Insignificance

Even though this amazing film provides some sense of scale, it's still impossible to get one's mind around what a tiny atom in a single grain of sand in an immeasurably huge desert we are.

It does, however, explain a little of why so many humans, rather than accepting the mystery and finding pleasure in it, feel the need to ascribe meaning and answers where there are none; and how self-indulgent and delusional most answers really are.
