The other night, I came across this YouTube video, screen flickering in the dark, promising me “stunning” photographic of Nazi-engineered flying saucers.

The grainy footage, eerie music, and an air of “The truth is out there — and here it is!” reeled me in.

So, what’s the claim? In the expanded universe version of this urban legend, these Third Reich bozos not only built flying saucers using antigravity propulsion — one sportier model knwn as Die Glocke had a time-traveling option that caused it to bounce ahead to 1965 and crash outside Kecksburg, Pennsylvania. The story sounds like Steven Spielberg and George Lucas got hammered, whipped out a Ouija board, and channeled Ed Wood.

Let’s shatter this glass house right off the bat: Nazis were pipe-clogging turds who saw the world as their punchbowl. If they’d had technology as advanced as some of these UFO nuts insist, the Allies would’ve been screwed six ways to Sunday.

But let’s get real. The Nazis documented everything with Teutonic efficiency and an obsessive compulsion — from the horror shows at death camps to the pomp and circumstance of Nuremberg rallies.

Leni Riefenstahl filmed “Triumph of the Will” with a goddamn sense of aesthetic purpose. I mean, if you can make evil look that good on camera, why does your flying saucer footage look like Bigfoot took it while having a seizure?

Seriously, the evidence is shakier than Elvis in his final years. Blurred images, poorly exposed film — this is the stuff conspiracy theorists drool over.

I get it. The unknown excites people. But attaching this UFO myth to Nazi scientists is as absurd as claiming that John Williams is an alien because he composes damn good music.

Even if German scientists constructed a saucer-shaped conventionally powered aircraft, it’s a far cry from building a working UFO. We’re talking about engineering marvels beyond rocket science. Literally.

So why do people buy into this garbage? Wishful thinking? A desire to make the world crazier than it already is? If you ask me, folks latch onto these increasingly bizarre conspiracy theories the same way pornography addicts need to keep pumping up the kink to reach orgasm.

Let’s give a nod to the influence, though. These rumored German saucer designs left a mark on pop culture.

You’ve got George Adamski, who claimed contact with Venusians, sketching and photographing craft that eerily resemble this Nazi nonsense.

And then the TV show “The Invaders”? Their flying saucers could’ve been extras in that grainy Nazi film reel. Hollywood knows a good prop when it sees one.

Bottom line: Don’t buy into the hype. Nazis constructing flying saucers is as believable as me turning water into whiskey. And if I could, you bet I’d be a hell of a lot richer than I am now.
