Why is comet is a sign a bad omen?

Comets have often been viewed as bad omens throughout history due to their unpredictable appearance and association with significant events, such as natural disasters or the deaths of rulers. Their bright and unusual presence in the night sky can evoke fear and anxiety, leading people to interpret them as harbingers of misfortune. Additionally, ancient cultures often lacked scientific explanations for comets, attributing them to divine displeasure or impending calamity. This superstitious interpretation has persisted in various forms across cultures.
