If you base your rejection of 60,000 years on the ridiculousness of the population size of 5 trillion, then you should also reconsider, based on the population if mice, an age of 6000 years for the earth. With a current world population of about 4 billion mice it is obvious that the world could not have been created before August 27, 2009.
