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 has a much lower melting point than iron, making it easier to work with and shape. The real difficulty was the logistics of sourcing all of the tin you needed; we still don’t entirely know where the Bronze Age civilizations got theirs.
