Take a second to think about all the alien invasion movies you've seen.

Start with Independence Day, World the World, Arival, of course, Men in Black,

and my all-time favorite Stephen Spielberg's movie, Close Encounters of the Third Kind.

I mean, in almost every one of these films, there's one iconic scene, some variation of this.

A giant shadow is cast over an entire city.

People look up to the sky, their jaws drop on the floor.

I mean, some of them drop their coffee cups,

and then lasers erupt from a massive spacecraft,

blasting the pavement as everyone runs for their lives.

Or the aliens come in close proximity,

offering to help us or save us.

But regardless of how the scenes play out, most of these movies

suggest our intergalactic enemies will come from above, that they'll descend from the heavens in their

giant aircraft, sizzling us like ants under a magnifying glass on a hot summer's day.

Now, of course, I can't guarantee that won't happen one day.

But Rasha and I recently learned an alien invasion might not unfold the way Hollywood tells us it will.

There's a theory that says ETs have actually been right here on Earth for centuries,

not above us, but below us.

Which is why today we want to talk about U.S.O's, otherwise known as unidentified, submerged objects.

Because if the evidence is to be believed, the invasion might not emerge from the clouds,

but instead from the watery depths of our planet.

And we might be powerless to stop it.
