Things we all must believe in now because there is no absolute evidence that they don't exist:

All cryptozoological creatures, including Bigfoot, the Jersey Devil, and the Loch Ness monster

Fairies

Dragons

Compassionate Tories

Father Christmas

The Man in the Moon

Elves

Unicorns

Mermaids


Not only must we now believe in them (simply because we can't prove that they DON'T exist), we must also construct elaborate belief-systems around all of these creatures, in whom we now have an unshakeable faith, and expect them to use their powers to Save the Cheerleader and Save the World. How they are meant to do this i'm not certain, but some things Just Aren't Meant To Be Known. *Nods very wisely*

I'm just off to pray to Trixie, the gnome at the bottom of my garden.
