Soft tissue discoveries in fossils does not negate radiometric dating methods.
Fossils supposedly over 65 million years should not be scientifically expected to have non-mineralized organic cells
such as hemoglobin, chitin, silk, DNA, melanin, etc. as are known to exist. There is speculation those were known about decades ago, but lacking explanations, the knowledge has remained buried until recently. Chemically it would be impossible for such cellular material not to have been mineralized. The very nature of passage of the ions through rock strata makes preservation of organics impossible, the very ions and changess of them being the basis of radiometric dating.
Radiometric dating is based on many unobserved assumptions/concepts favored by evolutionists. The ways the methods are calibrated are contaminated by their circular reasoning. Regardless, having well preserved organic cells within mineralized fossil remains ought to increasingly place evolution in it's proper place (mysticism).
That subject alone points to T rex and others having lived a few thousand years ago. But I agree that to date there is apparently no science data pinpointing the age of earth to 6,000 years. Edgar Rice Burroughs could have stretched it out to maybe a million years with convincing prose with or without any science backing. The evidence examined without evolution bias is pointing to a very young earth, less than 10,000 years.
During my last geology course field trip we examined a very large quarry. As expected our guide explained the hundreds of rock strata represented a huge slice of geologic time, showing most of the "geologic column". He refused to try explaining how all that sediment could remain plastic enough to tolerate the extreme folding (180 degrees vertical) without leaving at least microscopic fracturing. That was a 21 year old college senior who had done his homework. The only plausible answer is all of that sediment was laid down suddenly, day by day, then heaved up to present position, then hardened. Currently such deposits can harden into rock in a matter of decades. The guide's answer to that was we know the ages of deposition by the fossils in each layer, and radiometric dating, all of which is calibrated by methods fashioned by evolutionists. Besides, if an exam contains questions about that quarry, be advised to supply the official answers, as it is these days too. So for the interim we all "agreed" with evolution. It's the game they play, on their own field, and their ball.
Many evolutionists are doubtless anxiously awaiting retirement before the head of evolution is finally blown off publicly by real science. It already has been mortally wounded, but academia is ruled by secular scientists who insist on making science fiction into "science" without the benefit of real science. Follow the money.
