Actually it was the movement that turned into chemistry as we know today.
Scientists believe that oxygen accumulated in Earth's atmosphere due to the activities of primitive photosynthetic organisms like cyanobacteria, which released oxygen as a byproduct of photosynthesis. Over time, this oxygen built up in the atmosphere through processes like the Great Oxygenation Event, ultimately leading to the oxygen-rich atmosphere we have today.

Scottish geologist James Hutton is credited with proposing the principle of uniformitarianism. He argued that the geological processes we see today have been shaping the Earth for millions of years, and that these processes can be used to explain Earth's past.

Uniformitarianism
It is important for scientists to classify both living and extinct organisms so that historians can know how the earth was millions of years ago and today. It is more important today so that scientists can help people preserve the earth.
No, the mountains we see today are not ancient tree stumps. They are formed through geological processes like tectonic plate movements and erosion over millions of years.

Today, the Earth's atmosphere is composed of about 21% oxygen by volume. This level has been relatively stable over time due to the balance of oxygen production by photosynthesis and consumption by respiration and other processes.
Uniformitarianism is the theory that the same geological processes we see happening today have been shaping the Earth's surface over millions of years. This idea, popularized by geologist Charles Lyell in the 19th century, suggests that the present is the key to the past when studying Earth's history. By examining current processes, scientists can better understand how landscapes, rock formations, and fossils were formed in the past.
