The ruse attempted, will be to hold the fear, to create the fear, so all of the above does not change. This will be done via the 'et is evil and trying to kill us' story.
Which is IMPOSSIBLE (ET trying to kill us), as their technology would naturally be so far beyond what you know, that it would be meaningless to worry about them. If they wanted to end us, we'd be dead long ago.
Now, that's the mundane analysis. Then it gets into exactly WHAT is a 'human', anyway.
And you can't take what you know, the ideas and thoughts from the world around you, all the projected ancient fears..... and paste it onto any advanced beings. The reality is, all of that... simply can't stick.
They'd (advanced beings) be too far outside of our capacity to understand for any of our 'fears' to be relevant.
