That means they don't really know how old their rocks actually are.

The key in relative dating is to find an ordered sequence.

In 1905, Ernest Rutherford figured out that we could use radiation to establish the ages of rocks.

He could be pretty confident that his super awesome dinosaur was about 175 million years old.

Stratigraphic and fossil succession are good tools for studying the relative dates of events in Earth's history, but they do not help with numerical dating.

In 1896, a French physicist named Henri Becquerel discovered radioactivity in an element called uranium.

He saw that it underwent radioactive decay, or emission of energetic particles to produce new elements.

Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.
