daily bible devotions for dating couples - Relative dating of fossils and rocks
Current understanding of the history of life is probably close to the truth because it is based on repeated and careful testing and consideration of data.
The rejection of the validity of fossils and of dating by religious fundamentalists creates a problem for them: Fossil sequences were recognized and established in their broad outlines long before Charles Darwin had even thought of evolution.
This principle has in the meanwhile been established to be true for all sediments worldwide, and is the basis of worldwide correlation of sedimentary rock units and one of the underpinnings of the theory of evolution. In location A we have rock layers that successively have different types and combinations (assemblages) of fossils.
If in location B we find the same fossil assemblage (Assemblage 2) in a rock unit, we may assume that they are of essentially the same age as in location A.
Correlating two separated outcrops means establishing that they share certain characteristics indicative of contemporary formation.
