Evidence

[Mothonis]

Two old fish are talking about the temperature of the water. A young fish asks "what's water?"

Oh, wait, I know this one!

And then one of the old fish turns to the young fish and says "open your eyes!" and the young fish swims away, disappointed with the low information content of the answer, his question unfulfilled. He's also thoroughly convinced that the old fish is senile, or possibly just full of shit when it comes to the existence of water.

Oh wait, no! I've got a better one!

The old fish says to the young fish, "water is everywhere, just open your eyes." Of course, in doing so, the old fish is missing out on the fact that this is demonstrably untrue, that water is not, in fact, everywhere, because there's also land, where water isn't present. Thinking about it, in the grand total of space in the universe, water is uncommon in the extreme. The old fish, it seems, is unable to distinguish between his blinkered and limited view of the world, and the totality of the real world. The young fish proceeds to prove him wrong by merely swimming to the surface and leaping momentarily into the air.

The old fish disagrees, and in order to prove himself right, swims deeper into the dark depths of the water. As he disappears from sight, the young fish hears a fading "see? There's still water down here! Water must be everywhere!"
