Stan Romanek became one of the most famous and controversial figures in ufology during the 2000s, claiming to be the "most documented alien abductee in history." He gained widespread notoriety by presenting alleged physical evidence of his encounters, including a viral video of an alien peeking through his window, complex mathematical equations supposedly implanted in his mind, and mysterious body scars. His claims initially attracted a massive following and even inspired the 2016 documentary Extraordinary: The Stan Romanek Story.
