Some even believe that the designer has them in mind specifically. These are merely superstitions borne out of fear and ignorance. Nothing is eternal. Everything we value will eventually fade away into the obscurity of nonexistence. A million years from now, or so, the sun will explode leaving no traces of our frenzied efforts to make a mark on the universe.
Death is nothingness.
Even life doesn't offer that much. The world is a mechanism set in motion by random forces. Whatever happens is the result of those forces, and there is nothing we can do to change it. Human beings like to think that we have power to create events and shape the future. That's just more arrogant ignorance.
