The first metal used by humans was copper. Early humans began using copper around 10,000 years ago, during the Chalcolithic period (the Copper Age). Initially, they used naturally occurring copper in its pure form, which was soft and easy to shape. Over time, humans discovered how to melt and cast copper, leading to the creation of tools, weapons, and ornaments. Copper was significant because it marked the beginning of metalworking, which paved the way for the development of other metals like bronze and iron.
