Relative and numerical dating techniques
The fossils which are buried deep inside the earth are more ancient.
While in the absolute dating, isotopes of carbon are used for dating fossils.
Pragmatism verus Materialism American Journal of Science Jan 1976 page 54-55 Fossils date rocks not vice[versa and that's that.
Absolute dating is based on radioactive decay half lives.
Instead, it is about how geologists and archaeologists use different techniques to figure out how old rocks and other artifacts are.
You may be asking yourself, 'Why do we even care about dating rocks?
Scientific American Oct 1980 156-168 The rocks on the surface of the southern Appalachians are older than the sedimentary layers under them.
The timeline established by the theory of Darwinian evolution ultimately determines the age of fossils found in any given strata.
The results are often determined by the estimates of the presumed age of the strata based on relative ages.
The age determined by relative dating is based on the rules of super imposition and the presumed age of strata based on fossils.
The deeper strata is presumed to be older than strata above.
The strata with the simpler fossils is presumed to older than strata with more complex fossils regardless of which is above the other.
