The Force

I have one question: Who discoverde the Force (The Light
side of the force and dark side of the force
???

As far as I've ever heard, that hasn't been published. But I could be wrong.

I think the light side of the force first started

and then some people rebelled

and became dark side of force

The original force users used a blend of the two but leaned toward the light side of the force. But then some became power hungry and began to fully use the dark side.

According to Star Wars lore, the dark side of the Force was discovered first, with ancient alien species like the Rakata being the first known users of its power, harnessing it to conquer large parts of the galaxy; therefore, the "dark side" was discovered before the "light side" in the Star Wars universe.
