::I wouldn't accept that it is nitpicking. When I looked up info on some of the variations in decay rate that have been identified, none of them would make a significant difference to the magnitude of the time periods involved. None of them would explain the gap between 6,000-10,000 years old and the billions of years at the other end of the scale. They impact on the precision, not the reliability. That isn't to say there aren't other problems in assuming decay rate is a good way of determining the age of the earth but the possibility of variation in decay rate identified don't support the suggestion that what is known about decay is so wrong that the the figures calculated from it could be millions of times out. The facts as to the known variation of radioactive decay just don't support that. [[User:Adambro|Adambro]] 18:58, 10 January 2012 (EST)
