A closer examination (not possible from this picture) would reveal contact metamorphism where the intruding igneouos rock "cooked" the pre-existing sedimentary layers.Formation of an Unconformity Layers are formed according to superposition.Many Christians accept this and interpret the Genesis account in less scientifically literal ways.However, some Christians suggest that the geologic dating techniques are unreliable, that they are wrongly interpreted, or that they are confusing at best.
Example: the layer that marks the extinction of dinosaurs has characteristics of an asteroid impact.Many are also unaware that Bible-believing Christians are among those actively involved in radiometric dating.This paper describes in relatively simple terms how a number of the dating techniques work, how accurately the half-lives of the radioactive elements and the rock dates themselves are known, and how dates are checked with one another.Life begins as single cells about 3.5 Billion Years ago. Most of the life that has evolved (99.9%) has become extinct.Ex.: Cro-Magnon Man is extinct because they evolved into modern Homo-sapiens.
