#5 – Steam Engine
None of the existing transportation methods that you can see around you would ever be possible if the steam engine hadn’t been invented. More importantly, you wouldn’t have supermarkets and large quantities of foods, drinks, and clothes everywhere if it wasn’t for this innovation. Prior to the steam engine, everything was made by hand. It is enough to say that it had such an impact on the human society that it sparked the Industrial Revolution. After that, large factories started opening, and the rest is history.
