Re: Are you saying that researchers who have bored through old trees or into glaciers or into ancient lake beds, counted the rings and layers, and calibrated those annual markers with data derived from radiometric dating (which just happens to match up with the tree rings and glacier layers and lakebed varves -- go figure)))

Wow! Show me those 70K year old trees! How exciting. And the "ancient ice" drilling research in Antarctica only goes back a few thousand years, or so I had previously thought. Have they drilled into a 70K old glacier in the arctic that I haven't heard about?

What a job--counting 70K rings on that stump.

Show me a 2000 year old Bible, or better yet a 6000 year old original manuscript.

No one mentioned "70k year trees." Dendrochronology has been used to calibrate radiocarbon dating for items a few thousand years old or younger. Of course you knew that, but you were shooting for hyperbole, which is the hallmark of creationists who know they have nothing else. And, if you'd actually done ANY research on ice cores, you'd have learned they they go back more than three-quarters of a million years, and have also been used to calibrate radiometric dating.

But hey, I've learned to expect invincible ignorance from you.

Apparently:

"Two projects conducted from 1989 to 1993 collected parallel ice cores just 30 kilometers apart from the central part of the Greenland ice sheet. Each core is more than 3 kilometers deep and extends back 110,000 years."
