Since so many wrong dates are found, how would we know which dates are "correct? Then skull #KNM-ER 1470 was found (in 1972) under the KBS tuff by Richard Leakey. 1999 Lava from the 1801 Hawaiian volcano eruption gave a K-Ar date of 1.6 Million years old. B., 1969 40Ar/36Ar analysis of historic lava flows. There are about 7 or 8 radioactive elements that are used today to try to date objects. A hominid species assumed to be an ancestor of Homo sapiens, erectus was thought to have vanished some 250,000 years ago. "Structure, metamorphism, sedimentary reworking, and other complications have to be considered.
They do not know that the amount of carbon-14 in the atmosphere is constant. In addition to the above assumptions, dating methods are all subject to the geologic column date to verify their accuracy.
Present testing shows the amount of C-14 in the atmosphere has been increasing since it was first measured in the 1950's. Etna, Sicily (AD 1972) gave K-AR age of 350,000 years old. If a date obtained by radiometric dating does not match the assumed age from the geologic column the radiometric date will be rejected. 30 "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. 124 The two Colorado Creek mammoths had radiocarbon ages of 22,850 670 and 16,150 230 years respectively." --In the Beginning Walt Brown p.
This is why most people say carbon dating is only good for objects less than 40,000 years old.
Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years.
This would prove the earth is not yet 30,000 years old!
This also means that plants and animals that lived in the past had less C-14 in them than do plants and animals today.They are, obviously, assuming the amount of carbon-14 in the atmosphere has always been constant, and its rate of decay has always been constant.Neither of these assumptions is provable or reasonable.Whenever the worldview of evolution is questioned, this topic always comes up.Let me first explain how carbon dating works and then show you the assumptions it is based on.This may be tied in to the declining strength of the magnetic field. Kilauea Iki, Hawaii (AD 1959) gave K-AR age of 8,500,000 years old. The so-called geologic column was developed in the early 1800's over a century before there were any radiometric dating methods. 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. 124 "A geologist at the Berkeley Geochronology Center, [Carl] Swisher uses the most advanced techniques to date human fossils.Tags: Adult Dating, affair dating, sex dating
