The pre-historic period, which encompasses the time before written records, lasted for tens of thousands of years, rather than being measured in centuries. It is generally divided into three main phases: the Stone Age, Bronze Age, and Iron Age, with the Stone Age itself lasting from approximately 2.5 million years ago until around 3,000 BCE. This extensive timeline makes it difficult to quantify the pre-historic period in terms of centuries.
In Philippine history, the pre-Hispanic period refers to the period before the arrival of the Spaniards. This is approximately before the 16th century.
The Cambrian period occurred approximately 541 million years ago, marking the beginning of the Paleozoic Era. The Pre-Cambrian is a broad division of time before the Cambrian period, encompassing about 4 billion years of Earth's history, including the formation of the planet and the evolution of life prior to complex multicellular organisms.
The pre-Columbian era refers to the time period in the Americas before the arrival of Christopher Columbus in 1492. It spans thousands of years and includes various civilizations such as the Maya, Aztec, and Inca.
