JUST OPEN YOUR HEART, DAMMIT!

Furthermore, you could claim anything exists as long as there isn't evidence to say that it doesn't.

You can't prove Santa doesn't exist! On December 24th I left cookies and milk by the tree, and when I woke up the next day the cookies and milk were gone and there was presents under the tree. You can't explain that. Thus, Santa is real!

Alternatively, we could send an expeditionary group to the North Pole to find Santa's Workshop. Failing to do so, we might conclude that this (and other similar shortcomings) renders the Santa story untenable.

But when you send someone to the North Pole to find Santa (assuming that that's even where Santa is "truely" located), Santa just moves. Maybe he's really in the sky. Nope not there. Maybe he's really on the moon. Nope not there. Maybe.... awe screw it, maybe Santa is really just outside space and time.
