Over the years, archaeologists have compiled their findings into large databases containing information about the types of artifacts that correspond with difference civilizations, and the types of soil in which they usually found. In typology, a researcher studies the material of an artifact, its form, and its most likely purpose.Due to technological necessity, more complex artifacts are newer than simpler artifacts, so often an artifact can be dated simply by looking the materials and process used to make it.The human race has existed for at least one hundred thousand years, and perhaps even longer.However, writing was only invented in 5000 BCE, and even then, few people were literate and archival methods were very poor.Archaeologists sometimes use experimental methods to help them understand how people may have performed tasks in the past.

This is a systematic examination of the land looking for sites.

New techniques may allow them to learn from data and artifacts that have been curated for many years.

Similarly, archaeologists often revisit old data armed with increased knowledge about the past and a new set of questions.

Organisms take in carbon-14 naturally while they are alive, but when they die, they stop absorbing it.

Carbon-14 has a half-life of 5,000 years, so it slowly decays and its frequency declines as the organic material is buried.

Typically, archaeologists search for sites on foot, although aerial surveys are used to reveal sites that are invisible at close range and where the terrain makes walking difficult.
