Similarly, there is no way that it can be proved that these radioactive systems have been closed through all the supposed millions of years of decay of parent isotopes into daughter isotopes.Again, the main reason for this is because no scientist has been present to observe everywhere these radioactive systems and so report that they have been closed through all their history.However, not all meteorites have the same uraniumthorium- lead isotopic composition, so why should the isotopic composition of these particular meteorites be considered to be the ‘correct’ composition for the earth at its origin rather than some other composition found in other meteorites?Furthermore, even if today’s scientists believe they have the methods, for example graphical and mathematical, for determining how much of the daughter isotope might have been present either at the origin of the earth or the origin of the rock being dated, no one can ever be sure that these ‘answers’ are correct, because there was no scientist present at the beginning to observe those initial conditions, even though the scientists’ calculations may be extremely logical.This in turn allows the evidence for a young earth and universe1 to ‘speak’ more loudly in support of the scriptural chronology of a 6,000-7,000 year age, which of course leaves no time for any ‘big bang’ and ‘molecules-to-man’ evolutionary scenarios.
However, in the case of these radioactive ‘clocks’ these three assumptions can be shown to be not only unprovable, but invalid, rendering these ‘clocks’ virtually useless.
Now this ‘clock’ works because the initial conditions are known—that is, all the sand grains are in the top glass bowl and none are in the bottom one.
If there is already some sand in the bottom glass bowl, then unless this amount is known the hourglass ‘clock’ cannot ‘tell’ the time.
Thus the first step in the radioactive dating technique is to measure the amounts of the parent and daughter elements (isotopes) in a rock sample via chemical analyses.
This is done in specially equipped laboratories with sophisticated instruments capable of very good precision and accuracy, so in general there is no quarrel with the resulting chemical analyses.

Or, some uranium might have been deposited by groundwaters into the sample, thus making it appear younger than what it really is.
