Necessity is the mother of inventions

We have heard many times that necessity is the mother of inventions in our surroundings. If I say this statement is true to some extent it will not be wrong. Human behavior and the human mind are in a continuous process of doing something new, creating something new, exploring new things, experimenting the knowledge humans have got. But, we also cannot deny this fact that whatever comes into being, new scientific invention is a result of a need. We are in a circle of needs and wants. Our needs are what we basically need, our basics of life. And our wants refer to our emotions rather than needs. What we see other people have, we demand that for us too. But needs are more important as one can live without wants but cannot without needs. Our basic needs are air, water, food, clothing and shelter. If we go back to the Stone Age era where when humans started mingling over they created the things regarding their needs. One explored how to make fire by rubbing stones, one explored how to cover the body with leaves, another explored means of food, then shelter and this continued for years. With the evolution of time and space, needs became more and more so the human mind kept on exploring new ideas that came into his mind. Today we live in a mechanical life where needs are increasing day by day so are the inventions. We have the whole world in our hands. We are in the cyber world. So in this 21st century humans have made many inventions as per needs. So we cannot deny the fact that necessity is the mother of all inventions we have in our hands.
