So just how many "millions of years" can soft tissue, blood cells etc last?

[Xavier]

3 simple questions for the evolutionists.

1. Can soft tissue survive millions of years? You know as well as we do - some evolutionists know even better than us students of creation science, as proven by the fact that most of them vigorously opposes Dr. Mary Schweitzer's discovery of soft tissue in "65 million year old" fossils for decades, before reluctantly conceding the reality - that the discovery of the same seriously calls into question the presumed millions of years arrived at by other methods. So, can it?

2. Do give us at least 3 distinct lines of evidence demonstrating to at least moral certainty that a stated fossil (take any mentioned in the excerpt below) is hundreds of millions of years old . Please prove that different methods of dating all give the same date, kindly mention the assumptions of (1) decay rate and (2) presumed original quantity etc made for radiometric dating, and give a brief estimate of the range of uncertainty (e.g. 100 million plus or minus 10 million evolutionary years etc)

3. What to do when dating methods seem to give contradictory results? Can the extreme likelihood that soft tissue cannot in fact survive millions of years be used to infer that these fossils are not millions of years old? Why or why not? Are we just to discount that a priori as a plausible way to arrive at the true age? Which method has precedence and for what reason?

Some documentation below from the Kolbe centre for creation. http://kolbecenter.org/question-of-time/

Carbon 14 is an isotope formed by the radioactive decay of carbon atoms, which is not supposed to be detectable in organic material older than about 50,000 to 60,000 years because of its short half life. However, it is often found in materials dated by other methods to be millions of years old, including petroleum, coal, wood, and bone, and has even been detected in diamonds otherwise dated at billions of years of age.[10],[11],[12]

Additionally, the surprising discovery of soft tissue in fossils presumed to be millions of years old brings radiometric dating into direct contradiction with currently observed decay rates of organic materials.  In 2005 and 2007, evolutionary scientist Mary Schweitzer reported on the discovery of what appeared to be blood cells in 65 million years old tyrannosaur bones.[13],[14] This presented a quandary for scientists, because organic material is not supposed to last that long based upon present decay rates.[15] When her work was called into question, Dr. Schweitzer obtained similar tissue in 80 million year old hadrosaur bones, went to extraordinary lengths to prevent contamination and perform rigorous tests on her samples, and defended her discovery in an article in Science that appears to have satisfied her detractors.[16] But nobody, including Dr Schweitzer, has called into question the high improbability of blood surviving 65-80 million years.

More ancient organic matter has been unearthed since Schweitzer's original discovery.  Examples include:

Exoskeleton remnants discovered in 417 million year old eurypterid and 310 million year old scorpion (February 2011)[17]
Dark colored, soft tissue melanocytes found in 120 million year old dinosaurs[18] (May 2010)
Preserved ink sac from 150 million year old squid[19] (August 2009)
Original shell preserved from 189-199 million year old lobster[20] (September 2010)
Organic molecules preserved in 66 million year old hadrosaur[21] (July 2009)
Preservation of scaly soft tissue in 36 million year old penguin[22] (September 2010)
Remains of 50 million year old insects found preserved in amber[23] (November 2010)
Blood and eye tissues, skin and cartilage preserved in two 80 million year old mosasaurs[24],[25] (March, October 2010) and one 70 million year-old mosasaur[26](May 2011)
Bone marrow found in 10 million year old frog[27] (July 2006)
Muscle tissue found in 18 million year old salamander[28] (November 2009)
Original feather material found in 150 million year old archaeopteryx[29] (May 2010)
In a study published in April 2011, researchers in Sweden subjected soft tissue from a presumed 70 million year old mosasaur to a battery of tests to determine if the material was original to the organism.[30] Not only did they confirm that the tissue was indeed original, but the fibrous tissue absorbed dye just like connective tissue from a modern bone.

They can last however long evolutionists need them to last. That's the beauty of "science" - one can always add an ad hoc hypothesis to a set of data that would otherwise conflict with a theory. The flaw in Popperianism is that falsification of a theory is in principle impossible and a theory is unlikely to be discarded when it forms an essential part of an ideology, never mind so much money, time and careers being staked upon it!
