An Oxford academic shockingly claimed that there are already alien “hybrids” roaming the Earth among us humans. These are species who are half alien and half human and were bred to survive cataclysmic phenomenon brought about by climate change.

The theory was shared by Korean lecturer Dr. Young-hae Chi, who also teaches at Oxford University’s Oriental Institute. According to the expert, these hybrids were born out of cases of alien visitations and alien abductions which have been reported through the years. Dr. Chi is a strong believer of these events and even outlined his theory in the book, “Alien Visitations and the End of Humanity,” which was published in Korea.

Oxford’s student body, The Oxford Student reported that the lecturer believes there’s a strong link between alien abduction cases and climate change.

“One possibility is that they find our DNA valuable for the preservation of the stock. Secondly, to create species which can survive in the future climate conditions. Thirdly, some abductees report that these hybrids are of very high intelligence, so are they producing these hybrids as a problem-solver, a future leader?” Dr. Chi said in an interview.

But this is where it gets bizarre. According to the lecturer, he believes that there are four types of alien species who could have interbred with humans and can be distinguished via physical appearances. There are those who are insect-like, those with scales and snake eyes, small aliens and tall and bold aliens. Among the four, the insect-like aliens are said to be the most dominant or ruling species.

Dr. Chi also explained that the main reason that they interbreed with humans is the survival of their species.

“So, they come not for the sake of us, but for the sake of them, their survival, but their survival is actually our survival as well, the survival of the entire biosphere. That is where I progressed in developing my theory and I’m still looking for more evidence to support my view,” he said.

What’s alarming about his theory is that the interbreeding of humans and aliens could signify the end of human civilization. Speaking in 2012 during the Anomalous Mind Management Abductee Contactee Helpline Conference (Ammach), the lecturer outlined that colonization is the main reason why aliens come to Earth and abduct people.
