If you are Christian, you have to believe in magic, as the Bible is filled with it.
If you believe in New Age therapies, you probably believe in magic as well, as they routinely invoke untested or untestable magical ideas.

But where do you draw the line?

If you must believe in angels & demons, giants, wizards, talking donkeys & snakes (all mentioned in the Bible), do you also believe in unicorns, mermaids, leprechauns, gnomes, trolls, fairies, vampires, ghosts, elves, dragons, and werewolves?

If you believe in exorcisms (as clearly depicted in the Bible), do you also believe in voodoo power, magic potions, magical charms and talismans, rain dance, psychics, astrologers, and curses?

Would you believe in a creature I made up 5 minutes ago called the Hexegan Beast? What if I write a book about it and add some Photoshopped pictures of it as proof? What if 50 people told you they also heard about it. What if someone creates a TV show about it on the History Channel? Does it makes that beast more real?

What if I tell you I heard from my psychic that you can cure cancer using purple crystals blessed by a blind albino Shaman? Will you stop your medical treatment to follow it?

What if I tell you the angel Gabriel told me to leave my family, change my name to O’rok and go to a cave for 20 years? Will you think I’m crazy? If you’re Christian , Jewish or Muslim, you must believe in angels as it’s part of your Scripture — so why would you not believe me?

If you believe in magic, how to you tell if something is possible or not?
How do you evaluate a source of information?
How do you access if something is unreal or a hoax?
Do evidence count for something in that world view?
