I have received radiocarbon dates >11,000 years of age. (Didn't I mention this to you before, or was that somebody else?)
Not to mention varves, cresoote bush rings, ice cores. Of course these all match exactly, the fat years and the lean years, summer and winter, hot and cold, wet and dry, major and minor, Guelphs and Ghibellines, but I digress.

FYI, this request from GD arose in response to my original point about the young earth and flood geology being falsified and abandoned by pre-Darwinian, creationist geologists.
I cited this historical fact as a refutation of GD's claim that rejection of YEC had a "metaphysical" and antievolutionary basis. IOW YEC was debunked by scientists who were ALL antievolutionists, and most of whom were also strong Christians (e.g. Sedgewick, Buckland, Coneybear, Hugh Miller, etc) so it couldn't have been, and historically wasn't, based on or in defense of evolution.
So, anyway, strictly speaking, the facts falsifying YEC should be from among those that convinced scientists prior to 1859, which of course was before radiometric dating.
That said, GD has probably been too busy moving his goal posts to follow the discussion that closely anyway.
