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

Bronze is made from copper and tin, copper and tin have a much lower melting temp compaired to iron so it was easier to work with until they could make fires hot enough to melt iron
