Here's why:
* Omniscient narrators know everything about the story, including the thoughts and feelings of all the characters. This allows them to provide a comprehensive and insightful view of the events.
* This type of narrator is often used in classic literature and fantasy genres, where a grand and expansive scope is desired.
While an omniscient narrator is common, there are other types of narrators as well, such as:
* First-person narrators: The story is told from the perspective of a character within the story, limited to their knowledge and experiences.
* Third-person limited narrators: The story is told from the perspective of an outside observer, but they only have access to the thoughts and feelings of one character.
* Unreliable narrators: The narrator is biased or untrustworthy, intentionally or unintentionally misleading the reader.
The choice of narrator depends on the author's goals for the story and the effect they want to create.
