The first language existed with the first people. Humans speak, it's one of our defining characteristics. Unfortunately, exactly when and were speech develops before that - unclear.
No one "makes" languages. as the prior poster's links say, language just is. It grows and changes over time. English is an anglo saxon language that was strongly influence by French, Spanish, and through the sciences, Greek and Latin. Anglo-Saxon languages are from the Germanic family, and beyond that belong to an even older family called the "indo Europeans" that includes the romances (french, latin, spanish, italian, etc), greek, cyrillic and hindu.
