What is meant by deep time?

Deep time refers to the vast geological time scale that encompasses the Earth's history, extending over billions of years. It highlights the immense duration of natural processes, such as the formation of rocks, the evolution of life, and the shifting of continents. This concept helps scientists understand the slow changes that shape the planet and emphasizes the insignificance of human timescales in comparison to Earth's history. Deep time is fundamental to fields like geology, Paleontology, and evolutionary Biology.
