In the starting of human civilization like Indus valley civilization the metal firstly used by man was copper, that time iron and gold were not known to those men. It is the starting metal of human civilization.

Cu is first using metal at the time none of the metal can discovered by human.

Indian history Cu period is 1st one.

But when we read history there is no copper age there is bronze age. So answer must be bronze.

Ya it is true that bronze is the other name of copper but according to question answer must be bronze not copper.

According to history of India Bronze is the 1st.

Bronze is not a pure metal. (Cu+Zn) impossible.

That's why Indus valley civilization is sometimes known as cathodic age.

If we saw the history bronze is 1st than copper.

Pranay said: (Sep 17, 2016)  
I think bronze is the answer.

Biafran said: (Dec 4, 2016)  
I think bronze is the answer because we have many histories of a man with man.

Bronze is an alloy not a metal.

Ammu said: (Mar 21, 2017)  
Copper is correct, bronze is an alloy of mainly cu.

Bronze in is not a pure metal.

It's Cu +Zn. The Harappan culture uses many underground things made of copper. So copper is the right answer.
