We could cherry pick individual songs that some may say was the start. Helter Skelter and even Everybody's Got Something to Hide Except Me and My Monkey, both on the White Album. An argument can be made that the Tielman Brothers invented heavy metal posturing. There is just too many little things that pre-dated Sabbath to say they started the genre.
That's my point though, there's always an evolution of sound but no one in their right mind would ever say "Helter Skelter" was a metal song.
