If you're expecting to be able to pin something down to say, nine o'clock on a Tuesday morning, you might run into problems.
The point is that a record, in fact several different types of records, including tree-rings, varves, ice-cores, and other methods, all point back systematically to a virtually unending time-span.
Those lake-bed sediments get compressed into sedimentary rock, which stacks up higher and higher until it isn't even at the bottom anymore! The Earth, in upheaval, moves things around, and what would have been inaccessible at the bottom of an ocean is now freely observable at the top of a mountain.
Of course, this jumbling tends to make the process somewhat akin to a jigsaw puzzle, but we like puzzles, don't we?
In any case, even a tattered and worn bit of gospel is a balm to the soul and a refreshment to the spirit.

Not without a lot of fudging up to about 6000 years- beyond that it gets into a lot more fudging and throwing out dates that don’t fit the a priori belief- I’ve all sorts of links showing the problems with these methods if ya like?
Ice Cores
Varves
At best- the two methods above are only accurate to about 11,000 years due to numerous conditions and environmental uncertainties
Pollens
Corals
