THE GODS GAVE US FIRE, BUT WE MAD OURSELVES GODS WITH METAL.
As far as I know (and I may be wrong) gods gave us fire via Prometheus, but man invented metal. And while Hephaestus is a god of Smiths (and I am not sure how many civilizations have such a thing other than Thor and Hephaestus) the gods did not give man metal. We made our solves gods by discovering it, and bending it to our will. 😉
