How importent are evolutionary dating methods
They generalized this observation to assert that the rate of evolutionary change of any specified protein was approximately constant over time and over different lineages (based on the molecular clock hypothesis (MCH)).
The genetic equidistance phenomenon was first noted in 1963 by Emanuel Margoliash, who wrote: "It appears that the number of residue differences between cytochrome c of any two species is mostly conditioned by the time elapsed since the lines of evolution leading to these two species originally diverged.
The molecular clock is a technique that uses the mutation rate of biomolecules to deduce the time in prehistory when two or more life forms diverged.
The biomolecular data used for such calculations are usually nucleotide sequences for DNA or amino acid sequences for proteins.
Here is scientific evidence that the 19 dating methods, used to establish ancient dates, are not accurate. We will here discuss the methods used by scientists today to date ancient substances.

Various radioactive elements are involved, including Carbon-14, Uranium-238, Thorium-232, and Potassium-40.
Uniformitarianism assumes that the vast amount of geological change recorded in the rocks is the product of slow and uniform processes operating over an immense span of time, as opposed to a global cataclysm of the type described in the Bible and other ancient texts.
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.
For example, a geologist may examine a cutting where the rocks appear as shown in Figure 1.
Here he can see that some curved sedimentary rocks have been cut vertically by a sheet of volcanic rock called a dyke.
