For this hypothetical, let’s say it’s not aliens actually visiting earth. But let’s say JWST finds a planet maybe a few hundred light years away, and we can see lights and cities and maybe spaceships or stuff like that around it. So no contact, but 100% proof there’s intelligent life out there. How would humans (and different groups of humans, like conservative Christians) react to this?
conservative Christians would try to disparage and ban all discussion/investigation/proof, be embarrassing successful in these efforts and eventually resort to organized political violence to usher in a global omnicidal apocalypse that threatens our entire biosphere.
so basically what's already going on now without the aliens.
