Santa Claus is an old man with a beard that uses magical reindeer to deliver presents to every child on Christmas Eve.

Definitely a lie. Saying he's not is another lie, even if you're lying to yourself.

Are all myths, parables and stories lies? Is every metaphor a lie? (All the world is not a stage! It's a terrestrial planet!).

If the category "Lies" is identical to the category "Not Literally True", then it seems to be fairly useless.
