If early humans crafted a hammer or an axe from metal for example. How on earth did they craft the first tool that was used to create that hammer or axe. I know you can create a hammer from natural material like stone and an axe from a sharp piece of stone but how did they forge the first metal tools and even weapons?

Through pit kiln casting we got into the copper age. Basically, you take clay and mold it into the shape of the tool or tool head you need, then you bury it with silt and wood and shit and burn it for a long time. It’s insulated enough that it’ll get hot enough to melt the copper down. Then you let it cool, and chip away the clay mold, leaving just the tool head. It’s pretty easy to see how Neolithic tools were made if you consider they had pottery going (clay molding) for tens of thousands of years leading up to copper tools.
