Why are historians not sure if the Trojan war really happened?

Historians are uncertain about the historical accuracy of the Trojan War due to the lack of contemporary written records and the blending of myth and history in ancient texts like Homer's "Iliad." Archaeological evidence suggests that a city matching Troy's description existed and faced destruction, but it's unclear if this aligns with the legendary war. Additionally, the war's portrayal may have been influenced by oral traditions and embellishments over time, complicating efforts to distinguish fact from fiction. This uncertainty leaves the event straddling the line between myth and potential historical occurrence.
