What historical period is defined by the advent of bronze-making around 4000 years ago?

Alright, let's talk about the Bronze Age. Think of it as a major turning point in human history, specifically around 4,000 years ago. Before this, people primarily used stone for tools and weapons – that was the Stone Age, obviously! But then, someone figured out how to mix copper and tin to create bronze, a much stronger and more durable metal. This was a game-changer! Suddenly, you could make better tools for farming, more effective weapons for warfare, and even decorative items. This new technology spread, and societies that mastered bronze production gained a significant advantage. So, when we talk about the period defined by the introduction and widespread use of bronze, we're specifically referring to the Bronze Age. The Iron Age came later, after people learned how to smelt iron, which is even stronger than bronze. So, while the Stone Age and Iron Age are important periods, the question specifically asks about the advent of bronze-making, which is the defining characteristic of the Bronze Age.
