История техники начинается с использования первобытными людьми каменных инструментов. В древности, около 2.5 миллионов лет назад, производились каменные инструменты, использовались огонь, копья, луки и стрелы и простые масляные лампы. В эпоху неолита, около 90000 до н.э., появилось сельское хозяйство, использовались роющие палки и деревянные мотыги. Каменные инструменты улучшились и для срубки деревьев использовались каменные топоры. Люди неолита создавали горшки, ткань, корзины, строили дома и лодки.
