Four assumptions that underlie radiometric dating methods

There are at least 67 different uniformitarian (the present is the key to the past) methods of dating the earth other than long-age radiometric dating: each of which yield ages of less than 500 million years.

Yet all these other science-based methods that point to a much younger age than 4.5 billion years for earth's age are ignored or rejected by evolution-believing people with degrees from college who apparently think that nobody (of importance) made them. Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth's age many years ago.

In many cases it is quite difficult to prove whether one method is superior to another: and in this regard, the only way of doing so is to closely examine how each method works and try to find fault with it.

In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.

In this regard, pro-evolution scientists are very selective about which dates they accept and which ones they reject: such as any date that is contrary to the Geological Time Chart -- to which all radiometric dates must fall in line with.

They did this because it is almost certain that these lead isotopes were all present in large quantities when the earth was created.

With the exception of Carbon-14, radiometric dating is used to date either igneous or metamorphic rocks that contain radioactive elements such as uranium, thorium, argon, etc. Now when the uranium or thorium disintegrates, the alpha particles which are emitted are slowed down by the crystals in which the grains of the uranium- or thorium-bearing minerals are embedded.

And even though various radioactive elements have been used to 'date' such rocks, for the most part, the methods are the same. This means that if you had some pure uranium-238 with no lead, that 4.5 billion years later, one half of it would have decayed into its stable daughter product (lead-206). Where these alpha particles finally stop, crystal deformation occurs (and) shows up as a discolouration or a darkening of the crystals.

Therefore, if a scientist has strong beliefs about this topic, he or she will tend to be biased against any evidence that contradicts their beliefs with regard to the earth's reported age: of 4.5 billion years. that (the) half-lives (of uranium-thorium-lead) are not constant but vary with time. comes from the study of pleochroic haloes which form in a rock in the following way.

For example, the 67 ( ) other methods of dating the earth, solar system, and/or universe. When a rock crystallises, the crystals of the minerals in the rock often enclose minute grains of other minerals which contain uranium and thorium.
