Question

why did the early man feel the need to write and draw​

Answer 1

Answer:

By drawing something, an early human could make another human remember something. Various forms of drawing, painting, and other visual depictions almost certainly facilitated communication and education among early humans. That much seems rather obvious.

Answer 2

Answer:

While not all human cultures have needed to develop writing, we appear to have been using signs to communicate with each other, or simply to help remember things, for tens of thousands of years. In ancient times we find engraved or painted marks on the walls of human dwellings, portable objects and mnemonic devices. And today, we engage in similar mark-making.
