The Stone Age in Ireland was divided into three parts: the Early Stone Age, Middle Stone Age, and New Stone Age. During this time, the first people arrived in Ireland around 9,000 years ago and hunted animals, fished, and gathered food. They made tools from wood and stone to help with hunting and fishing. Later, more people came who practiced farming and were Ireland's first farmers, allowing people to settle in one place rather than constantly searching for food. During the New Stone Age, Ireland was covered in forests, and farmers cut down trees to make space for houses and farms, growing crops and raising animals.
