A Montana Tech University professor has said that the aliens aboard UFOs could be our time-traveling counterparts.

Dr. Michael Masters recently claimed that alien spacecraft or UFOs that people saw previously could have contained humans from the future. As opposed to conspiracy theories that UFOs that come to the Earth contain aliens, Masters' theory is a bit closer to home. According to him, humans would use contraptions to travel back in time to understand their past.

Many people who claimed they saw aliens usually describe them as having human-like features. Masters, who specializes in human evolution, supports his theory by citing several cases of UFO sightings. Even though Masters is admittedly skeptical about his theory as well, he did defend his claim in his book “Identified Flying Objects.”

For Masters, the reason why people see human-like features from the aliens they saw is that they are a form of advanced humans. With a doctorate in anthropology from Ohio State University, the professor tried to link the UFO observations and his theory in his book using science. As he claimed, our time-traveling counterparts or "extra-tempestrial" are bipedal. They also have five fingers on each hand and five toes on each foot. They walk upright with a bi-lateral symmetry featuring two eyes, a nose, and a mouth. As our counterparts, they can also contact us using our language.

"I continue to remain vigilant in my own scepticism. I do not have a staunch unwavering devotion to this notion, and I do not claim to proclaim a truth," Masters said.

He also noted that he stands by his theory and is willing to talk to anyone about it. He went on to say that the book he wrote was written for his academic peers as much as it is available for anyone from the UFO community.

Likewise, Masters wants his book to encourage scientists to entertain the discussion on aliens including how UFO sightings could be real events involving extra-tempestrial. He added that the advanced technology and humanoid form of the creatures came from continued human evolution on Earth.

Additionally, Masters encourages readers to think more about human evolution and how it can eventually result in people piloting the UFOs through time travel.
