Human beings are a creative species. They have thought of and invented some really amazing things that transformed the way of living on the earth. From the moment someone rolled a wheel prototype on the ground to make the first nail, to the introduction of the compass to the development of super-fast motor cars and Artificial Intelligence, several important inventions stand out as ground-breaking that really changed the world. They have opened the door to a completely new era in human history. Here is our list of a few such inventions that changed the world. These inventions have shaped civilizations and gave wings to human capabilities. Most of these inventions don’t have just one man behind them. Sometimes they have been developed by many creative minds giving it completely different shape and usages. Now it would be almost impossible to think of leading a normal life without some of these inventions.
