This is what I believe: People who persist in believing in the "supernatural" do so only because they are ignorant about the universe. They do not see the wonder and incredible beauty of the cosmos, and because of their mundane view of the natural world they feel the need to invent and believe in a world beyond the natural world, a "super-natural" world separate and above the laws of nature, a world populated by ghosts and demons and gods and spirits and other fictional creatures, for the sole purpose of making the universe feel like a more exciting place. There are enough amazing things in the entire universe such that no one should feel the need to believe in things beyond it simply to make the universe more interesting or more beautiful. After all, by observing and studying the universe, scientists discover again and again that the universe is a place greater and stranger than the wildest products of our imagination. Why bother, then, to construct a "supernatural" element of the universe and believe it to be more than the fiction that it is?

People believe in the super-natural not because they want to, but because they've been convinced by whatever they've seen or experienced. To them, the "supernatural" IS part of the natural.

"Supernatural" is, by definition, not part of the natural world. Just look at the word: "super" means "above" or "beyond," therefore "supernatural" literally means "above nature." But I guess that's just semantics...
Anyway, with human memory and pattern recognition being as fallible as they are, how could anyone trust them over empirical observation and scientific study? It just doesn't make sense.
