The 18th-century geologist James Hutton acknowledged that geologic processes require long timescales, an idea central to what we mean by the term deep time. The objective of geochronology—relationship rocks and fossils—is to weave collectively the dates we get hold of to tell the extraordinary story of Earth’s deep time. Radioisotopic relationship is a key tool for learning the timing of each Earth’s and life’s history. Which isotope is acceptable for dating rocks that are billions of years old? Due to its long half-life, U-235 is the best isotope for radioactive relationship, notably of older fossils 
and rocks. Amino acid courting is a dating technique[5][6][7][8][9] used to estimate the age of a specimen in paleobiology, archaeology, forensic science, taphonomy, sedimentary geology and other fields.

What strategies does relative courting use?
“No fossil is buried with its birth certificates,” wrote the renowned science editor Henry Gee in his 2000 treatise, In Search of Deep Time. While true, fossils are buried with plenty of clues that permit us to reconstruct their history. An array of absolute courting strategies has made it possible to determine the timescale of Earth’s historical past, including the age and origin of life, the timing of mass extinctions and the report of human evolution. But, no, according to the doctrine of created antiquity, the universe was created with mild from those stars and galaxies already on its way to Earth.
