Hi!
So I have something to consider: The first human who achieves faster than light travel doesn't return to Earth, but just keeps flying deeper into space!
They encounter all sorts of aliens who are just so confused as to why this gangly biped from a non-space-faring planet is there.
Some assume the worst and think it escaped from some sort of abduction, and are actively trying to tempt them into a cage to take back to Earth.
