He wants to believe.

The former head of the Pentagon’s secret, $22 million UFO-hunting program says aliens may have visited Earth.

“My personal belief is that there is very compelling evidence that we may not be alone,” Luis Elizondo, former leader of the so-called Advanced Aviation Threat Identification Program, told CNN on Monday night, noting he does not speak for the federal government.

The program ran from 2008 to 2012, when the Department of Defense investigated eerie reports from military air personnel and commercial pilots about strange objects they’d seen in the sky.

Elizondo argued Monday that the aerial stunts the UFOs performed — such as hovering without any sign of propulsion — are beyond the reach of human technology and were “seemingly defying the laws of aerodynamics.”

“These aircraft — we’ll call them aircraft — are displaying characteristics that are not currently within the US inventory nor in any foreign inventory that we are aware of,” he said.

And even if human vessels could pull off such moves, our frail earthling bodies would likely be crushed under the ensuing G-force, he added.

“We have identified some very interesting, anomalous type of aircraft — we’ll call them aircraft: things that don’t have any obvious flight services, any obvious forms of propulsion, and maneuvering in ways that include extreme maneuverability beyond, I would submit, the healthy G-forces of a human or anything biological,” Elizondo said.

After the Advanced Aviation Threat Identification Program was dismantled, many employees were simply shifted to different areas of the Pentagon — and they still hunt for flying saucers part time.

Elizondo left the federal government and does work for the research group To The Stars Academy of Arts and Sciences, a group founded by the former singer and guitarist from the rock band Blink-182, Tom DeLonge.
