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.Dinosaurs supposedly died out 65 million years ago. Carbon-14 dating was recently performed on dinosaur fossils,1 and the results were presented at the Western Geophysics Meeting in Singapore, August 2012, a gathering of approximately two thousand scientists.1 The carbon-14 dating involved precautions against contamination.
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.The discovery of radioactivity late in the 19th century enabled scientists to develop techniques for accurately determining the ages of fossils, rocks, and events in Earth's history in the distant past.For example, through isotopic dating we've learned that Cambrian fossils are about 540-500 million years old, that the oldest known fossils are found in rocks that are about 3.8 billion years old, and that planet Earth is about 4.6 billion years old.The half-lives of several radioactive isotopes are known and are used often to figure out the age of newly found fossils.Different isotopes have different half-lives and sometimes more than one present isotope can be used to get an even more specific age of a fossil.
