To understandhow the Earth started; we need to start off with origins of mankind and the earth's existence. The Earth came into existence about 6 billion years ago and the emergence of homo-sapiens-sapiens 200,000 years ago. Technology has always been closely linked to the way in which people have lived. Before the development of civilizations, humans lived for many millennia with tools and techniques that allowed them to live successfully in wide variety environments. Following this development, civilization started to arise. Through discoveries of the ancient world, we can understand the lifestyle and how these humans have grown together. Prehistoric humans developed technologies and ways of life that allowed them to increase their control over the natural world.
             To interpret the entire breadth of human existence, vast lengths of time are required. Once we enter prehistoric time, we are dealing with hundred and thousands of years. To make sense of this time scale, we start off with the first, and most ancient, the Paleolithic Age. The term Paleolithic means "old stone" and gives an indication of how things were related to human existence. This era in history begins somewhere between 2 million years ago and ends 10,000 years before our time. It marks the beginning of the existence of the ancestors of man, the homo-sapiens sapiens. The Paleolithic people were brought up on hunting, gathering, and fishing. In search of the new food sources and to be able to hunt animals, they moved from place to place, and gathered in small groups. The dwellings of these people were normally in rocky areas. Starting around 40,000 BCE, the Paleolithic people started making simple stone tools for hunting and protection purposes. Not being able to move much due to the glacial age climate, the primitive man utilized the skin of the animals. During this time of survival, the Paleolithic people were able to discover and control fire, in ...
