Does a cat know he is a cat? Does a dog know he is a dog? Does nature know it is called nature? Does this planet know its name Earth? Does Sun know its name and its category as a star? Does Universe know that it is Universe? Does God knows that he is God? Well humans know their names and categorizations. Because this is the main objective of human life, to explore, to research, to give unique identity to unknown things in our native languages and to categorize them. This is the reason we are the only known species which are best for this job. Without us these things are nameless and with no categorization. So explore more and research more. Because this is the job we are assigned to in this organization called Universe.
