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.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.
Just like calibrating an hourglass, where sand falls at a constant rate, experimental observers might begin by trying to count directly how much sand falls each second (i.e. If 1 gram of sand falls per second, and the hourglass contains 3.6 kg of sand, then it should take exactly 1 hour (3,600 seconds) for all the sand to drain from top to bottom.
Once this rate is observed over a limited period of time, we can test the accuracy of our observation by extrapolation and/or comparing it to other timekeeping methods, such as a sundial.
This is like the common phrase that Christians like to use when studying the Bible, when we say, "He pulled that out of context." When considering the date of the world, and the universe, you have to consider all the evidence, not just one portion.
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.

One of the key assumptions in radiometric dating is that we can know how fast the radioactive parent element decays into the radiogenic daughter element.
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.
Confusion of these terms is a sure sign of geological ignorance.
ICR creationists claim that this discredits C-14 dating. Answer: It does discredit the C-14 dating of freshwater mussels, but that's about all.
Kieth and Anderson show considerable evidence that the mussels acquired much of their carbon from the limestone of the waters they lived in and from some very old humus as well.
Their motivation is obvious: all techniques consistently yield age estimates far older than the purported So where to start?Tags: Adult Dating, affair dating, sex dating
