It all started from the cavemen beating on rocks to create entertainment. Then...people started using there voices to get messages across in music form. Then...people made instruments designed to produce certain sounds (such as guitars, bass, flutes, blah). THEN bands were made after choirs. THEN sounds started to progress and metal comes from bands that aimed to be heavier/faster/technical. So it didn't really "start" with a specific person. I'd say big influences would be beatles, dio, ozzy, venom, iron maiden, judas priest, and accept. But they didn't create metal.
