Here's why:
* Folklore: Ghost stories are deeply rooted in folklore and oral traditions from all over the world. These stories often serve as a way to explain the unknown, warn against danger, or reinforce social norms.
* Ancient Cultures: Evidence of ghost beliefs can be found in ancient cultures like Ancient Greece (with stories of the Underworld and the dead), Ancient Egypt (with beliefs about the afterlife and the spirits of the deceased), and many more.
* Evolution: Over time, these stories evolved and became more complex, incorporating elements of religion, superstition, and even psychology.
So, while there isn't a single inventor, it's more accurate to say that ghost stories are a product of collective human imagination, shaped by generations of storytelling and cultural beliefs.
