It is possible to tell the number of years ago a particular rock or archeological site had been formed.

He would have answered that the Earth was ancient, that there had not been a Noachian flood, and that the species of life had not been fixed over the history of Earth.

In short, Genesis was an allegory and not literal history.

Relative dating does not provide actual numerical dates for the rocks.

Fossils are important for working out the relative ages of sedimentary rocks.

Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.

The method of reading the order is called stratigraphy (layers of rock are called strata).Radiometric dating and certain other approaches are used to provide absolute chronologies in terms of years before the present.The two approaches are often complementary, as when a sequence of occurrences in one context can be correlated with an absolute chronlogy elsewhere.For example, the presence of recycled bricks at an archaeological site indicates the sequence in which the structures were built.Similarly, in geology, if distinctive granitic pebbles can be found in the sediment beside a similar granitic body, it can be inferred that the granite, after cooling, had been uplifted and eroded and therefore was not injected into the adjacent rock sequence.These cosmogonies were part of the new emphasis of science in seeking rational explanations of the features of the world. This period was marked by a great deal of field geology rather than grand cosmogonies.
