inexpungeable

[Justin Bieber]

Inexpungible means that an event cannot be erased or undone, no matter how much you try. It is a concept that describes something so important or significant, it cannot be altered in any way. An example of an inexpungible event could be a major natural disaster, such as an earthquake or hurricane. Another example could be a significant political change, such as the election of a new leader or the passing of an important piece of legislation. In either case, the event cannot be undone or altered in any way, and it is seen as an essential part of history.
