Dr Michael P. Masters, an anthropology professor from Montana Tech University, Montana, US, claims decades of UFO sightings and encounters have been mistaken and are actually distant descendants coming back to visit.
The doc has presented the bizarre theory in his new book titled “Identified Flying Objects: A Multidisciplinary Scientific Approach to the UFO Phenomenon” which examines the long-term evolutionary change in human biology, culture, and technology.
A key piece of evidence that leads the professor to this theory is when most people report close encounters with aliens, they always seem to describe them in the same way.
Most sightings describe the supposed aliens as standing upright walking and have five fingers on each hand and foot.
The so-called terrestrial beings are bilateral, symmetric and they have two eyes, a mouth, a nose.
Many also claim they can communicate with us in our own languages.
“The phenomenon may be our own distant descendants coming back through time to study us in their own evolutionary past,” Michael said.
Alien abductions and medical examinations, in his opinion, prove time travellers are anthropologists much like himself.
The anthropologist, who specialises in UFO sightings, said these encounters can be explained scientifically, even if sceptics might consider this fringe science – an established field of study which departs significantly from mainstream theories.
Dr Masters said: “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 the truth.”
Dr Masters claimed going back in time to study ancient humans would be the “holy grail of palaeontology”.
