That’s pretty far-fetched BroJoeK - ice cores don not prove anything close to millions of years. You speak like one who has only lightly researched one side of the creation evolution debate.
Have you not read? Here are the first 11 indicators that not all natural clocks agree ~ and the majority differ vastly from the few evolution relies upon, but none are precise and accurate since we can neither prove starting conditions nor uniformity. From creation.com/age-of-the-earth...
=== Biological evidence for a young age of the earth ===
1. DNA in “ancient” fossils. DNA extracted from bacteria that are supposed to be 425 million years old brings into question that age, because DNA could not last more than thousands of years.
2. Lazarus bacteria—bacteria revived from salt inclusions supposedly 250 million years old, suggest the salt is not millions of years old. See also Salty saga.
3. The decay in the human genome due to multiple slightly deleterious mutations each generation is consistent with an origin several thousand years ago. Sanford, J., Genetic entropy and the mystery of the genome, Ivan Press, 2005; see review of the book and the interview with the author in Creation 30(4):45–47,September 2008. This has been confirmed by realistic modelling of population genetics, which shows that genomes are young, in the order of thousands of years. See Sanford, J., Baumgardner, J., Brewer, W., Gibson, P. and Remine, W., Mendel’s Accountant: A biologically realistic forward-time population genetics program, SCPE 8(2):147–165, 2007.
4. The data for “mitochondrial Eve” are consistent with a common origin of all humans several thousand years ago.
5. Very limited variation in the DNA sequence on the human Y-chromosome around the world is consistent with a recent origin of mankind, thousands not millions of years.
6. Many fossil bones “dated” at many millions of years old are hardly mineralized, if at all. This contradicts the widely believed old age of the earth. See, for example, Dinosaur bones just how old are they really?
7. Dinosaur blood cells, blood vessels, proteins (hemoglobin, osteocalcin, collagen) are not consistent with their supposed age, but make more sense if the remains are young.
8. Lack of 50:50 racemization of amino acids in fossils “dated” at millions of years old, whereas complete racemization would occur in thousands of years.
9. Living fossils—jellyfish, graptolites, coelacanth, stromatolites, Wollemi pine and hundreds more. That many hundreds of species could remain so unchanged, for even up to billions of years in the case of stromatolites, speaks against the millions and billions of years being real.
10. Discontinuous fossil sequences. E.g. Coelacanth, Wollemi pine and various “index” fossils, which are present in supposedly ancient strata, missing in strata representing many millions of years since, but still living today. Such discontinuities speak against the interpretation of the rock formations as vast geological ages—how could Coelacanths have avoided being fossilized for 65 million years, for example? See The “Lazarus effect”: rodent “resurrection”!
11. The ages of the world’s oldest living organisms, trees, are consistent with an age of the earth of thousands of years.

101 Evidences for a Young Age of the Earth...And the Universe
http://creation.com/age-of-the-earth
Conspicuously absent is Uranium. Even the RATE project could not reconcile the evidence of radiometric decay of Uranium with a young Earth. If the Earth is 10,000 years old, there should be samples of Uranium ore that only exhibit 10,000 years of decay. Where are they?
"Lightly researched" is a relative term -- I've seen most, if not all, of your points posted on Free Republic in previous threads, and I've posted answers to a good many of them.
BrandtMichaels: "That’s pretty far-fetched BroJoeK - ice cores don not prove anything close to millions of years."
Greenland ice cores have been counted back to 62,000 years.
Antarctic ice has been dated back 720,000 years.
BrandtMichaels: "1. DNA in “ancient” fossils. DNA extracted from bacteria that are supposed to be 425 million years old brings into question that age, because DNA could not last more than thousands of years."
At least two issues here: first, whether that DNA came from later contamination and second, whether some natural preservative such as anaerobic salt extended the otherwise much shorter survival of in-tact DNA code.
Neither issue challenges the well established age of Earth and its many rock strata.
BrandtMichaels: "2. Lazarus bacteria—bacteria revived from salt inclusions supposedly 250 million years old, suggest the salt is not millions of years old.
See also Salty saga."
Again, the first issue is potential contamination, since many life-forms survive and thrive in conditions impossible for most others.
And again the second issue is whether under certain conditions some bacteria can survive indefinitely in "suspended animation"?
And again, neither issue challenges the well established age of Earth and its many rock strata.
BrandtMichaels: "The decay in the human genome due to multiple slightly deleterious mutations each generation is consistent with an origin several thousand years ago."
Evolution consists of two main features: 1) descent with modifications and 2) natural selection.
"Descent with modifications" is driven largely by random mutations which happen in every generation of every species.
Most of these mutations have no effect on either the appearance or functions of an organism, since they occur in regions sometimes referred to as "junk DNA".
And once an organism is perfectly adapted to its environment, then every mutation which has some effect will be negative, and natural selection will prevent that mutation from passing onto future generations.
When an organism's environment changes, then some mutations will be beneficial and the population can begin to evolve again.
Humans, like every other species, experience mutations in every generation, and until recently were subject to the same natural selection as all other life.
In the future, human natural selection may be replaced by scientific modifications to correct DNA "errors".
BrandtMichaels: "4. The data for “mitochondrial Eve” are consistent with a common origin of all humans several thousand years ago."
Sure, if by "several" you mean about 200 thousand years ago.
BrandtMichaels: "5. Very limited variation in the DNA sequence on the human Y-chromosome around the world is consistent with a recent origin of mankind, thousands not millions of years."
More recent studies have increased the date of "Y-chromosomal Adam" from around 60,000 to 140,000 years ago.
BrandtMichaels: "6. Many fossil bones “dated” at many millions of years old are hardly mineralized, if at all.
This contradicts the widely believed old age of the earth.
See, for example, Dinosaur bones just how old are they really?"
As with previous examples you cited, the first issue is potential contamination by more recent organisms.
And again the second issue is, what were the conditions of preservation?
But a third point needs to be made, namely that these examples are not, as you claimed, "many", but rather extremely rare.
That suggests something very special about them, and points back to the conditions of 99.99% of fossils ever found, which conform to our expectations.
So, unless somebody finds the remains of Fred Flintstone cooking Brontosaur burgers on his grill, these less-than-fully explained exceptions are unlikely to overturn our ideas about pre-history. ;-)
BrandtMichaels: "7. Dinosaur blood cells, blood vessels, proteins (hemoglobin, osteocalcin, collagen) are not consistent with their supposed age, but make more sense if the remains are young."
Same responses as above.
BrandtMichaels: "8. Lack of 50:50 racemization of amino acids in fossils “dated” at millions of years old, whereas complete racemization would occur in thousands of years."
Same responses as above -- very rare examples where neither contamination nor special conditions of preservation have been ruled out, and therefore no conclusions about a "young earth" can be drawn.
BrandtMichaels: "9. Living fossils—jellyfish, graptolites, coelacanth, stromatolites, Wollemi pine and hundreds more.
That many hundreds of species could remain so unchanged, for even up to billions of years in the case of stromatolites, speaks against the millions and billions of years being real."
In fact, these examples confirm the basic ideas of evolution -- 1) descent with modifications and 2) natural selection.
Once an organism has perfectly adapted to its environment, natural selection will weed out any and all genetic mutations which reduce its ability to survive, and so certain species can remain little changed for tens, even hundreds of millions of years.
BrandtMichaels: "10. Discontinuous fossil sequences. E.g. Coelacanth, Wollemi pine and various “index” fossils, which are present in supposedly ancient strata, missing in strata representing many millions of years since, but still living today.
Such discontinuities speak against the interpretation of the rock formations as vast geological ages—how could Coelacanths have avoided being fossilized for 65 million years, for example?
See The “Lazarus effect”: rodent “resurrection”!"
Even you should recognize that as an argument from ignorance.
Because we haven't found certain fossils doesn't imply they are not there to be found, eventually.
Further, even you must understand that fossilization is a special and rare occurrence even under the best of conditions, and absolutely cannot happen otherwise.
In the long-term scheme of things, whole continents float around the globe, crashing into each other, bouncing away, great oceans open up and close, ice ages come and go, all the while conditions favorable to a certain species disappear over here, and arise over there.
Certain conditions will leave a nice fossil record, others leave none -- and tens of millions of years might separate those favorable conditions.
BrandtMichaels: "11. The ages of the world’s oldest living organisms, trees, are consistent with an age of the earth of thousands of years."
DNAs of various species of trees, just like any other species, can be compared and contrasted, and dates calculated for their most recent common ancestors.
These dates correspond to what fossil records also reveal.
BrandtMichaels: "Read more please but don’t ever forget historical ‘science’ is hysterical science ~ you can conjur almost anything since you can never repeat natural history using the scientific method."
The fossil record is not "conjured", nor is DNA analysis, nor are the many radiometric dating techniques, nor are our understandings of geological processes, which lead us to find oil, coal, iron, copper, gold, diamonds, etc., nor are scientific techniques for dating ages of stars, galaxies and the Universe.
All of that is firmly based in science, and none is challenged by theologically driven "doubting Thomases."
