I explained that there was in the clearest terms possible with examples (such as history)
Actually SBF history is examined using primary sources. A primary source is anything that is extant from the period whether it be an official document, a personal letter, household accounts, a building or even a painting. These are examined and a theory of what happened in that period is developed which does follow the scientific method.
Of course experimentation cannot be carried out to confirm the theory but as new evidence come to light, as new primary sources are found the theory is adjusted. Secondary sources also add adjustments. These are historical accounts written about the period and may have been created not long after the events.
