talking about ghost and bigfoot

The belief in ghosts as souls of the departed is closely tied to the concept of animism, an ancient belief that attributed souls to everything in nature.[14] As the 19th-century anthropologist George Frazer explained in his classic work, The Golden Bough (1890), souls were seen as the 'creature within' which animated the body.[ Although the human soul was sometimes symbolically or literally depicted in ancient cultures as a bird or other animal, it was widely held that the soul was an exact reproduction of the body in every feature, even down to the clothing worn by the person. This is depicted in artwork from various ancient cultures, including such works as the ancient Egyptian Book of the Dead (ca. 1550 BCE), which shows deceased people in the afterlife appearing much as they did before death, including the style of dress.
