The search for signs of intelligent life in the universe may have to skip Oxford University.

A spacey professor at the austere British institution claims bug-like aliens walk among us, and says they’re having very close encounters with humans — interbreeding to create a new hybrid species that could one day save Earth from climate change and other disasters.

The visitors are hardly altruists — they are meddling in our affairs because they share a “comprehensive biosphere” with humans, according to Dr. Young-hae Chi , an instructor in Korean at Oxford’s Oriental Institute.

“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,” explained Chi, who has penned a new book in Korean on the topic called “Alien Visitations and the End of Humanity.”

It’s no coincidence that the visitors are appearing now that Earth is facing major problems, such as nuclear weapons proliferation and climactic change, he said.

“Judging from the way the ETs are acting, they have a better view of our future, perhaps it is pointing to a pessimistic future,” Chi told the Oxford Student campus newspaper this past week.

“It may be more or less assumed that the hybrid project is a response to this impending demise of human civilization,” Chi said in a 2012 lecture where he first introduced the possibility of the hybrid race.

There are four types of aliens, Chi told the campus paper: “Small; tall and bold; aliens with scales and snake eyes; and finally, insect-like.”

Alien hierarchy is truly a bug’s life, as the insect-like ones rank highest on the totem pole and probably boss around the others, Chi said.

“I don’t think they are from far away, they are just next to us, we can’t see them,” he said, reasoning that human perception is limited by our organs. It’s unclear if a human would even realize if he or she encountered one.

Yet despite their primitive appearances, Chi said the ETs are highly intelligent — as, too, are their half-human offspring — and therefore the only creatures smart enough to tackle planetary problems such as climate change and nuclear disaster.

But why fuss with humans?

Chi has three theories: Either they find human DNA valuable for preserving their species; they want to create a species that can survive future climate calamities; or they are trying to produce an intelligent future leader.

Chi said he’s searching everywhere under the sun to support his theory, but he still needs “more evidence to support my view.”
