Humans attempting to talk to aliens would be like ants trying to talk to people.
Humans won't be able to have conversations with aliens
Experts are convinced that humans are mentally inferior to extraterrestrials and would struggle to make any conversation as it would be lost in translation.
Scientists believe that aliens are very smart because the solar system is 4.5 billion years old - compared to the 13.8 billion-year-old universe - and they have been around for far longer to develop superior intelligence to the human race.
Professor Michael Garrett, director of the Jodrell Bank Centre for Astrophysics in Manchester, said: "There might be other things out there that have a capacity that is completely beyond what we can even imagine.
"It's a bit like ants trying to communicate with humans."
Dr. Louisa Preston, an astrobiologist at University College London, added: "I bet we are like ants. We have really inflated egos about our ability to think."
