The Pangaea super-continent broke up into tectonic plates and these moved into their approximate current locations over the space of a centuries. How do we know? By studying paleomagnetism.
As simple and convenient the young Earth creation (YEC) variable rate of nuclear decay response to radiometric dating may be, it's also an Achilles Heel.
There was enough water in the great deep to flood the Earth 1,200 km deep. 15 cubits was when the crew of the ark stopped taking soundings. Mount Everest formed 101 years AFTER Noah's flood during Peleg's tectonics.
People presume to disprove God by cobbling together some math based on Uniformitarianism ideals that were popularized by Charles Lyell, a contemporary of Charles Darwin.
It's impossible to prove that radioisotopes have always decayed at a constant rate throughout history, since the ability to detect and measure radioactive decay is only about 120 years old.
Atheist science trolls (ASTs) think that they have the silver bullet which kills the Young Earth Creationist (YEC) belief that nuclear decay is variable and that it was initially rapid.
Radiometric dating is an example of inductive reductive circular reasoning. It requires the assumption that nuclear decay rates are constant and an unwarranted application of the half-life rate law to nuclear decay.
What do you really want out of life? Do you want to fool yourself with SciPop that there's no hell so that you can live this fraught and miserable existence and end up in it?
If the theory of evolution was the centerpiece of the popular science narrative of godless existence (SciPop), then radiometric dating was the pseudoscientific glue which held it together.
The decay constant is a fictional contrivance necessary for the popular science (SciPop) rationalization of the geological timescale and the age of the Earth. It's critical to the SciPop claim that there's no hell.
