Random thoughts? Random? You know what's random? Everything. It was random chance that caused life to evolve on Earth, random chance that killed off the dinosaurs to make way for mammals, random chance that a group of near-apes decided walking was easiest, random chance that the homo erectus beat out all the other hominids, and random chance that allowed humans to survive for such a comparatively lengthy time.
Congratulations, you are now aware of bleak and meaningless your existence is, and knowing that the universe is a cold uncaring non-entity which will be unaffected by your passing. All you can do now is make most of the tiny atom-sized blink of time you have remaining to you, and try your best to make yourself feel meaningful.
