Just keep mining. You will eventually find iron ore which you can mine with your stone pickaxe. It may take a while, but the deeper you go the higher the chance of finding iron. It's there, you just have to find it. Once you do, build a furnace and put your iron in the top and coal in the bottom and your iron will smelt into ingots, which you can use to make all sorts of nifty things.
