The alien language, known as MAKE UP A NAME , was eerily similar to the rare human language, Silbo Gomero, ADVERB whistled by the ADJECTIVE inhabitants of PLACE . Both languages used a ADJECTIVE complex system of VERB to communicate, likely evolved due to the need to communicate over long distances in mountainous or hilly terrain.
One theory is that both share a ADJECTIVE common PLURAL NOUN , dating back to TIME when humans and aliens coexisted on PLACE .
