Why was the discovery of no rocks older than 2 billion years old on the ocean floor so important?

• This evidence proved that new seafloor features are constantly being added due to reversals of Earth's magnetic field.

• This evidence proved that new seafloor features are constantly being added due to seafloor spreading

• This evidence proved that the rocks on the seafloor were older than rocks on continents.
