Yeah, but that's a little too anti-human, and plus if they were so good they wouldn't go around blowing us all up, they'd give us fusion power or something to solve our problems. xP
But our governments would basically take that fusion power and continue to fuck us and our planets up - you know how it works. Gov take power for military benefits...any country would do that. I'm thinking like this. This is an ancient race of alien - call them guardians if you'd like - who have been traveling space/time for who knows how long, doing right by planets and helping the underdogs (humans) out on their way. They give us basic techniques. Wireless electricity for the egyptians/mayans/aztecs, basic skills for crop building, and what have you. Their intention was to allow us to flourish, but with guidelines, spread the "help" they gave us throughout our world in order for us to thrive....but instead that help was demolished and turned to greed. While the alien race must stop at "billions" (lets just say there are billions of planets out there with alien races) to study and help/protect them.....they also have to come back and check on their projects. Maybe they checked on us throughout the years (ufo sightings) and we were "ok" but as of recently with constant war, constant poverty, constant greed of resources...they initiated a plan to take back what is theirs as our race no longer appreciates it...thus wanting to take back control and punish us for what we have become. They are after all the elite race in time/space.
I mean - considering what types of alien movies they have out there...............this idea really isn't that bad.
Well... yeah xD
But if they're so futuristic I imagine they can just fix everything, especially 4500 years later with new technology; I mean imagine us in 4500 years. In about 100 years we went from horse drawn carriages to flying to the moon, computers, internet, lights, the first planes, the first jet planes, the first space planes, the first phones, the first wireless phones, the first smart phones and so on. What's the next step? What's 4500 years going to be like when technology is speeding up exponentially?
They'd be so advanced they could just come in and fix everything, why kill us all? And why punish and kill billions of innocent people who had nothing to do with it, especially if it was a government at fault; at worst they'd punish the government. With fusion technology they could produce infinite food, clean water, whatever you want, provided we had enough fuel, which it's hydrogen so, we'd have an unlimited amount. All of that would help out with war as well, so, we'd probably see it doing all that. Why grow crops when we can just create them in a lab?
Also, why not leave some aliens here, or implement them in such a manner to force it to be used as they want?
I mean they'd have great technology n stuff.
I always wanted to make a show similar to Code Geass except with a lot more realism. All of it is like nanobots and aliens, and the mythology is more into how precusor alien technology goes to the hyper oppressive government which is how they're able to stay in power so long.
The nanobots give them "super powers" when it's really just alien technology, and they're too stupid to know how to use it. Until your protagonist finds a lot of it, of course. xP
