The term for the period of time before written records is known as prehistory. This era encompasses all human history prior to the invention of writing systems, which varies by region but generally includes thousands of years. Prehistory is typically divided into several stages, including the Stone Age, Bronze Age, and Iron Age, each characterized by technological and social advancements. Archaeology plays a crucial role in studying this period, as artifacts, fossils, and other remnants of past cultures provide insight into early human life, societies, and behaviors. Understanding prehistory helps contextualize human development and the progression toward written history.
