Why did montezuma not attack the invading spainiards?

Montezuma II, the Aztec emperor, did not attack the invading Spaniards led by Hernán Cortés for several reasons. He initially believed Cortés might be a deity, Quetzalcoatl, returning as prophesied, which caused hesitation in direct confrontation. Additionally, Montezuma aimed to avoid conflict to maintain stability and protect his empire, as he was uncertain about the Spaniards' true intentions and military capabilities. This indecision ultimately contributed to the downfall of the Aztec Empire.
