Humans were like that. They knew of their own fragility, that life could be snuffed out in an instant, that a single rock from space could streak in from the heavens and wipe away everything they knew in a single flash of light and heat, and yet they spent their whole lives telling themselves that it was never going to happen. That they would die of old age in their sleep. They lived at all times inches from death, lying to themselves, ever planning for a future that might not come, never preparing for the fate that might.
