History is?

Author’s note: short journal prompt that our AP world teacher wanted us to write, last year. The question is the title, and this is my response, or most of it. He wanted me to include certain things, so I did at the end, but I took them off, because it would make much more sense without that sentence.
History is a study of the past that a variety of people sought to interpret, and thus, resulting in many different points of view of the same accounts. Individuals look at it and analyze the evolutions in time so that we know how it effects the present. This shows us a reflection of what has happened. Some are to be repeated, and some are to be prohibited. We know of such knowledge, because they have been discovered, some of these are in writing and some in other various forms.
