Agnostic: a pointless term?

[AFTT47]

I don't think the unicorn is a good analogy for God. If we're looking for a unicorn here on Earth, there are only so many places where it could possibly be. The chances of an animal that size existing on this planet without a single shred of evidence is essentially zero. The situation with God is different. It could be entirely outside the universe, in a region between multiple universes. There is no reason to believe there is such a critter but we're talking about a realm we know nothing about. Not only is it impossible to rule out but I don't see how anyone could begin to predict odds.
