I read, close to California in the 70's there was this slab on the side of a mountain showing, in great detail layer of crusts which was evidence of things through time. There was an earthquake that caused this layer formation to thrust up more exposing a tree. This tree was embedded in several layers at once. Obviously the tree didn't exist over billions of years, it'd been trapped in some lava and sediment in one event. There have also been records of TRex prints, a smilodan and a man's footprints in one river bed. All three existing at the same point in time, paralleled? Probably not, but that's just the point, there's these methods that don't prove anything to me honestly.
