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 melts at cooler temperature than iron

So it’s easier to melt and forge bronze

It took several technological advances before we figured out how to heat up forges hot enough to melt iron
