The Stone Age lasted from 30,000 BCE to about 3,000 BCE and is named after the main technological tool developed at that time: stone. It ended with the advent of the Bronze Age and Iron Age .

Why is the age before 3000 BC called as the stone age?
The period before 3000 BC is known as the Stone Age due to the predominant use of stone tools by early human societies. Let's delve deeper into why this era is named as such:
- Development of Technology:
During the Stone Age, humans primarily used tools made out of stone, such as axes, spears, and knives. These tools were crafted by chipping, knapping, or grinding stones to create sharp edges for various purposes like hunting, cooking, and building shelters.
- Lack of Metal Usage:
One of the defining characteristics of the Stone Age is the absence of metal tools. Early humans had not yet discovered the techniques for extracting and working with metals like copper, bronze, and iron, which would later mark the beginning of the Bronze Age and Iron Age.
- Chronological Classification:
Archaeologists divide human history into different periods based on technological advancements and cultural developments. The Stone Age is further classified into the Paleolithic, Mesolithic, and Neolithic periods, each representing a stage of human progress in tool-making, social organization, and adaptation to the environment.
- Stone Tools as Cultural Markers:
The extensive use of stone tools during this era not only shaped early human societies but also left a lasting impact on archaeological records. Stone artifacts serve as valuable clues for understanding the lifestyles, beliefs, and interactions of ancient civilizations.
In conclusion, the age before 3000 BC is referred to as the Stone Age because of the widespread reliance on stone tools, the absence of metal technology, and its significance in the evolution of human culture and technology.
