There are some who would say that the safety pin is one of the most important inventions....especially for children for many years before Pampers. Another one would be the paper clip. How about scissors now there's something that many of us could not live without. As others have said before me there is not just one thing that can be considered the most important for in one way or another they are all inner active. For example, to have electricity in your home you also need electric power plants, wire, light poles. Seems like a never ending circle.
