I. Pre-historic man did not leave behind any written records. Why do you think that is? How did historians find out about how early man lived?
Answers
Explanation:
The scope of history
Historians currently think that anatomically modern humans have been around for between 200,000 and 300,000 of the planet’s 4.5 billion years. And even though 200,000 years is less than one 20,000th of the history of the planet, it is still a very long time!
For context, 200,000 years would represent at least 6,000 generations of your ancestors (your grandparents are only 2 generations from you). 200,000 years is also nearly 1,000 times as long as the United States has been a country. It is 100 times as distant in the past as the time of Jesus and the Roman Empire. It's also 40 times as distant in the past as the earliest written records we have found.
Think about the scope of what must have happened during that time: adventures, sorrows, environmental change, and the rise and fall of civilizations. As historians, we have the privilege of exploring this vast expanse of human experience.
Answer:
But we still have many tools. Archaeologists can excavate ancient structures and burial sites and begin to infer how the people lived from fossils (like human remains) and artifacts (human-made items). ... Age can also be determined by identifying the age of the layer of rock that the artifacts are buried in.
