She says this is ok so long as you take into account the correction factors from dendrochronology.(They conveniently forget to mention that the tree ring chronology was arranged by C14 dating.
Scientists have tried to extend confidence in the carbon dating method further back in time by calibrating the method using tree ring dating.
So when you hear of a date of 30,000 years for a carbon date we believe it to be early after creation and only about 7,000 years old.
If something carbon dates at 7,000 years we believe 5,000 is probably closer to reality (just before the flood).
(2.) I just listened to a series of lectures on archaeology put out by John Hopkins Univ.
The lecturer talked at length about how inaccurate C14 Dating is (as 'corrected' by dendrochronology).
