Why are aliens often portrayed as being humanoid?

Aliens are often portrayed as humanoid due to a combination of relatability and storytelling convenience. Human-like features make it easier for audiences to connect with these characters emotionally, facilitating the exploration of complex themes such as identity and morality. Additionally, the humanoid form simplifies the design and animation processes in film and literature, allowing creators to focus on character development rather than intricate alien Biology. This portrayal reflects our own biases and perceptions of life, often leading to a more accessible narrative.
