Radiometric dating measures the decay of radioactive material in rock and organic material. By dating rock, many have dated the earth to 4.5 billion years old because the measurements of the decay consistently indicate 4.5 billion years. For the biblical Creationist, one would expect advanced decay rates because God created a mature universe just as the Genesis account presents. A mature creation would have a mature decay rate that is best set for the creation even if the universe is thousand of years old.
Assumptions in Dating
The atheistic worldview relies on naturalistic assumptions in chronological dating that exclude God creating an advanced and operating Creation.[1] The fundamental assumption of radiometric dating are naturalistic assumptions that exclude considering the Creator or the creation of a mature universe. As biblical scientists would expect, the Nuvvuagittuq Greenstone Belt appears as the oldest geological formation. This supra-crustal belt contains fossilized microscopic life indicating that life existed very early in the history of the earth.[1]
Secular scientists admit to presuming that rock samples (and organic samples) contain no parent elements in its formation. They use radiometric dating perceiving that igneous rock is the original rock. The flaw with secular science is that it is secular and excludes the Creator. How many isotopes existed within the original igneous rock when God created the universe? Imagine a clock counting years and currently at 4.5 billion years. How long has that clock been counting if the clock started counting anywhere between zero and 4 billion years? God would have created an advanced and operating universe with ideal levels of radiation and daughter isotopes within the original rock. The secularist would assume that daughter isotopes could only indicate radioactive decay. Most forms of radiometric dating use igneous rock. Potassium-Argon dating for volcanic rocks can include daughter isotopes argon-40 in relatively recent lava flows (Reproducibility of K-Ar Ages of Rocks and Minerals, Excess Argon in Volcanic Rock, [3], [4], [5]).
Subjective Dating
Radioisotope dating is subjective to personal bias allowing one to decide between a dating method like Carbon-14 for thousands of years and Potassium-Argon or Uranium-Lead dating for millions of years. For instance, secular scientists also assume that fossil fuels are millions of years old. However, some tested samples of fossil fuel have detectable amounts of Carbon-14 (14C) indicating thousands of years in age rather than millions (Chemical History of 14C in Deep Oil Fields, Carbon-14 Content of Fossil Carbon, [3], [4]). Either measuring 14C is an unreliable means of dating and, or the Earth is less than 60,000 years old.
Furthermore, the Earth’s environment has changed in climate and atmosphere offsetting assumptions for radioisotope dating. For 14C dating to be accurate then the atmosphere must constantly contain the same amount of 14C throughout the centuries. However, 14C is changing and is not constant in the atmosphere (14C Activity and Global Carbon Cycle Changes over the Past 50,000 Years, [2], Carbon Clock).
Conclusion
Secular scientists make assumptions in the use of radiometric dating and overlook the self-evident Creator. By excluding the Creator, they overlook the expectation of God creating the universe must include a balanced level of radioactive elements in igneous rock. God created the universe in a mature state. Radiometric dating that considers the Creator can consider that God created the earth some time after 4.5 billion years ago whether billions, millions, or thousands of years ago. Secular scientists exclude the Creator because of the naturalistic assumptions of uniformitarianism that they must borrow from theism. Uniformity is contrary to time-and-chance materialism. Radiometric dating is a moot point, unreliable for late-dating, and unreasonable for denying God.
God can create mature rocks, mature trees, set the speed of starlight, and form an adult man and woman while only days old. Radiometric dating cannot date the origin of the earth if God created a mature universe. The answer lies outside of radiometric dating and in the order of the universe. The universe is fine-tuned for life to observe the universe. Whatever begins must have a cause, and the universe began and must have a cause that transcends it. The complexity of the universe beyond human design and natural chaos indicates the most probable explanation that in the beginning God created the heavens and the earth.
