Any written document, otherwise that would be an source and be a part of history.
By finding artifacts
Prehistory is that very long period of human existence where no written historical accounts were made.
they think about clues they got when they find artifact's from prehistory that how historians investigate the past.
We study that in a subject called Geology.
This is because history is the study of the written past, while prehistory is the study of the unwritten past. Archaeologists find their answers from material which is found in the ground, and anthropologists find their answers by trying to match the human behaviour of some societies with the evidence that the archaeologists found.
Historians study the past by studying the previous recorded events of the past activities. They use both the scientific and traditional methods to gather such information which they then use to compile their documentary evidence.
Scientists use a variety of tools and techniques to study prehistory, including archaeology, carbon dating, genetic analysis, and the examination of fossils. By analyzing these sources of evidence, scientists can reconstruct timelines, understand human behaviors, and piece together a more comprehensive picture of our ancient past.
they study the history of our world and the continents such as america
The study of prehistory reveals information about human evolution before the existence of written records.
Historians need archaeologists to provide physical evidence to support their theories and interpretations about past societies. Anthropologists help historians understand the cultural context of historical events by studying human societies, behaviors, and beliefs. Together, archaeologists and anthropologists provide a more comprehensive and nuanced understanding of the past.
