Question

Prehistory The prehistoric period is the time
when writing had not been invented. Hence,
there are no written records of this period.
Our knowledge of prehistory is based entirely
on archaeology. To understand prehistory,
archaeologists dig deep into the ground and
dig out the remains of the past. These physical
remains such as pots, jewellery, tools, coins,
bones, etc. help them to know about the past.
Imagine You are living at a time when there
is no written or spoken language. How will
you express your ideas to your friends? Try
enacting a play or skit in class.​

Answer:

Human prehistory, also known as pre-literary history[1], is the period between the use of the first stone tools by hominins c. 3.3 million years ago and the invention of writing systems. The use of symbols, marks, and images appears very early among humans, but the earliest known writing systems appeared c. 5,300 years ago and it took thousands of years for writing systems to be widely adopted. In some human cultures, writing systems were not used until the nineteenth century and, in a few, not even until the present. The end of prehistory therefore came at very different dates in different places, and the term is less often used in discussing societies where prehistory ended relatively recently.

Sumer in Mesopotamia, the Indus valley civilization, and ancient Egypt were the first civilizations to develop their own scripts and to keep historical records; this took place already during the early Bronze Age. Neighboring civilizations were the first to follow. Most other civilizations reached the end of prehistory during the Iron Age. The three-age system of division of prehistory into the Stone Age, followed by the Bronze Age and Iron Age, remains in use for much of Eurasia and North Africa, but is not generally used in those parts of the world where the working of hard metals arrived abruptly from contact with Eurasian cultures, such as Oceania, Australasia, much of Sub-Saharan Africa, and parts of the Americas. With some exceptions in Pre-Columbian civilizations in the Americas, these areas did not develop complex writing systems before the arrival of Eurasians, so their prehistory reaches into relatively recent periods; for example, 1788 is usually taken as the end of the prehistory of Australia.
