Marvel's Eternals spans several thousand years of human history on Earth, showing all ten of the heroes throughout various historical eras all over the world. While the film goes into some detail about how certain members of the Eternals influenced different human myths and legends during their time on Earth, it doesn't go into great detail on how they were able to go unnoticed for the past few hundred years. However, a newly released deleted scene sheds a bit more light on one of the biggest contributing factors that helped them remain inconspicuous for so long.

The scene, entitled "Small Talk," shows Dane Whitman meeting up with Sprite at the Natural History Museum where both he and Sersi work. Sprite goes into great detail about events in her past with Sersi and the other Eternals, acknowledging Thena's powerful influence in the creation of the goddess Athena myth and correcting Dane's claim that a Deviant skull on display is that of a saber-toothed tiger. She goes on to describe how her powers of illusion are responsible for the very foundation for modern society, as humanity's belief in concepts like gods, nations and money are all just illusions, which she taught to the world many millennia ago.

During this Eternals scene, Dane treats Sprite exactly as most adults would treat a pre-teen spinning such stories, indulging her seemingly outlandish claims without actually believing any of them. This becomes increasingly clear when Sprite tells him Sersi's ex-boyfriend can fly and Dane goes on to reassure her that his romantic relationship with Sersi will not take her away from Sprite. While his behavior does come off as a bit condescending, it also holds the secret to the Eternals' ability to hide in plain sight since they went their separate ways: no one will believe their stories about their past.

While this initially seems like a stretch given all of the fantastical events that have taken place in the Marvel Cinematic Universe, humans have proven time and again to be skeptical when confronted with truths that don't fit into their understanding of the world. Jane Foster is very reticent to believe Thor's claims of Asgard and Mjolnir when she first meets him in Thor, only opening herself up to the possibility that he may be telling the truth after spending more time with him and doing some additional research of her own.

One of the more recent examples of such skepticism occurs during The Falcon and the Winter Soldier's premiere episode, "New World Order." Bucky Barnes, while on a date with a waitress named Leah, tells her that he is 106 when she asks him his age. She writes it off as an attempt at humor even though he is telling her the truth, given that Bucky does not look anywhere close to his actual age.

If Eternals is any indication, it seems that even with all of the various alien invasions, government conspiracies and cross-dimensional exploits that have unfolded under the public eye, everyday people in the MCU are just as skeptical of new information that contradicts their established worldview as they are in the real world. After more than ten years of battles in New York and villainous robots trying to destroy the planet, ten immortal beings protecting the Earth for 7,000 years in secret is apparently still too far-fetched for folks in this universe to believe in at first glance.
