The Forerunners and Precursors each individually hold a technological, numerical, territorial, firepower, maneuverability, speed and tactical capability advantage over Star Wars. Death Star can blow up a Forerunner planet? Forerunner starships could blow up stars as a standard tactic. Star Forge to build an infinite supply of ships? That would qualify as a very inefficient factory to the Forerunners, who built out of light and adamantium. Starships powered by a miniature star? Forerunner technology is powered by destroying entire nascent universes and siphoning their energy. Use cloning and droid production facilities to create an endless supply of troops? Try hitting the Forerunner Warriors when they're busy tearing chunks of the planet you're standing on out from under you, or becoming immune to your weaponry. Amassing an invasion army? Nuke it from the edge of the star system with a tactical Halo pulse. There's nothing anyone from Star wars could do against the Forerunners, much less the Precursors, who can use their equivilent of gardening tools to crush planets into black holes, slice stars and systems to pieces, shut down any and all technology across galactic distances, warp space and time until the very sky itself is a hellish, fear-inducing nightmare, could build completely indestructible objects millions of miles long made of pure psychic thought, can shape and move galaxies across the universe, and either travel between universes or survive the death of one. also self-resurrect and be older than time.

Just stop. You're making yourself look dumb.

Still not answering the question, so you got nothing then. Force wins and halo gets force backhanded
