Humanity has yet to make contact with aliens, and a retired US Navy Admiral has proposed a radical reason why: they are hiding in our oceans.

Tim Gallaudet, a former acting administrator of the National Oceanic and Atmospheric Administration (NOAA), recently explained why Earth's deep ocean may be the perfect hiding spot.

Speaking on the Hang Out with Sean Hannity podcast, Gallaudet said: 'If they were to go somewhere basically to not be detected for a period of time... where would you want to go?

'You'd want to go... [to] the most unexplored area of the world, and that's the ocean.' 

After decades of studying the ocean, Gallaudet believes its largely uncharted depths could conceal phenomena that have so far escaped detection. 

'We've only explored with either drones, buoys [or] floats, about 10 percent of ocean volume,' Gallaudet said. 'So there's a lot of mystery out there right now.' 

His comments come as a UFO researcher claims to have found an entrance into an underwater alien base off the coast of Canada.

Scott C Waring uncovered a mysterious hole in the waters surrounding Nunavut, which he claimed was more than 3,000 feet across and about 32 feet below the surface.

During the interview, Gallaudet highlighted a video he claimed showed mysterious objects moving underwater before jumping out to the surface.

'It goes into the ocean, no disturbance,' Gallaudet told Sean Hannity during the podcast. 

'I'm aware of another video that shows something similar, but from overhead... so yeah, there's something that they've been able to engineer that we have no idea how to reproduce,' he added. 

Gallaudet claimed the objects could break the sound barrier without the thunderous boom that normally accompanies supersonic flight, a feat he said defies explanation with current technology. 

He testified under oath before Congress in 2024, claiming there was a 2015 incident involving near-midair collisions with UFOs during a carrier strike group exercise and the subsequent disappearance of an urgent email report about the event.

The former admiral also asserted that Earth is visited by non-human intelligence utilizing advanced technology with extraordinary flight and transmedium capabilities. 

While Gallaudet has never provided locations where UFO bases could be hiding, Waring believes he has found the entrance to one.
