Alright HN, we all know that this is likely untrue, from a rational angle, and this thread is full of reasons why, but play this mental exercise with me for a minute: What if its true ? What repercussions would having alien technology have on civilization? Would this fundamentally change beliefs? Influence religion? EDIT: someone pointed out to make this more stimulating we need constrains, assuming the following is…
From a political perspective, it is risky because all our current rules are based on a now-obsolete ontology, nothing needs preservation, we are just animals again, all is material. It creates a power vacuum that some people will rush into.
The rationale for that would be, if you don't have to fear the aliens, and we're tiny specs in the universe, why should you fear other men? We are now one species and if you can't get on board with that, there are no moral consequences to shortening your time here, since as we are not the top of the pyramid, we can no longer be held morally responsible to each other - there is only this new power. If it doesn't control us, nothing does, etc.
I think the religious view would be that they must also know God, and the only way you can trust another species enough to relate to it is either it accepts your dominion, or recognizes some similar principles of divine authority. Someone who has a personal relationship with God is perfectly equipped to relate to other beings as best a human can, whereas without that, they'd have to worry about you stealing stuff.
