Foul. You know I can't do that. Prove to me that they are different.

Agreed. The Law of Superposition is fairly straightforward. However,
the rate and means of deposition are not evident and we can't rewind the
tape to see how they were deposited. In the case of coal seams, as I've
said before, the observations don't match the uniformatarian model of a
swamp deposit.
