What does the age of a tree have to do with the age of the earth?But for the specimen to be useful in extending the tree-ring chronology, the absolute calendar age of its rings must be determined.The annual growth rings vary in thickness each year depending on environmental factors such as rainfall.Even the apparent absence of DNA differences is not 100 per cent certain, it seems, though probable.It appears that traditional tree-ring dating on any timber found growing at the site so far gives an age of no more than 4,000 years.A literal understanding of the biblical chronologies places the Flood no earlier than about 2,500 B. The presence of fossiliferous sediment under the BCPs rules out any of them being pre-Flood. Yet the Bristlecone Pine (hereafter BCP) long chronology, comprised of hundreds of live and dead trees, is over 8,000 years long.

Newspaper reports have claimed that what looks like hundreds of trees densely covering one hectare (2.5 acres), is all part of the one tree, since all these 'trees' appear to have identical DNA.Over the years, it is believed, 'snow has forced its branches to the ground, where they have taken root'.(, January 28, 1995, page 1.) It is hard to see how a tree could be older than the time since the biblical Flood, so if its published age of 'more than 10,500 years old' were correct, then this would present a serious challenge to Old Testament chronology.Generally, it is not possible to construct a complete sequence of tree rings back through the historical periods using only living trees.Chronologies derived from living trees must be extended.

We could add disease and excessive activity by pests to that list.
