Let’s imagine one of the first human beings on earth. Imagine a man named Joe. When Joe looks at his hand, he saw that it was different than the bear’s paw or a deer’s hoot. The 2-5-fingers and 1-thumb hands of the man allowed him to be able to grab hold of things and many more. So, one day, Joe realized that he could do more with his hand than any other animal on earth. Another thing he realized was that the other animals could not think as fast as he could. That’s how Joe knew that even though he didn’t have a fur coat or sharp teeth or claws like the animals, he can survive with his hands and understanding of the things around him. Joe realized that he could do so many things with his hands and mind which made him smile. He was so thrilled with the discovery that he laughed out loud and wanted to tell to his friends about his new idea.
