“Aliens have probably already visited Earth.”

Since May, the Pentagon has been releasing declassified UFO files, more than 200 so far, and Pentagon officials say many cases remain “unresolved.” The Pentagon’s anomaly office says it has found no evidence that any of them are extraterrestrial. In early October, NASA’s chief said he is staying open-minded about the sightings. Roughly half of Americans already believe aliens have visited, so the question is whether unexplained sightings add up to “probably” or just “unknown.”

Mike Gold, former NASA UAP study team member (leans agrees): He says “the public can deal with the fact that we’ve had an extraterrestrial crash retrieval program.” He also calls himself “violently neutral” and says to “let the data speak for itself.” Kelsey Johnson, University of Virginia astronomer (disagrees): “None of them, to my assessment, lead us to any credible conclusion of aliens.” She says “unexplained” does not mean “extraterrestrial.” Jared Isaacman, NASA Administrator (middle): “If it’s aliens, I think NASA should have a seat at the table.” He leans toward natural phenomena or secret next-generation technology, and says “we couldn’t tell you conclusively that there isn’t life in our own backyard.”
