Or is this good evidence that it is not that old??
“He acknowledges that certain conditions may slow the rate of degradation, “but not by a lot.”19 “Since proteins decay in an orderly fashion,” he considers it very unlikely that any condition “could arrest protein degradation for tens of millions of years.”20 In other words, Dr. Collins knows proteins are far from immortal. Thus, he faces the conundrum of his evolutionist position: protein cannot last millions of years in a buried fossil, but he is unwilling to consider the possibility that the age of these fossils is not millions of years…
…If the persistence of proteins in dinosaur fossils is difficult to explain, then the retention of intact sheets of tissue should be considered even more astonishing…The presumption that these sheets of tissue survived some 65+ million years of exposure to a host of potential environmental encroachments (e.g., ground radiation, microbial attack, and groundwater infiltration) stretches the bounds of biological preservation beyond any reasonable form of reality. It even stretches the bounds of imagination. It certainly stretches the limits of scientific credibility.”
