Many experts have previously theorized that aliens are already on the planet or they already know about our existence. However, a new theory by another expert suggests that aliens have already bred with humans to create alien-human hybrids to save Earth.

An expert from Oxford University, Young-hae Chi, put forward a theory that aliens are interbreeding with humans to create human-alien hybrid species that will eventually save Earth from total destruction by climate change.

Believing in correlation between alien abductions and climate change, Chi said that it was ‘not only scientists and theologians, but also non-human species who appear to be greatly concerned about the survivability of the human species’.

He said that reversing climate change would not only save Earth, but would also prove to aliens that their low opinion of humans’ moral capacity was incorrect, reported Daily Mail.

Chi claimed that aliens exist in their own bio-system, which cannot be experience by humans. He categorized aliens into four types; small, tall and bold, scaly with snake eyes, and insect-like. Out of these Chi believes that insect aliens may be in charge and give orders to the other types, as per The Sun.

Since the aliens are super intelligent, they can possibly solve the problems on Earth in the future, such as climate change, and hence save humanity from mass destruction, believed Chi. “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.”

For now, Chi stated that he was still looking for further evidence to support his views about the already-present alien-human hybrids. “It may be more or less assumed that the hybrid project is a response to this impending demise of human civilization.”
