The first two questions face anyone who cares to distinguish the real from the unreal and the true from the false. The third question faces anyone who makes any decisions at all, and even not deciding is itself a decision.
Hominids started using primitive stone tools millions of years ago. The earliest stone tools were little more than a fractured rock, but approximately 75, years ago,  pressure flaking provided a way to make much finer work.
Control of fire by early humans The discovery and utilization of firea simple energy source with many profound uses, was a turning point in the technological evolution of humankind. As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as ka, humans were constructing temporary wood huts.
The invention of polished stone axes was a major advance that allowed forest clearance on a large scale to create farms.
This use of polished stone axes increased greatly in the Neolithic, but were originally used in the preceding Mesolithic in some areas such as Ireland. Additionally, children could contribute labor to the raising of crops more readily than they could to the hunter-gatherer economy.
Eventually, the working of metals led to the discovery of alloys such as bronze and brass about BCE. The first uses of iron alloys such as steel dates to around BCE.
History of transport Meanwhile, humans were learning to harness other forms of energy. The earliest known use of wind power is the sailing ship ; the earliest record of a ship under sail is that of a Nile boat dating to the 8th millennium BCE. The ancient Sumerians in Mesopotamia used a complex system of canals and levees to divert water from the Tigris and Euphrates rivers for irrigation.
More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia. It did not take long to discover that wheeled wagons could be used to carry heavy loads.
The first two-wheeled carts were derived from travois  and were first used in Mesopotamia and Iran in around BCE.

Medieval technology saw the use of simple machines such as the leverthe screwand the pulley being combined to form more complicated tools, such as the wheelbarrowwindmills and clocks. The Renaissance brought forth many of these innovations, including the printing press which facilitated the greater communication of knowledgeand technology became increasingly associated with sciencebeginning a cycle of mutual advancement.
The advancements in technology in this era allowed a more steady supply of food, followed by the wider availability of consumer goods. The automobile revolutionized personal transportation. Starting in the United Kingdom in the 18th century, the Industrial Revolution was a period of great technological discovery, particularly in the areas of agriculturemanufacturingminingmetallurgyand transportdriven by the discovery of steam power.
Technology took another step in a second industrial revolution with the harnessing of electricity to create such innovations as the electric motorlight bulband countless others.
Scientific advancement and the discovery of new concepts later allowed for powered flight and advancements in medicinechemistryphysicsand engineering. The rise in technology has led to skyscrapers and broad urban areas whose inhabitants rely on motors to transport them and their food supply.
