Assumptions behind radiometric dating

This is because 40Ar is an inert gas that does not combine chemically with any other element and so escapes easily from rocks when they are heated.Thus, while a rock is molten, the 40Ar formed by the decay of 40K escapes from the liquid.Well, for many former and even current Seventh-day Adventists, radiometric dating of the rocks of the Earth presents a serious problem when compared to the apparent claims of the Bible regarding a literal 7-day creation week – and many have voiced such concerns over the years (Link).

It is also quite clear that these authors were actually trying to convey a literal historical narrative – not an allegory.

They actually believed that what they wrote was literal history.

One of the many reasons that I’ve come to this conclusion is that I’ve studied the claims of many Biblical critics for most of my adult life, to include the very popular claims of the modern neo-Darwinian scientists, and I’ve found them to be either very weak or downright untenable – and this includes the popular claims regarding radiometric dating methods in general, which will be the focus of this particular discussion.

All radiometric dating methods are based on one basic concept.

Because of this feature where only the parent product starts off in a solidifying rock, and because of its relative abundance within the rocks of the Earth, the K-Ar dating method is by far the most popular in use today. Experimental studies done on numerous modern volcanoes with historically known eruption times have been evaluated.

Around 85% of the time, the K-Ar method of dating is used to date various basaltic rocks from around the world. In any case, the logic for calculating elapsed time here appears to be both simple and straightforward (see formula for the calculation). And, about a third of the igneous rocks from these volcanoes show a bit of extra Ar to make the clock look older by a few hundred thousand to, rarely, up to a couple million years.

And, these radiometric “clocks” certainly appear to show that living things have in fact existed and changed dramatically on this planet over very very long periods of time indeed!

So, why is this a problem for so many within the church?

Well, for one thing, it is the only radiometric dating method where the “parent”, or starting radioactive “isotope” or element in a volcanic rock or crystal, can be pure – without any “daughter” or product isotope already present within the rock or crystal that one is trying to date.
