There is something of a fallacy here, sediments are dated by fossils and fossils are dated by sedimentary layer. It's a closed loop. All the fossil record tells us is that life has had long enough to evolve, but not how long that has taken.

I'm not arguing that the Earth isn't old, I'm just making a point.
