GENERAL KNOWLEDGE

Detailed explanation-1: -Copper was first used by man over 10, 000 years ago. A copper pendant discovered in what is now northern Iraq has been dated about 8700 B.C. For nearly five millennia copper was the only metal known to man, and thus had all the metal applications.

Detailed explanation-2: -The first metal to be extensively used by the people in India was copper. Archaeological evidence suggests that copper was first used between 8, 000 and 5, 000 B.C., most likely in the regions known now as Turkey, Iran, Iraq and toward the end of that period the Indian subcontinent.

Detailed explanation-3: -Between seven and ten thousand years ago, our early ancestors discovered that copper is malleable, holds a sharp edge, and could be fashioned into tools, ornaments, and weapons more easily than stone, a discovery that would change humanity forever.
