How could a super intelligent person make such mistake in the first place?

A person employed as a line leader sets up an innocent employee for a dismissal by framing him for something he didn't even do, all because the person who DID report him to management told him I was the one who reported him.   I call him super intelligent for being able to pull off such thing to get me fired from one of my previous jobs after an idiot told him I was the one who reported him when I didn't.

This super intelligent person had also kept me UNEMPLOYED for most of 2020 by impersonating me on several job search engines with a damaging resume and a bad referee (his friend)
