Question: Who made the first language? 

Answer: Language is not necessarily vocal; it could be sound or anything even animals have their different forms of language. According to the bible and evolution theories, animals were created or evolved before man, so the first animals, probably the ones that had a sense of relating amongst themselves( maybe colonial bacteria), were the first to make language to communicate.
