Over the many years we humans have been alive many great things have been achieved. As a species we have used our brain not our strength to over power our struggles and obstacles. We have come so far since from our humble caveman begins to the digitally intelligent people we are today.
I think there are few areas where we have really shined and bettered ourselves, which are: science, medicine and technology.
In the beginning Humans used tools to do daily activities like hunting and cooking. Tools were also used to create objects and machines. Machines, which have let us fly, entertain, travel, kill and save lives. Technology lets us do things Humans can't do naturally but in science we learn how things work.
Science enables us as Humans to understand the world, why it does what it does and how does it. The knowledge of how things work helps us improve the world and avoid things that can be prevented. Machines can be enhanced and things can be created with the understanding of science and the world. The secrets of the body can also be understood therefore saving peoples lives and curing the once incurable.
