Scientific methods of dating the earth
In fact, the other 139 crystals show such a confusion of information that a statistician could only conclude that no sensible dates could be extracted from the data. They extracted diamonds from rocks in Zaire and found by the potassium-argon method that they (the diamonds) were six billion years old.
A further problem is that the 4.3 billion-year-old zircon, dated according to the U/U method, was identified by the U/Th method to be undatable. But the earth is supposed to be only 4.5 billion years old. They admitted, however, that if the date had not been contradicted by the ‘known’ age of the earth, they would have accepted it as valid.
We often test them under controlled conditions to learn when and why they fail so we will not use them incorrectly. For example, after extensive testing over many years, it was concluded that uranium-helium dating is highly unreliable because the small helium atom diffuses easily out of minerals over geologic time.
No statistician could ever condone a method which selected one value and discarded all the other 139. They found what might have been the world’s oldest rock crystals, but unfortunately they were too old!Where are the data and age calculations that result in a consistent set of ages for all rocks on earth, as well as those from the moon and the meteorites, no greater than 10 000 years? Second, it is an approach doomed to failure at the outset.
