Renowned for being the first British person in space, Dr. Helen Sharman is making headlines for another claim. She believes aliens exist.

"Aliens exist, there’s no two ways about it," Sharman said in an interview with The Observer magazine. "There are so many billions of stars out there in the universe that there must be all sorts of different forms of life."

Sharman said she was not sure if they would be composed of carbon and nitrogen, but suggested they may be on Earth already. "It’s possible they’re here right now, and we simply can’t see them," she added.

NASA DENIES THERE ARE LIVING 'INSECT- AND REPTILE-LIKE CREATURES' ON MARS

The 56-year-old Sharman went into space in May 1991 as part of Project Juno, a joint Soviet Union–British mission where she visited the Mir space station for eight days.

NASA has repeatedly denied it has discovered the presence of life outside of Earth, including most recently in October, when a former employee published an explosive op-ed suggesting the agency found life nearly 50 years ago.

Gilbert Levin, who worked on the Viking missions to the Red Planet during the 1970s, published an op-ed that made it clear that he believes data from the Labeled Release (LR) in 1976 was supportive of finding life.

"On July 30, 1976, the LR returned its initial results from Mars," Levin wrote in the op-ed, entitled "I’m Convinced We Found Evidence of Life on Mars in the 1970s."

NASA reiterated its previous stance that it has not found the presence of extraterrestrial life in the solar system. "Although we have yet to find signs of extraterrestrial life, NASA is exploring the solar system and beyond to help us answer fundamental questions, including whether we are alone in the universe," a NASA spokesperson told Fox News. "From studying water on Mars, probing promising 'oceans worlds,' such as Enceladus and Europa, to looking for biosignatures in the atmospheres of planets outside our solar system, NASA’s science missions are working together with a goal to find unmistakable signs of life beyond Earth."

Fox News has reached out to Sharman with a request for comment for this story.
