Eventually, presumably after decades or psychological priming using occasional UFOs to reduce the chock, aliens come to earth to be the masters of humankind.
They are not like the aliens of ”independence day”. They are very intelligent and moral beings, giving us a lot of good stuff like the cure of cancer, longevity, the end of wars, starvation and most of crime etc.
They allow us a lot of personal freedom to travel, to raise a family, to make cinemas, to have religious activities etc but kind of restrict us regarding weapons, certain forms of science and some other things deemed to risky for them, us and others.
They are most benevolent to us, and even a bit god-like like we are like gods to our dogs. Or maybe (more accurate) like good parents towards 5-8-year old kids.
Like parents, those aliens would not be able to always handle things perfectly, if a group of humans got really destructive, they might have to use
some force or even violence, but not very much, thay have ways of stopping us and our bodies in ways that are not bloody or physiologically destructive in other ways.
They would be far more advanced than us, and in many ways not interfering too much with us. In many ways, they would keep to themselves, but would have interaction and communication with us too.
Why they'd come here? They feel they have a moral obligation to do so. They are convinced of being something like a white, shining city at the mountain top. They have observed the immense suffering, here and in some other worlds, and consider it better to intervene than not to intervene. They are aware of the risk of a negative psychological and cultural impact during maybe a hundred years, but are certain that problems due to that will disappear eventually and the total outcome would be a very positive one.
In fact, like good parents, they really are interested in us, in our history and philosophy, and they'd sometimes say that they too have a lot to learn from us.
In general, we would be able to live a better life than before, albeit with certain restrictions, but not at all severe restrictions, not at all like in the Soviet Union or North Korea.
They would be a bit like angels. very good beings, sometimes harsh when necessary, but so would angels be too.
So, would this alien-goverened utopia be a good thing or a bad thing?
I suppose we are divided on this.
I imagine a movie where this division cuts a family in two. The wife and the children are very happy with the new order, while the husband feel like freedom and pride is lost and allies with freedom-fighters …
If something like this would ever happen, I think humans would be very suspicious, even paranoid, and I guess I would be that too, even if I am the kind of person who would choose being governed by good aliens if they would be able to reduce the suffering on this planet. If I was certain that the aliens really were good, I would choose that, but in reality (since there wouldn't be any certainty) I would be very suspicious and fearful, waiting for the them to show their true colors...
