Carbon dating live mollusk
The age they came back with was only a few thousand years old. And kept their theory that dinosaurs lived "millions of years ago" instead. They then use potassium argon, or other methods, and date the fossils again.
This date did not fit the preconceived notion that dinosaurs lived millions of years ago. They do this many times, using a different dating method each time.
Atheist bloggers who make sport of challenging creationists were calling this utter nonsense. In 1984, he published a paper in The American Association for the Advancement of Science’s prestigious journal, , which reported that a live snail from an artesian spring in Nevada was found by carbon dating to be 27,000 years old. What this means in simpler terms is that the shells of the snails were formed from existing ancient material from which most of the carbon 14 had been depleted.Many people are under the false impression that carbon dating proves that dinosaurs and other extinct animals lived millions of years ago.What many do not realize is that carbon dating is not used to date dinosaurs. Carbon dating is only accurate back a few thousand years.So if scientists believe that a creature lived millions of years ago, then they would need to date it another way. They assume dinosaurs lived millions of years ago (instead of thousands of years ago like the bible says).They ignore evidence that does not fit their preconceived notion.
