Other methods must be used to estimate the age of rocks and minerals.acquired trait: A phenotypic characteristic, acquired during growth and development, that is not genetically based and therefore cannot be passed on to the next generation (for example, the large muscles of a weightlifter).Evolutionism, of course, requires billions of years to support the plausibility of life's emergence and of subsequent Evolution from “amoeba” to man.Theoretically, Creationism remains workable within a wide range of age estimates.Various radioactive elements are involved, including Carbon-14, Uranium-238, Thorium-232, and Potassium-40.By the way, it is important to understand that most rock strata “dates” were actually assigned long before the first use of radioactive age estimating methods in 1911.However, by itself a fossil has little meaning unless it is placed within some context.

’ s first definition, a “skeptic” is “one who holds that there are no adequate grounds for certainty as to the truth of any proposition whatever.” This is too nihilistic.

The Carbon-14 age estimating method is, at best, only useful for estimating the age of things that are thousands of years old, not millions or billions.

And it does not work on rocks or thoroughly mineralized fossils; it is only useful for relatively well-preserved organic materials such as cloth, wood, and other non-fossilized materials.

Then there are negative truths, such as the null hypothesis in science, which asserts that particular associations do not exist unless proved otherwise.

For example, it is telling that among the tens of thousands of government e-mails, documents and files leaked in recent years, there is not one indication of a UFO cover-up or faked moon landing or allegation that 9/11 was an inside job by the Bush administration.
