Go to an encyclopedia and look up fossils or paleontology.  You'll probably find an explanation of the process that science uses to establish the age of fossils and rocks.  As you read you will discover that certain index fossils provide clues to the age of the rock that contains them.  So far so good, but keep reading.  Later you will learn that rock layers are used to date the fossils contained in them.  A mad circle has been uncovered.  How can either tell the age of the other if either depends on the other to establish its own age?  This is circular reasoning.

Paleontologists assume that biologists have proven evolution to be true.  But biologists assume evolution to be true, so their dating schemes are based on an assumption that has never been proven.  We do well to be skeptical of an old earth for the same reason; the earth must be old since evolution is true and requires such a time frame, at least that is how some would have us believe.  This certainly is not science, even though it comes from the evolutionist old earth camp.  Circular reasoning is just one common tactic that has been used to establish credibility for a theory in distress - evolution and its requirement of an old earth.  Go to the next page to learn more about the tactics of this debate.  Some are more subtle than others but they are all designed to prop up a theory that lacks real evidence.  See for yourself.
