Is History A Science?

The question on whether history is a science is based on how accurately view history as a credible source for information which we can percieve as a fact with no with no or little doubt of  inaccuracy.
   Science on the other hand is viewed as fact. This means that it will be noted down as being 'true' until proven otherwise. This has become the norm because scientific experiments are done as they are looked into and can be proven because the viewers sense perception allows them to be convinced that this is fact.
   In the case of history, this is mostly based on speculation and intuition where the event that is being assessed, transpired prior to its importance in the historians eyes, and he as to look back and find 2nd hand accounts and artifacts that prove his theory.
