I don't think there's any extra-terrestrial activity going on here on Earth, period. Maybe elsewhere in the Universe and probably not in our solar system either.
So quite unlikely, though possible if they take a multi generational approach.
given that the universe is so large there's not a number that can accurately measure its true size or age, you mean to tell me you think that humans are the only intelligent lifeforms to exist currently, have existed, or will exist?
Come on now.
I think that extraterrestrial UFO conspiracies are extra juicy because they also infer negative things about the US government.
