I'll chime in on the stuff I know.
Another example is coal. According to the geologic column, it takes several hundred million years for coal to form. Coal samples yield a radiocarbon age of only several thousand years.
C14 is not JUST produced in the atmosphere. It is also produced by normal radioactive decay of elements in the ground. There will be a low level of C14. Coal dates to the extreme limit of the method. It is like trying to measure an 18-wheeler on a home scale, they only go up to about 300 lbs. You are not suggesting that 18-wheelers weight 300 lbs just because we picked a stupid way to measure it do you?
Even today, when you hear someone saying that they have found a dinosaur fossil 100 million years old, it is not because of radiocarbon dating, but simply because the geologic column says that dinosaurs went extinct 65 million years ago. Radiocarbon dating on dinosaurs have yielded dates more than 10000 years.
Radiocarbon dating on fossils is simply stupid. There is no more carbon left in a fossil. The definition of a fossil is organic material that has been REPLACED by minerals in the surrounding rock. Most things that are fossilized are also at the extreme limit of the method. See the comment above about an 18-wheeler. People who radiocarbon date fossils are just trying produce erratic results KNOWING that the method will produce them because it just does not fit. This is complete and utter dishonesty by Creationists. See my signature.
If evolutionists are right in maintaining that life started a few billion years ago, 99% of fossils would yield a radiocarbon date of more than 10000 years. But according to radiocarbon databases, more than 90% of fossils have an age less than 10000 years. This is in spite of the fact that we have instruments that can measure ages up to 70000 bp.
Once again, you are going to get erratic results becuase it is just plain retarded to carbon date fossils. You are just measuring the carbon content of the rock. Radiocarbon dating rocks is futile and dishonest. The rest of the post is more of the same. When Creationists do any radioisotope dating, they usually do it to stuff they KNOW is outide the method or just plan invalid. See
Snelling's invalid use of radiocarbon.
Of course, biblical creationists are committed to belief in God's written Word, the Bible, which forbids bearing false witness; --AIG (lest they forget)
