Early humans on planet Earth were nomads. They were hunter-gathers and also ate berries and nuts as part of their daily diet. Their clothes were from animal skins. They continually migrated from place to place because they were following animal herds with the change of seasons. They had to learn how to survive under harsh weather conditions. It was only until the Stone Age where humans learn to construct tools such as spears and daggers.
