What's it like to be abducted by aliens...and live to tell about it? Calvin Parker says it happened to him in 1973, and he's telling all in his first-ever nationally-televised interview on Travel Channel's new series, UFOs: The Lost Evidence.

On Sunday’s all-new episode, Parker relives the night of October 11, 1973, detailing his chilling run-in with several extraterrestrials. Nineteen-year-old Parker was looking for a spot to fish on the Pascagoula River with his pal Charlie Hickson when the terrifying incident occurred. It’s a night he says he’ll remember for the rest of his life.

In a Travel Channel-exclusive clip of Sunday's interview (below), he recounts the chilling tale.

"Then she took a finger and run it down my throat," says Parker, "tried to come up through my nasal cavities, and that's when I started trying to come back to."

According to The Washington Post, the location of Parker’s purported encounter has been granted a historical marker, designating it as one of the "best-documented" cases of alien abduction.

Parker’s tale is just one of several to be covered on UFOs: The Lost Evidence's upcoming episode titled “UFO Abduction."

UFOs: The Lost Evidence unveils the latest, never-before-revealed audio, video and documentary evidence of extraterrestrials directly from government officials, the military and police, scientists and professors, as well as eyewitness testimonies.
