" The greatest gift that humans have is the ability to think. Of all the creatures in the world, humans are physically the most ill-equipped. A human cannot fly like a bird, outrun a leopard, swim like an alligator, nor climb trees like a monkey. A human doesn’t have the eyes of an eagle, nor the claws and teeth of a wild cat. Physically, humans are helpless and defenseless; a tiny insect can kill them. But nature is reasonable and kind. Nature’s greatest gift to humankind is the ability to think. Humans can create their own environment, whereas animals have to adapt to their environment. "
