The United States Air Force’s base in Nevada has long been linked to alien testing due to its high classification.
And now they may have accidentally spilled the beans on what really goes on after something appears to have broken out of the ground.
The discovery was spotted on Google Earth by an eagled-eye viewer and it appears to show a hole roughly four miles from the facility.
He said: “This is getting really weird.
“It’s some kind of structure, a hole, it seems it is extruding something very strange – almost like tentacles.
“Is this some kind of entrance that has released something out of this world?”
Yes. But if we told you what it is we'd have to kill you.
