They allow us to "know" (calculate - estimate [it depends]) what conditions were like at a known time in the past.
A scientist who studies the history of life on Earth is called a paleontologist. They examine fossils and other traces of ancient life to understand how organisms have evolved over time.
A geologist
A seismologist is a scientist who specifically studies and monitors vibrations in the Earth, including earthquakes and other seismic events. They use specialized equipment to detect and analyze these vibrations to better understand the Earth's structure and behavior.
A geologist studies the Earth's physical structure, substances, history, and processes. They analyze rocks, minerals, and fossils to understand the Earth's composition and formation. Geologists also study natural phenomena like earthquakes and volcanoes.
a weather man of course helloA meteorologist
Scientist drill into ice and remove ice cores for study. Scientist analynze air trapped in the ice to learn how the atmosphere has changed. Scientists can develop an accurate history of overall weather patterns over time.
So they can be smart

No scientist found the Earth.
James Hutton discovered the uniformitarianism theory, which states that the earth has changed and is still changing overtime, but very slowly.
Same as everybody else - kiss his butt goodbye. But he/she would understand why they were dying.
