It is a pity that bristlecone pines only go back 5-6000 years (as if that isn't long enough for a tree to live). That age in itself would be grist for the creationists mill, since they can argue that there are no trees older than that because the Earth wasn't created.
So, what about ice cores from Antarctica? One cannot dispute the annual layers in them, surely. How far do they go back - long enough to dispel 6000 years as the age of Earth?

Well very true, other examples. Stand at the bottom of the grand canyon and look up! Count the layers, think how long it took to lay down all those sediments. The white cliffs of Dover are made of the fossil remains of trillions of tiny sea shells. The chalk is hundreds of yards thick! I can think of dozens of other examples.
