The rock walls were slippery and steep at points, and some people came in their dress shoes straight from the conference that brought them together. Let me see that. A brightly painted sign in the state park explained that million years ago these ancient creatures lived at the bottom of a warm, shallow sea during the Ordovician period. But none of these geologists believed it. As young-earth creationists, they think the earth is about 8, years old, give or take a few thousand years. Creationist ideas about geology tend to appeal to overly zealous amateurs, but this was a gathering of elites, with an impressive wall of diplomas among them Harvard, U. They had spent years studying the geologic timetable, but they remained nevertheless deeply committed to a different version of history. John Whitmore, a geologist from nearby Cedarville University who organized the field trip, stood in the middle of the fossil bed and summarized it for his son.

alleged unreliable radiometric age dating methods, largely come from were alleged in the RATE project organized by Answers in. Genesis.
Today, though, a friend of mine shared this youtube video from AiG about radiometric dating, and why it is supposedly unreliable for determining the age of rocks. Now, I am not a scientist, and most scientific discussion makes my eyes glaze over. My brain is wired for literature, poetry, and Biblical Studies. As I watched this short video, though, a few thoughts popped into my head that I just have to share.
First, take minutes and watch for yourself. Up to that mark, I was somewhat surprised: AiG gave a straightforward explanation regarding radiometric dating and half-life.
Geologist Ralph Harvey and historian Mott Greene explain the principles of radiometric dating and its application in determining the age of Earth. As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate. Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4. Segment from A Science Odyssey: “Origins. View in: QuickTime RealPlayer. Radiometric Dating: Geologists have calculated the age of Earth at 4.
Radiometric dating is largely done on rock that has formed from solidified lava. Such a scenario does not answer all of the questions or solve all of the problems that radiometric dating poses for those who believe the Genesis account of.
The RationalMedia Foundation board of trustees election is completed and the results are posted. Thank you for your interest and participation! Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have decayed. Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.
The time that it takes for half of a sample to decay is known as the half life of the isotope. Some isotopes have half lives longer than the present age of the universe , but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances. Various elements are used for dating different time periods; ones with relatively short half-lives like carbon or 14 C are useful for dating once-living objects since they include atmospheric carbon from when they were alive from about ten to fifty thousand years old.
See Carbon dating. Longer-lived isotopes provide dating information for much older times. The key is to measure an isotope that has had time to decay a measurable amount, but not so much as to only leave a trace remaining.
Answers in Genesis’ Deceptive Video on Radiometric Dating
The following comprises a series of essays written in response to a discussion held on the Message Board of this web site. The discussion, between a young creationist, Rob, and several other regular contributors, eventually came to the issue of radio isotope dating. Rob mentioned that Steve Austin’s Grand Canyon dating experiment cast doubt on the viability of absolute dating systems.
Also, the Genesis flood would have greatly upset the carbon balance. There are various other radiometric dating methods used today to give ages of millions all valid methods for the determination would give the same answer (within the.
The Institute for Creation Research ICR is a Creationist apologetics institute in Dallas , Texas that specializes in media promotion of pseudoscientific creation science and interpretation of the Genesis creation narrative as a historical event. Its work in the field of creation science has been rejected by mainstream science , but has been significant in shaping creationist thought in the United States by introducing creation science through fundamentalist churches and religious schools, and by engaging in public debates against supporters of evolution.
However, the Segraveses and Morris disagreed on the focus of the center, with the Segraveses favoring political and promotional activities, whilst Morris favored educational and scientific efforts. This led to the breakup of the center in , with the Segraveses taking control of the center and severing ties with the university, with Morris reorganising the remaining staff into the Institute for Creation Research.
The ICR defined its work in terms of three ministries: research, writing and speaking. Historian of science Ronald L. Numbers states that “[d]espite its name, the institute for years conducted little research outside the confines of its modest library” and cites founding member Duane Gish as “explain[ing] apologetically in , [that] the staff devoted much of its research effort to scouring the scientific literature for references favorable to creationism.
Science vs. Fiction
Let’s move down the article to “Bad Dates. Does that mean the earth is young It means the geologist has to do the best he can with the tools available to date the objects. I’m not going to try to defend these bad date answers. I cahow without the original articles. The creation genesis author is correct in calling this the “dating game.
Flaws in Dating? Roland Watts. Matt’s style is to post a link from a creationist web site, usually Answers in Genesis, which contains the usual bunkum that has been refuted many times then to refuse to acknowledge any rebuttals. Below is a critical look at one of Matt’s typical posts. In this one Matt airs the old creationist claim that the dating system is flawed. On March 10 you posted a link under the heading “Flaws in Dating“.
The link ended at an AiG site with an article, Flaws in dating the earth as ancient by Mr. Alexander Williams, B. Hons , Th. His credentials are impressive and his interests appear to be in science, statistics and creation issues. The specific article written by Mr Williams was brief, a web version of an article he posted in Creation Ex Nihilo 18 1 The thesis of the article follows the usual YEC complaints of conventional absolute dating systems.
Mainstream scientists make claims about the age of a certain rock unit. These claims are shown to be based on misunderstanding or misrepresentation when a creationist examines the relevant article.

NASA’s Genesis spacecraft spent more than two years collecting samples of the solar wind. The spacecraft then brought the sample cannister back to Earth where it parachuted to the ground. Despite a hard landing in the Utah desert, the Genesis samples were recovered. Genesis, the fifth Discovery-class spacecraft, was designed to collect samples of the solar wind and then bring them to Earth. The collection device, fixed inside the sample return capsule, was made of a stack of four circular metallic trays, one that would be continuously exposed, and the other three deployed depending on particular solar wind characteristics.
After insertion into a low parking orbit around Earth, the third stage fired exactly an hour after launch, at UT Aug.
When Nye pointed out that radiometric dating places the Earth’s age at more than $million project, Ham’s company Answers in Genesis.
The chronological figures related to genealogies in Scripture add up to approximately 6, years since the creation of described in Genesis. Many creationists consider these figures to be relatively complete, and thus the Earth is considered to be about 6, to perhaps as much as 10, years old. Biblical scholars do not agree on whether the Bible indicates that the planet Earth was created at the beginning of creation week or if it was already present as a lifeless, wet and dark planet here prior to creation week.
The Bible does not give an age for the Earth, nor is any theological point drawn from the age of the Earth, so it may not be as important as some of the other issues. Most scientists believe the Earth is about 4. This figure is based on radiometric dating. Some creationists have attempted to reconcile this figure with the creation in Genesis by proposing that the rocky, lifeless planet was created long ago perhaps 4. Other creationists hold that the planet itself was created during creation week, perhaps early in the first day of creation.
In this case, the entire planet would be about 6, to 10, years old. The minerals of the earth often contain atoms that are unstable and decay into a different kind of atom. Such unstable atoms are said to be radioactive.
