Eli5 why did the Bronze Age happen before the Iron Age?

Question

I would have thought that with bronze being an alloy it would have been more difficult to work with than iron, so why was it the first to become widely used?

In: 2489

Answer 1

Because bronze has a lower melting point. Iron melts at about 1500C, Bronze at about 1000C. There are other metals that melt at lower points but they have other undesired properties, mostly they are to soft to make tools out of them.
