Perhaps you’ve not heard they did a blind test on rocks and strata from the 1980 Mt. Saint Helens eruption that was calibrated to be over a million years old using radio-isotope dating methods. The sedimentary layering mimics the evolution story of ‘millions’ of years.
Here are 51 thru 64 from my prior link that you apparently have not read...while uranium dating is not discussed in great detail, Ur is in much greater detail in the references listed - but only for those who read and think critically.
Don’t you see all of the evidence needs to agree for millions/billions to really be possible. The scientific method does not allow for ignoring so much contradictory data does it?! Even carbon dating is inconsistent b/c they often ASSUME uniformity rather than what effects burying all the plants and animals in a global flood would do to cause a massive spike in their calculations.
=== Radiometric dating and the age of the earth ===
51. Carbon-14 in coal suggests ages of thousands of years and clearly contradict ages of millions of years.
52. Carbon-14 in oil again suggests ages of thousands, not millions, of years.
53. Carbon-14 in fossil wood also indicates ages of thousands, not millions, of years.
54. Carbon-14 in diamonds suggests ages of thousands, not billions, of years. Note that attempts to explain away carbon-14 in diamonds, coal, etc., such as by neutrons from uranium decay converting nitrogen to C-14 do not work.
55. Incongruent radioisotope dates using the same technique argue against trusting the dating methods that give millions of years.
56. Incongruent radioisotope dates using different techniques argue against trusting the dating methods that give millions of years (or billions of years for the age of the earth).
57. Demonstrably non-radiogenic isochrons of radioactive and non-radioactive elements undermine the assumptions behind isochron dating that gives billions of years. False isochrons are common.
58. Different faces of the same zircon crystal and different zircons from the same rock giving different ages undermine all dates obtained from zircons.
59. Evidence of a period of rapid radioactive decay in the recent past (lead and helium concentrations and diffusion rates in zircons) point to a young earth explanation.
60. The amount of helium, a product of alpha-decay of radioactive elements, retained in zircons in granite is consistent with an age of 6,000±2000 years, not the supposed billions of years. See: Humphreys, D.R., Young helium diffusion age of zircons supports accelerated nuclear decay, in Vardiman, Snelling, and Chaffin (eds.), Radioisotopes and the Age of the Earth: Results of a Young Earth Creationist Research Initiative, Institute for Creation Research and Creation Research Society, 848 pp., 2005
61. Lead in zircons from deep drill cores vs. shallow ones. They are similar, but there should be less in the deep ones due to the higher heat causing higher diffusion rates over the usual long ages supposed. If the ages are thousands of years, there would not be expected to be much difference, which is the case (Gentry, R., et al., Differential lead retention in zircons: Implications for nuclear waste containment, Science 216(4543):296298, 1982; DOI: 10.1126/science.216.4543.296).
62. Pleochroic halos produced in granite by concentrated specks of short half-life elements such as polonium suggest a period of rapid nuclear decay of the long half-life parent isotopes during the formation of the rocks and rapid formation of the rocks, both of which speak against the usual ideas of geological deep time and a vast age of the earth. See, Radiohalos: Startling evidence of catastrophic geologic processes, Creation 28(2):4650, 2006.
63. Squashed pleochroic halos (radiohalos) formed from decay of polonium, a very short half-life element, in coalified wood from several geological eras suggest rapid formation of all the layers about the same time, in the same process, consistent with the biblical young earth model rather than the millions of years claimed for these events.
64. Australias Burning Mountain speaks against radiometric dating and the millions of years belief system (according to radiometric dating of the lava intrusion that set the coal alight, the coal in the burning mountain has been burning for ~40 million years, but clearly this is not feasible).
Or consider polystrate fossils from:
Center for Scientific Creation - In the Beginning: Compelling Evidence for Creation and the Flood
Polystrate Fossil. Fossils crossing two or more sedimentary layers (strata) are called poly- (many) strate (strata) fossils. Consider how quickly any fossil must be buried. Had burial been slow, the tree tops would have decayed. Obviously, the trees could not have grown up through the strata without sunlight and air. The only alternative is rapid burial. Some polystrate trees are upside down, which could occur in a large flood. Soon after Mount St. Helens erupted in 1980, scientists saw trees being buried in a similar way in the lake-bottom sediments of Spirit Lake. Polystrate tree trunks are found worldwide.
You're asserting that you can prove the Earth is 10,000 years old by excluding any evidence that it isn't. Not exactly rocket surgery, there.
The key word is "blind".
Accuracy requires a full understanding of the context of the material being tested.
