Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth.
In 1972 this assumption was shown to be highly questionable.

It's never used for non-organic samples, and almost never even attempted if the sample is thought to be much older than about 50,000 years.Let us critically examine each of these claims and see if they hold up against the science.While doing so, we will have to learn about how radiometric dating works.There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.
