Though we are yet to find alien life, some scientists are suggesting that alien life has already found us and are intentionally hiding the truth to avoid human shock.

A group of scientists at the METI (Messaging Extraterrestrial Intelligence) International meeting recently suggested that intelligent aliens have already discovered us and are keeping in a kind of ‘galactic zoo’ by simply just watching as without revealing themselves because humans would then struggle to cope up with the reality of their existence.

“It seems likely that extraterrestrials are imposing a ‘galactic quarantine’ because they realize it would be culturally disruptive for us to learn about them, said co-chair Jean-Pierre Rospars, according to Forbes.

The researchers claimed the ‘zoo hypothesis’, which means that aliens are aware of Earth and observing us just as the way we observe animals kept in a zoo. METI President Douglas Vakoch said that if this is the case, humans should increase their efforts to create messages capable of reaching our ‘keepers’, to show off our intelligence, and get the ‘galactic zookeepers’ to reveal themselves.

“There’s no reason to think that humans have reached the highest cognitive level possible. Higher levels might evolve on Earth in the future and already be reached elsewhere,” said Rospars.

The meeting was held to explain a mystery dating back to many years, called the Fermi Paradox. The conundrum was initiated back in 1950 by physicist Enrico Fermi and revolves around the question that where are the aliens.

Meanwhile, though we are still looking for extraterrestrial life, there have already been hundreds of distant worlds and exoplanets found with more to be out there, reported Live Science.
