As we pointed out in these two articles, radiometric dates are based on known rates of radioactivity, a phenomenon that is rooted in fundamental laws of physics and follows simple mathematical formulas.

Dating schemes based on rates of radioactivity have been refined and scrutinized for several decades.

Radioactive decay rates have been measured for over sixty years now for many of the decay clocks without any observed changes.

Technical details on how these dates are calculated are given in Radiometric dating. As with any experimental procedure in any field of science, these measurements are subject to certain "glitches" and "anomalies," as noted in the literature.

The differences actually found in the scientific literature are usually close to the margin of error, usually a few percent, not orders of magnitude!

Vast amounts of data overwhelmingly favor an old Earth.

Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years.

Essentially all of these strongly favor an old Earth.
