ELI5: In media why is light always associated with ''good'' and darkness always associated with ''evil''?

i'm talking about tv series, cartoons, games, and movies, where the bad guy prefers dark places and/or uses darkness magic, it is such a cliche but what is its origin? just to make the bad guys look intimidating and/or mysterious?

It's not just from new media, this has been a "cliche" since the dawn of time being used in almost all cultures in literature, storytelling, art, religion, etc.

As to why this is such a popular symbolism, the answer is quite simple. Humans are active during the day, from our own biology we know that the sun is good for us (it's warm, it helps us see, etc.) and the night is dangerous (cold, you cannot see, many predators are nocturnal, etc.).

It just mirrors our daily experience.
