Bigfoot.

The legend of Bigfoot begins in 1958, when journalist Andrew Genzoli published a letter from a reader of the paper he worked at. The letter detailed mysteriously large footprints that loggers in northern California had found. "Maybe we have a relative of the Abominable Snowman of the Himalayas," Genzoli wrote, according to History.com.

Ever since then, the country has been hooked on trying to spot this giant creature, particularly in the Pacific Northwest, where alleged sightings have been the most frequent. There have been dozens of movies, books, podcasts, and articles written about Bigfoot.
As Insider previously wrote, Bigfoot has been called a "ferocious beast who attacks loggers and hikers, or a gentle giant who wants to be left alone. "
