[ELI5] Who made the first Blacksmithing tools?

I've recently watched a video of Tom Scott on his second channel where he made (with the help of a blacksmith) make a bottle opener.


The guy first made Tom to blacksmith a punch or whatever then he mentioned that "Blacksmiths had to make their own tools"  or something among the lines anyways.


So it struck me. How did people make their first tools? Are there any records? Or were people just banging rocks to the metal, made a primitive sledgehammer then used that further on?


How did they even came up with the idea that if you put metal in fire you can *remodel* it?

Metal would naturally find its way into man made fires either by putting a rock or heating some sort of ceramics that contained metal in them. Depending on the metal, we'd visually see it turning into liquid (as a result of the heat) and then solidifying when it cooled.
