Mythical being

For more information, see the Wikipedia article:

Legendary creature

A mythical creature is a fictional living thing, usually an animal or animal-like organism, that exists only in mythology or folklore.

Examples of (mostly) non-religious, mythical creatures include:

• Leprechauns
• Unicorns
• Dragons
• Loch Ness monster
• Bigfoot
• Fairies

Because most theists agree that non-religious mythical creatures do not really exist, they often serve as good substitutes for God in counter-apologetics, either to show the weakness of a theist's argument, or to show the reasonableness of a corresponding counter-argument.

Example

• Atheist: "Do you believe in leprechauns?"
• Theist: "No."
• Atheist: "Why not?"
• Theist: "Because they don't exist."
• Atheist: "Prove it."
