Potassium Argon dating:
Potassium Argon dating is based on many of the same assumptions and gives wild dates shown below. Since so many wrong dates are found, how would we know which dates are "correct?"
For years the KBS tuff, named for Kay Behrensmeyer, was dated using Potassium Argon (K-Ar) at 212-230 Million years. See Nature, April 18, 197, p. 226. Then skull #KNM-ER 1470 was found (in 1972) under the KBS tuff by Richard Leakey. It looks like modern humans but was dated at 2.9 million years old. Since a 2.9 million year old skull cannot logically be under a lava flow 212 million years old many immediately saw the dilemma. If the skull had not been found no one would have suspected the 212 million year dates as being wrong. Later, 10 different samples were taken from the KBS tuff and were dated as being .52- 2.64 Million years old. (way down from 212 million. Even the new "dates" show a 500% error!)

Basalt from Mt. Etna, Sicily (122 BC) gave K-AR age of 250,000 years old.

Lava from the 1801 Hawaiian volcano eruption gave a K-Ar date of 1.6 Million years old.

In addition to the above assumptions, dating methods are all subject to the geologic column date to verify their accuracy. If a date obtained by radiometric dating does not match the assumed age from the geologic column the radiometric date will be rejected.
The so-called geologic column was developed in the early 1800's over a century before there were any radiometric dating methods. "Apart from very 'modern' examples, which are really archaeology, I can think of no cases of radioactive decay being used to date fossils."Ager, Derek V., "Fossil Frustrations," New Scientist, vol. 100 (November 10, 1983), p. 425. Laboratories will not carbon date dinosaur bones (even frozen ones which could easily be carbon dated) because dinosaurs are supposed to have lived 70 million years ago according to the fictitious geologic column. An object's supposed place on the geologic column determines the method used to date it. There are about 7 or 8 radioactive elements that are used today to try to date objects. Each one has a different half-life and a different range of ages it is supposed to be used for. No dating method cited by evolutionists is unbiased.
A few examples of wild dates by radiometric dating:
Shells from living snails were carbon dated as being 27,000 years old. Science vol. 224, 1984, pp. 58-61
Living mollusk shells were dated up to 2300 years old. Science vol. 141, 1963, pp.634-637
A freshly killed seal was carbon dated as having died 1300 years ago! Antarctic Journal vol. 6, Sept-Oct. 1971, p.211
"One part of the Vollosovitch mammoth carbon dated at 29,500 years and another part at 44,000.

"One part of Dima [a baby frozen mammoth] was 40,000, another part was 26,000 and the "wood immediately around the carcass" was 9-10,000.

"The lower leg of the Fairbanks Creek mammoth had a radiocarbon age of 15,380 RCY, while its skin and flesh were 21,300 RCY.
--In the Beginning Walt Brown p. 124
The two Colorado Creek mammoths had radiocarbon ages of 22,850 670 and 16,150 230 years respectively."

"A geologist at the Berkeley Geochronology Center, [Carl] Swisher uses the most advanced techniques to date human fossils. Last spring he was re-evaluating Homo erectus skulls found in Java in the 1930s by testing the sediment found with them. A hominid species assumed to be an ancestor of Homo sapiens, erectus was thought to have vanished some 250,000 years ago. But even though he used two different dating methods, Swisher kept making the same startling find: the bones were 53,000 years old at most and possibly no more than 27,000 years a stretch of time contemporaneous with modern humans."

"Structure, metamorphism, sedimentary reworking, and other complications have to be considered. Radiometric dating would not have been feasible if the geologic column had not been erected first."
