Early human history can be dated back to the Stone Age in the Palaeolithic period (2.5 million years ago – till 10,000 BCE) when early man followed nomadic ways of the hunter-gatherer, lived in caves and huts or tepees and had begun to develop rudimentary tools of stone and wood.
Detailed Explanation
In the beginning of human history, during the Stone Age, people lived nomadically. This means they moved around often, hunting and gathering food rather than settling in one place. They built simple shelters like caves or huts. During this time, humans started to make basic tools using stones and wood, which laid the foundation for future developments in building and civil engineering.
Examples & Analogies
Imagine a camping trip where you set up a tent in the woods. Just like the early humans who needed to create a safe place to stay while hunting for food, you build your tent to protect yourself from the weather. The tools you use, like a hammer or knife, are similar to the rudimentary tools early humans created.
Agricultural Shift and Settlements

But around 10,000 BCE, a shift in climate and discovery of farming led the Neolithic man to settle, mostly along riverbanks, with focus on production of food. This in turn, led to the need to build secure habitation, plan settlements, and land use, construct transport and irrigation systems, and design solutions towards water supply and sanitation, which can be identified as the first examples of civil engineering.
Detailed Explanation
Around 10,000 BCE, a significant change occurred when humans discovered farming and began to cultivate land. With farming, people could produce their own food, allowing them to settle in one area, primarily near rivers for easy access to water. This led to the development of secure homes, organized settlements, and the need for systems to transport water and manage agriculture, which are all early forms of civil engineering.
Examples & Analogies
Think about starting a garden at home. When you decide to plant vegetables, you first build a fence to protect your plants and create a watering system to ensure they grow. Just like you plan your garden, early humans planned their settlements to improve their lives and support farming.
