Why do saiyans look like a human?

Saiyans, a fictional race from the "Dragon Ball" series, resemble humans primarily due to the creative choices of their creator, Akira Toriyama. This design choice allows for easier storytelling and character development, as it enables audiences to relate to them more readily. Additionally, it establishes a connection to Earth and its inhabitants, enhancing the narrative's appeal. The humanoid appearance also facilitates engaging fight scenes and interactions within the show's universe.
