The Historical Event

“An event cannot enter history unless it’s been established as an fact.”

To begin with, I will move back to the often asked question, what is a fact? At what point does an assumption or a story establish itself as a fact? What/ Who is it determined by? Does the historian because of his power and tag the ultimate decision maker?
Now, when you look at an event, did it not happen because it has not been noticed and hence established as a fact and cannot be recorded in the history? Since no event in history can occur twice (or so I believe) under and within the same exact conditions, the only way it can be established as a fact is by recollections. Recollections the event and the people involved in it. These recollections can be oral, pictorial, literary etc. Are the facts based on these evidences to validate an event occurrence?
In Indian mythology, its story telling and word of mouth passed on from generations to generations. There are a very few scientific and numerical ‘facts’ which can confirm these events. So do the people stop believing it as their history? No, it stays true to them even though it doesn’t fully conform to the factual norms. In this aspect, the history is built up more due on the basis of traditions and beliefs.Hence I think, an event does not need to be fully established as a fact, in order to be remembered as a part of history.
