Using uranium 238 in radiometric dating
The various confounding factors that can adversely affect the accuracy of carbon-14 dating methods are evident in many of the other radioisotope dating methods.Although the half-life of some of them are more consistent with the evolutionary worldview of millions to billions of years, the assumptions used in radiometric dating put the results of all radiometric dating methods in doubt. Although the half-life of carbon-14 makes it unreliable for dating fossils over about 50,000 years old, there are other isotopes scientists use to date older artifacts.This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.Carbon-14 dating has been used successfully on the Dead Sea Scrolls, Minoan ruins and tombs of the pharaohs among other things. The half-life of carbon-14 is approximately 5,730 years. dinosaurs the evolution alleges lived millions of years ago.Levels of carbon-14 become difficult to measure and compare after about 50,000 years (between 8 and 9 half lives; where 1% of the original carbon-14 would remain undecayed).The question should be whether or not carbon-14 can be used to date any artifacts at all? There are a few categories of artifacts that can be dated using carbon-14; however, they cannot be more 50,000 years old.Once our geologist had the “index fossil” that was found approximately in the same layer as the newly discovered fossil, he would then see where in the geologic column it came from and presto, he now had a date for his newly discovered fossil.He would simply go to a chart that listed the geologic column by ‘ages’ and find the place where the index fossil appears, and thereby the geologists could tell the paleontologist how old his fossil was.
Also, many fossils are contaminated with carbon from the environment during collection or preservation procedures.
Any radiometric dates that show a supposedly “old” rock to be young are rejected “Few people realize that the index fossil dating system, despite its poor assumptions and many problems, is actually the primary dating tool for geologic time. In other words, radiometric dating methods are actually fit into the geological column, which was set up by [index] fossil dating over 100 years ago.”(Michael Oard, meteorologist and creationist scientist, 1984) All radiometric dating methods use this basic principle to extrapolate the age of artifacts being tested.
These long time periods are computed by measuring the ratio of daughter to parent substance in a rock, and inferring an age based on this ratio.
the geological column and approximate ages of all the fossil-bearing strata were all worked out long before anyone ever heard or thought about radioactive dating …
There are so many sources of possible error or misinterpretation in radiometric dating that most such dates are discarded and never used at all, notably whenever they disagree with the previously agreed-on [index fossil] dates.” (Dr Henry Morris, creationist scientist and hydraulicist, Ph D in hydrology, geology and mathematics, Fellow of the American Association for the Advancement of Science and the American Society of Civil Engineers, former Professor of Hydraulic Engineering at Virginia Polytechnic Institute, 1974) Michael Oard, Ph. is a meteorologist and creationist scientist who writes, And when it comes to dating any individual rock today, the resulting “date” is forced to conform to predetermined evolutionist “dates” based on these imaginary 19th century index-fossil “dates”.
