Records from Barack Obama's tenure as US President contain thousands of pages relating to aliens.
The Barack Obama Presidential Library in Chicago has revealed that it stocks "3,440 pages and 26,271 electronic files" about the prospect of extraterrestrials following a Freedom of Information request.
Obama hinted last year that the US government was aware of the possibility that aliens could exist.
He told chat show host James Corden: "When it comes to aliens, there are some things I just can't tell you on air.
"But what is true is that there is footage and records of objects in the sky that we don't know exactly what they are.
"How they move, their trajectory. They did not have an easily explainable pattern. So I think that people still take that seriously and try to figure out what that is."
