Answer:
The literal meaning of history is.
the study of past events, particularly in human affairs.
the whole series of past events connected with someone or something.
Now my answer.
History is the makeup of our society and it shapes the way we live today.
Think of all our customs and everything we do down to the food we eat, it's all traced down through history.
History is a tool we use to learn and make important decisions military-wise and in everyday life wise and without it, we literally would not know a single thing.
