But this graph won’t make an appearance in your recent issue of Creation Magazine or be highlighted on the Basic diagram of the crustal plates of the Earth and their general direction of motion.Plates are moving at different speeds with some moving away from each other and other running into each other."Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.We know that it is older than Christendom, but whether by a couple of years or a couple of centuries, or even by more than a millenium, we can do no more than guess." [Rasmus Nyerup, (Danish antiquarian), 1802 (in Trigger, 19)].The probability of a parent atom decaying in a fixed period of time is always the same for all atoms of that type regardless of temperature, pressure, or chemical conditions. The time required for one-half of any original number of parent atoms to decay is the half-life, which is related to the decay constant by a simple mathematical formula.

On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found.My last post, on the tectonic origins of the Dead Sea and Jordan Valley, brought me face-to-face once again with one of the most striking pieces of evidence for an ancient earth that I am aware of. This graph shows that the so-called historical sciences and observational sciences that Ken Ham touts can both reach the same conclusions. The data don’t reveal anything that hasn’t been common knowledge among geologists for a long time.These radioactive elements constitute independent clocks that allow geologists to determine the age of the rocks in which they occur.The radioactive parent elements used to date rocks and minerals are: Radiometric dating using the naturally-occurring radioactive elements is simple in concept even though technically complex.
