by Helen Fryman Question: What about radiocarbon dating? Response: I asked several people who know about this field. (1.) C14 dating is very accurate for wood used up to about 4,000 years ago.
This is only because it is well calibrated with objects of known age.
Some believe trees are known to be as old as 9,000 years. A lot of people doubt this claim for various good reasons I wont go into here.We believe all the dates over 5,000 years are really compressible into the next 2,000 years back to creation.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).Robert Whitelaw has done a very good job illustrating this theory using about 30,000 dates published in Radio Carbon over the last 40 years.One of the impressive points Whitewall makes is the conspicuous absence of dates between 4,500 and 5,000 years ago illustrating a great catastrophe killing off plant and animal life world wide (the flood of Noah)!I hope this helps your understanding of carbon dating.If you have any more questions about it don't hesitate to write.(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).The methodology is quite accurate, but dendrochronology supposedly shows that the C14 dates go off because of changes in the equilibrium over time, and that the older the dates the larger the error.
