Two-thirds in U.S. say government knows more than it's saying on UFOs
One-third thinks some UFOs are actual sightings of alien spacecraft
Residents of the West show highest belief

WASHINGTON, D.C. -- As an internet campaign called "Storm Area 51" has nearly two million people pledging to break into a highly secure military base later this month in the hopes of uncovering possible secrets about UFOs, a recent Gallup poll finds two-thirds of Americans believe the government knows more about the subject than it has conveyed.

For decades, UFO enthusiasts have claimed the government is warehousing crashed UFOs, and possibly aliens, at Area 51, part of an Air Force base in southern Nevada. In other UFO news, the Navy recently issued new guidance for personnel to report "unexplained aerial phenomena" after a spate of unusual sightings by Navy pilots.

The 68% today who believe the government is withholding information about UFOs is comparable to the 71% found in 1996. Both times, the results were similar among all main demographic groups, including by age, education and party identification.

However, it appears that only about half the number who think the government is hiding something about UFOs think it is covering up information about alien space landings, specifically. This conclusion is based on the finding that far fewer people give credence to UFO sightings or have witnessed them, personally, than think the government knows more than it's telling.

33% of U.S. adults believe that some UFO sightings over the years have in fact been alien spacecraft visiting Earth from other planets or galaxies.
The majority, 60%, are skeptical, saying that all UFO sightings can be explained by human activity or natural phenomenon, while another 7% are unsure.
16% of Americans say they have personally witnessed something they thought was a UFO while the vast majority (84%) have not.

Even as most Americans are skeptical that aliens have visited Earth, the majority (56%) believe that those who spot UFOs are seeing something real, not just imagining it. This is up from 47% in 1996, possibly reflecting public awareness of military testing and the proliferation of drones which people may think can be mistaken for UFOs.

Separate from possible space landings on Earth, about half of Americans, 49% think that people somewhat like ourselves exist elsewhere in the universe. Even more, 75%, believe that some form of life exists on other planets.

Western U.S. Leads Nation in Believing UFOs Are Alien Spacecraft

UFO believers are found in all demographic and political segments of society, but are particularly likely to be residents of the West. That is the home of Area 51, as well as nearby Roswell, New Mexico -- where a crash of some kind in 1947 sparked the Area 51 conspiracy theories that persist to this day.

Forty percent of residents of the West believe some UFOs can be attributed to alien visitors. This compares with 32% of residents in the East and South and 27% in the Midwest.
Westerners are also a bit more likely than those in other regions to say they have personally seen a UFO: 20% in the West vs. 12% in the East and 15%-16% elsewhere.

Additionally, the new poll finds significant differences in UFO sightings by education and income, with lower socio-economic Americans being more likely than their counterparts to report belief.

Notably, Americans identifying as Protestant and Catholic are similar to the national average in believing UFOs are real. However, Americans with no religious affiliation are more likely to put stock in UFOs, with 40% saying some have been alien visitors.

Americans' Key Views of UFOs

We have a question about Unidentified Flying Objects, also known as UFOs. Which comes closer to your view -- some UFOs have been alien spacecraft visiting Earth from other planets or galaxies, or all UFO sightings can be explained by human activity on Earth or natural phenomenon? Have you, yourself, ever seen anything you thought was a UFO?

Bottom Line

While not a majority, 33% of Americans believe alien spacecraft have visited Earth at some point. This group is potentially sympathetic to those who want to uncover what the government knows about alien landings, once and for all.

Another third or so of Americans may assume the government isn't being completely transparent about what it knows, but not because it is hiding something. For example, they may believe officials are keeping quiet because unidentified sightings could unnecessarily alarm the public, or because refuting UFOs would require disclosing sensitive military information.

Regardless of what Americans think of UFOs or the government's awareness of them, the subject is part of the nation's consciousness with 86% of U.S. adults saying they have heard of or read about unidentified flying objects.

Something odd is stirring in the depths of Canada's Kidd Mine. The zinc and copper mine, 350 miles northwest of Toronto, is the deepest spot ever explored on land and the reservoir of the oldest known water. And yet 7,900 feet below the surface, in perpetual darkness and in waters that have remained undisturbed for up to two billion years, the mine is teeming with life.

Many scientists had doubted that anything could live under such extreme conditions. But in July, a team led by University of Toronto geologist Barbara Sherwood Lollar reported that the mine’s dark, deep water harbors a population of remarkable microbes.

The single-celled organisms don’t need oxygen because they breathe sulfur compounds. Nor do they need sunlight. Instead, they live off chemicals in the surrounding rock — in particular, the glittery mineral pyrite, commonly known as fool’s gold.

“It's a fascinating system where the organisms are literally eating fool's gold to survive,” Sherwood Lollar said. “What we are finding is so exciting — like ‘being a kid again’ level exciting.”

Sherwood Lollar is excited not only because of the peculiar the mine’s rock-eating life seems, but also because of the growing realization that strange forms of life might not be so peculiar after all. Scientists are starting to find similar microbes in other deep spots, including boreholes, volcanic vents on the bottom of the ocean and buried sediments far beneath the seafloor.

“The deep microbial realm reveals a biosphere that’s more extensive, resilient, varied and strange than we had realized,” said Robert Hazen, a mineralogist at the Carnegie Institution’s Geophysical Laboratory in Washington, and co-founder of Deep Carbon Observatory, a global project to study the deep biosphere.

Cut off from light, air, and any connection to the surface, this shadowy realm seems more like an alien world than part of Earth. Hazen said exploring it could help us understand how life might have begun on other planets as well as on our own. We might even find alien-like creatures living undetected right beneath our feet.

Lots of life at the bottom

Sherwood Lollar’s work builds on a 2018 report by Deep Carbon Observatory scientists who tried to map the total extent of Earth’s deep biosphere comprehensively for the first time.

In the eye-opening report, a team led by Cara Magnabosco, a geobiologist at the Swiss technical university ETH Zurich, estimated that some 5 x 10^29 cells live in the deep Earth: that’s five-hundred-thousand-trillion-trillion cells. Collectively, they weigh 300 times as much as all living people combined. The team describes this hidden ecosystem as an “underground Galapagos.”

The denizens of the deep are an exotic bunch even beyond their appetite for solid rock. One species, the microbe Geogemma barossii, can live at temperatures of 250 degrees Fahrenheit — well above the boiling point of water and close to the theoretical limit at which vital organic molecules start to disintegrate.

Separate studies of material drilled near the Mariana Trench in the Pacific Ocean hint that some organisms could be living six miles below the seafloor, limited only by the heat at such tremendous depths. Laboratory experiments show that some microbes can tolerate pressures 20,000 times higher than the air pressure at sea level, meaning that there are almost certainly more extreme ecosystems out there than the one in the Kidd Mine.

“We’re finding that we don't really understand the limits to life,” Sherwood Lollar said.

The pace of existence in the deep also seems radically different from that on the surface. In ancient environments like the trapped waters at the bottom of the Kidd Mine, food and energy are scarce. To compensate, cellular metabolism slows almost to a standstill.

“Many of the microbes may survive for thousands of years or more without dividing, just replacing their broken parts,” said Karen Lloyd, a University of Tennessee microbiologist who studies life at the bottom of the ocean.

There are so many deep microbes that, despite a seemingly lazy existence, they collectively exert a huge impact on their habitats. For instance, a community of cells on the ocean floor consume methane gas that bubbles up from ancient sediment. “Deep subsurface microbes eat massive amounts of methane that would otherwise be released,” Lloyd said, helping curb atmospheric levels of a potent greenhouse gas.

Back to beginnings

One of the big questions facing Sherwood Lollar is how the deep-life community at the Kidd Mine is related to those found in other mines or stretched out beneath the oceans. “The number of systems we've looked at so far really is limited,” she said, “but they probably had a single origin at some point in life’s 4-billion-year history.”

If so, there should still be clues about when and how life first colonized the deep.

Fossils show that surface life has changed enormously over billions of years, but slow-motion deep life may retain much of its primitive characteristics. That’s especially true at the Kidd Mine, which is in one of the oldest, most stable portions of Earth’s crust. (The rock in and around the mine have lain undisturbed for 2.7 billion years, and have been cool enough to support life for at least 2 billion years.)

Sherwood Lollar wants to sequence the genes of the Kidd Creek microbes and then do a 23andMe-style analysis to unravel their kinship to other residents of the deep Earth: Are they all still close relatives, or have they diversified and adapted significantly to their local environments? It’s a delicate project, but she hopes to have results within a year or two.

Such studies could offer hints about where life first arose on Earth. Charles Darwin imagined the beginning might have occurred in a warm little pond, but “there's absolutely no reason why it could not have been a warm little rock fracture,” Sherwood Lollar said. In many ways, she noted, sulfur-breathing microbes living beneath thick, protective layers of rock would have been well suited to the brutal conditions on our planet when it was young.

Another, even wilder possibility is that life originated more than once, with other forms still surviving somewhere on Earth. “We've literally only scratched the surface of the deep biosphere,” Hazen said. “Might there be entire domains that are not dependent on the DNA, RNA and protein basis of life as we know it?” Perhaps we just haven’t found them yet.

Paul Davies, a physicist at Arizona State University, has long advocated systematic searches for such “shadow life.” The recent forays into the deep biosphere show how it might be done. Since known organisms cannot survive above 250 degrees Fahrenheit, Davies suggests going to extreme environments (around undersea volcanic vents, for instance) and checking for anything that appears alive at temperatures around 300 to 400 degrees Fahrenheit.

"That would stand out as a candidate for shadow life,” he said.

Ever cautious, Sherwood Lollar points out that she hasn’t found any evidence of shadow life at the Kidd Mine. But she heartily agrees that scientists need to keep a wide-open mind about what could be lurking within the deep world: “We see only what we look for. If we don't look for something, we miss it.”
