The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old.Astronomers and geologists have determined that the universe and Earth are billions of years old.What would happen if a dinosaur bone were carbon dated?- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.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.
As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.
Some of these rocks are sedimentary, and include minerals which are themselves as old as 4.1 to 4.2 billion years.
Rocks of this age are relatively rare, however rocks that are at least 3.5 billion years in age have been found on North America, Greenland, Australia, Africa, and Asia.
Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface.
The oldest rocks which have been found so far (on the Earth) date to about 3.8 to 3.9 billion years ago (by several radiometric dating methods).
