I think "Paper" would be the best invention created by man. From papers to books. We all know that even in this generation paper is an important tool used throughout the history of the world. Papers were used by different people for different purposes especially to learn different things of information and knowledge.. Ideas came from well-known people throughout the history and if paper wasn't invented, bright and innovative ideas will never be recorded and it would be impossible to our finest inventors,scientists,scholars,philosophers and even historians for them to record every theories and ideas that helped our way of life more easier. Thanks to the chinese during the Han Dynasty for these wonderful discovery. Imagine if they never invented paper and we are still in the stone age era.
