TruthExplorer: "As someone who questions everything, (...) They carbon date the rock and bingo, it's 230 million years old? Where on earth do they come out with these figures?"
Hi truthexplorer. It is good that you question everything, but you got to start by questioning your own assumptions. For instance nobody has ever carbon dated a rock because you can't use carbon dating on rocks.
For me, believing archeologists estimates in years based pn carbon dating would be like believing the overlapping generation teaching
You are right the historical record only goes back so far (and is largely constructed), but that's why scientists have tested carbon 14 dating against a great many external sources of verification representing very diverse chronological processes. Are you aware of that literature?
Here is a graph i made a few years back that shows the agreement between C14 dating and more than 10 external datasets offering more than 10 sources of independent confirmation of Carbon 14 dating for the past 10000 years.
