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

Copper and Tin were easier to work with. They have lower melting points, and can be cast into molds, for various things.

Iron at the time however, was a much more intensive task. It was abundant yes, but to heat it to a workable state was difficult, as the furnaces available weren’t hot enough.
