So your justification for a sweeping generalization of technology
is a scene from a science-fiction movie -- emphasis on the "fiction" part -- based on a fictional novel?
I suppose, then, that we can make the same claims about the real world:
-- "sugar-coated" vampires are living in the Pacific Northwest (aka "Twlight")
-- fairy-tale monsters are actually human-looking species living among us, who can only be seen for their true selves if they decide to reveal it to us, or unless you happen to be descended from a group of knights from the 4th Crusade (aka "Grimm")...or were actually deposited in the Northeast USA through a catastrophic magic curse that removed nearly all of their memories (aka "Once Upon a Time")
-- the 'gods' worshipped by the ancient Greek, Roman & Egyptian cultures are not only alive & well, but are both interacting with & tied into the social, political, & cultural events of our modern world (see "Percy Jackson & The Olympians", "Heroes of Olympus", and "The Kane Chronicles")
-- the Seelie & Unseelie courts of the Sidhe/Faerie are also interacting with our modern-day culture, thanks to a treaty they signed with President Thomas Jefferson almost 200 years ago (see "Meredith Gentry" series)
No matter how it's researched, no matter how "logical" it may sound (or even how much it may match up with our personal worldviews, let alone meeting our "wish fulfillment" needs), fiction is just that: fiction. It's not factual (at least not 100%), which means it doesn't meet evidenciary requirements for supporting a scientific "theory" or "law". So while the scene of pseudo-apelike humanoids interacting with a giant, black rectangular solid was a nifty visual (whether seen in the movie or in our imagination from reading the novel), it doesn't mean it actually happened without providing documentable proof (i.e. archaelogical evidence).
Especially since, as we well know, films & novels can be modified (as in the infamous "Han shot first" debate)...
