In some cases these astronomical cycles in rock appear to have been laid down over some 25 million years (and radiometric dating puts the absolute age of the rock at some 200 million years).
For instance, measurable amounts of C-14 have been found in fossil material, such as coal (traditionally Carboniferous period c300 mya).
Radioactive parent (P) atoms decay to stable daughter (D) atoms e.g.
the carbon isotope C-14 decays to nitrogen-14 and the uranium isotope U-235 decays to the lead isotope Pb-207.
The earth precesses (wobbles like a spinning top) around the sun in a series of cycles.
These cycles affect sunlight and hence long-term can form layers in rock.
Some claim Genesis in particular, and the Bible in general looks mythical from this standpoint.
