So a time-line of the world constructed on biblical data would have man almost at the beginning, not the end.
If we took the same 15-inch (39 cm) time-line as does time-line.
Here is an easy-to understand analogy for your students: relative age dating is like saying that your grandfather is older than you.
Absolute age dating is like saying you are 15 years old and your grandfather is 77 years old.
presents what it claims is evidence for vast time spans.
This is graphically illustrated in a chart on pages 36–37: man’s existence is in such a tiny segment at the end of a 5-billion-year time-line that it has to be diagrammatically magnified twice to show up.

We know that we can relatively date layers of rock by knowing that the layers on bottom are older than the layers on top.First, Sedimentary rocks are formed when solid materials carried by wind and water accumulate in layers and then are compressed by overlying deposits.Sedimentary rocks sometimes contain fossils formed from the parts of organisms deposited along with other solid materials.To determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This rule is common sense, but it serves as a powerful reference point.Geologists draw on it and other basic principles ( to determine the relative ages of rocks or features such as faults.So, let's imagine for a second that you have a 3-layered cake. So, by definition, the oldest layer of cake would be chocolate, as it was put there first. Now all of a sudden the big tower of cookies running through the middle of your cake is the youngest feature, as the other three layers in order for it to be there.
