How insignificant is the human race?

One of the best ways to understand the relation between the earth and all that exists on it is to imagine that the earth is 46 years old. And when we write her life history, we find that we know nothing about the first seven years of her life, but the deeds of her later childhood are to be seen in the old rocks.

Most of what we recognise on earth, including all substantial life is the product of the last six years of its life(i.e 600 m.y). She flowered, in her middle age. Her continents were quite bare of its life till she was almost 42 and flowering plants did not appear until she was 45 - just a year ago. At that time the great reptiles, including the dinosaurs, came into existence and the breakup of the last supercontinent was in progress.

The dinosaurs passed away eight months ago and the early mammal replaced them. In the middle of last week, in Africa, some manlike apes developed into apelike man and at the weekend mother earth began shivering with the latest series of extremely cold ice-ages. Just over four hours have elapsed since a new species HomoSapiens came into existence and in the last hour it invented agriculture and settled down.Just about 30 minutes back the pre-harappan and early harappan cultures started developing. Just about 14 minutes back, Buddha delivered his first sermon at sarnath, and the Mauryan empire flourished 12 minutes back. Harsha gave all, whatever he had, the religious assembly at prayag about 7 minutes back, and Akbar made a pilgrimage to sufi saint Salim Chisti just about 2 minutes back. India became a proud independent nation hardly two seconds back.
