Extraterrestrial diplomacy refers to the theoretical practice of establishing communication and relationships with intelligent life forms beyond Earth. This concept explores how humans might engage with alien civilizations, focusing on peaceful interactions, mutual understanding, and the potential for cooperation in areas like science and technology.
