Where did the art of metallurgy begin?

The art of Metallurgy began in ancient Mesopotamia, around 4000 BCE, where early humans first discovered how to extract metals from their ores. Initially, copper was the primary metal used, leading to the development of tools and weapons. This innovation spread to other regions, including Egypt and the Indus Valley, marking the transition from the Stone Age to the Metal Age, particularly with the introduction of bronze through the alloying of copper and tin.
