Why is human memory so unreliable?

Inspired by [this](https://www.reddit.com/r/AskReddit/comments/g2csg5/what_fact_is_ignored_generously/fnlesbi?utm_medium=android_app&utm_source=share) comment by u/squigs, I came here to ask you: Why we can’t remember details of things and, in most of the times, we make up things to fill the gaps on our memory.

Why does our brain do this?

Our memory evolved as a tool to help us survive, not as a method of storing information perfectly.

For survival, it is advantageous to remember the important things like what dangers were learned about, what new information was learned, and how to apply new skills (and any other important broad strokes) but not the exact series of events.

Over time, the irrelevant information gets pared away so that new, more relevant information can be stored.
