Sm nd isotopic dating
The supercontinent cycle, by which Earth history is seen as having been punctuated by the episodic assembly and breakup of supercontinents, has influenced the rock record more than any other geologic phenomena, and its recognition is arguably the most important advance in Earth Science since plate tectonics.
It documents fundamental aspects of the planet's interior dynamics and has charted the course of Earth's tectonic, climatic and biogeochemical evolution for billions of years.

This led the author of a report on the samples, Andrew Snelling, to conclude “and thus its present radioisotopic ratios do not provide its true age by the conventional radioisotope dating techniques.” The researchers explained away the obvious disagreement by claiming the older age was the time at which the rocks underwent metamorphism while the younger age resulted from a later heating of the rocks. The secularist will tell us that believing the biblical account of creation is not science, even though the preponderance of the observational evidence points to the truth of the Genesis record.
Unfortunately for them, secularists’ worldview of a matter, energy, random-chance universe (naturalism) is also a matter of belief, not science.
Do we believe God, whose Word has stood the test of time, or do we believe self-appointed experts who have a long history of mistaken ideas and bankrupt philosophies?

Secularist scientists want us to accept their circular arguments and improbable assumptions as scientific fact, despite the fact these same scientists often push aside the scientific method itself.
Using the various types of radioisotope decay as clocks does not produce consistent results, nor are those results verifiable by observational evidence.
Two isochrons from Grand Canyon’s Bass Rapid’s diabase sill and contact hornfels are discordant by a factor of 2—the diabase mineral isochron giving an age of 1376±140 Ma and the granophyre hornfels isochron giving an age of 676 ± 280 Ma. This is blind faith wrapped in a philosophical premise, not science.
