gave us ample reason to believe that radiometric dating of meteorites is solid. By dating certain types of meteorites, geologists arrive at the most precise age estimate of our Earth: 4.56 billion years.
One may try to dispute whether the Earth formed simultaneously with these meteorites (we have strong reason to believe it did), since the oldest minerals that we can date directly are only ~4.3 billion years old.
I can look in my scientific journals and see apparent discrepancies in dating techniques.
Some may be discrepancies…some may just need a bit further explanation.
Regardless, even Snelling recognizes that multiple independent methods consistently tell us the Earth is billions—The grains of sand have to pass one after another, therefore time exists.

Before I begin, there is one set of terms you should be able to distinguish: radiometric dating is a method of estimating the age of geological events using radioactive isotopes in minerals; radioactive dating occurs in the storage room at the nuclear power plant and has very little to do with geology.
We take the radiometric dates, along with stratigraphy (I know, dated radiometrically), the specific fossil species in a rock (I know, dated radiometrically) and come up with a date. Because although not perfect, it is the best tool we have.But whatever your passion for decaying metals and your level of chemical comprehension is now, I want to share my confidence that you can follow along just fine.Anyone can learn technical jargon (queue Wikipedia page for Potassium Argon Dating); reading this post only requires a knack for scientific reasoning.The older an organism's remains are, the less beta radiation it emits because its C-14 is steadily dwindling at a predictable rate.So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. Question: Kieth and Anderson radiocarbon-dated the shell of a living freshwater mussel and obtained an age of over two thousand years.
