In the geological column , scientists have learned that rocks are stacked in layers. The oldest fossils are located in the deepest layers, a vertical timeline.

It is called Superposition.
The basement is a term sometimes used, and Cratonis another used in a continental context.The Principle of Superposition has it that in a given formation, the top layers are the youngest, and the deeper layers the oldest.

You would know because the youngest rock layer is always on the top, and the oldest is always at the bottom of the canyon.
The bottom layer of rock in a geologic sequence is usually called the basement layer.
You would know because the youngest rock layer is always on the top, and the oldest is always at the bottom of the canyon.
Superposition is the theory that the rock layer that is on top is the youngest and the layer of rock on the bottom is the oldest.

In a normal sequence (ie one that has not been tectonically deformed) the oldest layer is the lowest layer - so the one at the base of the sequence is the oldest. This is called the "law of superposition".
