The point is that radiometric dating is not the sure thing that it has been made out to be over the last century.

Also remember that modern disasters (on a smaller scale) like Mount St.
Helens and Southwest Pacific tsunamis produced large deposits of multi-layered strata in a matter of hours or days… Yes, we all have been inundated with teaching that rocks are dated in the millions and billions of years, but are they really? Do they really NEED to be millions or billions of years old?
An examination of sedimentary rocks worldwide shows a striking consistency with the unimaginably massive Flood that wiped out whole environments.
It caused massive sedimentary layering and sorting and fossilizing of the creatures buried therein.
The resulting rock strata may harbor fossils from a particular habitat area or ecosystem, but do not represent a particular age or era.
Why else do we find marine fossils on the tops of all the major mountain ranges?
The time it takes for half of a sample to decay is called a “half-life.” By measuring radioactive half-lives, by measuring how much parent and daughter are present in any given specimen, and by making certain key assumptions, scientists believe they are able to accurately determine the age of a specimen. The question is what are the underlying key assumptions and how reliable are they?
The three key underlying assumptions are 1) the rate of decay of parent into daughter has remained constant throughout the unobservable past; 2) the specimen which we are examining hasn’t been contaminated in any way (that is, no parent or daughter has been added or taken away at any point during the unobservable past), and 3) we can determine how much parent and daughter were present at the beginning of the decay process – not all of the Pb206 present today necessarily came from decaying U238; Pb206 may have been part of the original constitution of the specimen.
Uranium-238 (U238), for example, is an unstable radioactive isotope which decays into Lead-206 (Pb206) naturally over time (it goes through 13 unstable intermediate stages before it finally stabilizes into Pb206).
