs differ from yours lacks maturity. In fact, some of them are mature enough to not resort to insults.
