At one point in time, everything was made of stone: axes, spear, arrowhead, tables and chairs. The Stone Age was far longer than a century it lasted for almost 2 million 6 hundred thousand years. At that time the earth wasn’t roamed by people as we know them today, but our ancestors already knew how to make very basic tools and their time of existence was known as the stone age which ended only some 8-6 thousand years ago.
