Who were these precursor aliens I mentioned last night? Where did they go and why are the stargates still working? The interstellar travel doubletalk is just an excuse to go somewhere and let aliens come here, but what if the stargates are sentient beings with a desire to ‘Serve Man’ or any sapient lifeform? Why? Again, what happened to their creators? What if their stargates and technology turned against them because they were terrible people, flipping the ‘Skynet’ thing around? We could turn ‘Footfall’ upside down while we’re at it as well.

Forget the FTL and interstellar and go with two alien factions coming to the solar system to involve us in their troubles. Of course, their technology could make it possible, perhaps comparatively easy, to survive and remediate climate change.
