The rock layers are a very good indicator of age, even with out the use of carbon dating.

If the world were created as the Bible states then why are there no fossils of ancient man, dinosaurs, mammoths, and literally thousands of other animals, why are these not found on the same layer of rock.

Because if they did all live together then there would be all of these fossils lying on the same layer all over the world. Yet they are not.

The only way this would be possible is if the animals, plants, etc. buried themselves either before or after there death.

I believe scientists have done more than enough to prove that these creatures existed at different points in the history of earth.
