The idiom "ancient history" is used to describe something that happened a long time ago and is no longer relevant or important to the current situation. It is often used to dismiss or downplay past events or experiences that are no longer significant.
For example, if someone brings up a mistake you made a long time ago, you might say "That's ancient history, let's focus on the present." This means that the mistake is not important anymore and should not be dwelled upon.
Another example could be if someone is talking about a past relationship that ended a long time ago, you might say "That's ancient history, you should move on and focus on the future." This means that the past relationship is no longer relevant and it's time to move on.
In short, "ancient history" is a way to describe something that happened a long time ago and is no longer important or relevant to the current situation.
