Quote by Jamal Nazrul Islam

“It is perhaps worth noticing that we have arrived 'on the scene' at a fairly early date. By this I mean that the time scale that it has taken nature to create us is of the same order of magnitude as the age of the universe. The universe is about 10-15 billion years old, and the Earth about 4.5 billion years old. Life is supposed to have begun on Earth about 3 billion years ago. It would not have been possible to evolve life, because of the hostile conditions, in the first few billion years after the big bang. Thus we have been created almost as soon as the universe was in a position to create us. It is an interesting question how long the universe will continue to create entirely new forms of life, assuming that it is open.”
