In every single case, the Scooby Doo gang discover a human is behind the mystery, not ghosts or mummies or whatever. Yet they start each new case believing the villain is a supernatural being. Every time. Not once do they say “maybe it’s an old man like last time”
@JoParkerBear isn't that wonderful, that with no matter how many reality checks, we can still believe in ghosts & fairies & magic& some thing other-worldly.
It's the ultimate faith. It's what keeps us young.
