Well, they mixed in chimp DNA to get older ages (since we're related after all ). They didn't, other than complain about a heat problem.
There is one test, done by ev's on a mosasaur humerus which obtained 4.68% (of modern content) C14...equating to a date of 24,600 years.
This manuscript proposes a new approach for science's battle against the rising influence in America of pseudo-science and the Creationist movement. In recent years Creationism has grown into a force capable of challenging orthodox science in the arena of public opinion (Schmidt, 1996).
The framework of Creationist Bible-based earth history, focusing on Genesis and the Noachian flood, can be assembled into a single geologic time scale (Figure 1, enlarged by addition of many geologic facts, difficult for Creationists to explain. After federal courts struck down attempts to force teaching of creation "science" in the public schools, Creationists have taken a new approach.
Bede was one of the first to break away from the standard Septuagint date for the creation and in his work De Temporibus ("On Time") (completed in 703 AD) dated the creation to 18 March 3952 BC but was accused of heresy at the table of Bishop Wilfrid, because his chronology was contrary to accepted calculations of around 5500 BC.A 2017 Gallup creationism survey found that 38% of adults in the United States inclined to the view that "God created humans in their present form at one time within the last 10,000 years" when asked for their views on the origin and development of human beings, which Gallup noted was the lowest level in 35 years.The first major comprehensive draft of Genesis was composed by the Yahwist in the late 7th or the 6th century BC, during the Babylonian captivity, with later additions made by the priestly source in the post-exilic period.I'm very familiar with the creationist testing of dino bones for C 14.That is not relevant here, however, as you have not demonstrated it is a scientific method that dates the Earth at 6,000 years old. How did the old earthers solve the Mitochondrial DNA evidence that showed Eve = 6K years?Shai Cherry of Vanderbilt University notes that modern Jewish theologians have generally rejected such literal interpretations of the written text, and that even Jewish commentators who oppose some aspects of science generally accept scientific evidence that the Earth is much older.
