His disappearance has sparked major interest online after a bizarre vimideo of his bedroom was leaked online, with some suggesting he has been taken away by a UFO.

Many are suggesting the young man, from Brazil, was trying to complete the work of Giordano Bruno, who was one of the first thinks to predict the existence of extraterrestrial life.

While an eerie self-portrait of the student with an alien was discovered on his wall.

Police say “all possibilities are being considered” and his family revealed he was working on a secretive project before he vanished.

Relatives say he was constantly asking them to help him fund the scheme – but refused to give more details only saying he was writing a series of books that would “change humanity in a good way”.

Bound manuscripts – each with Roman numerals on it – were also found in his room, which have been decoded by a Brazilian computer expert.

“It is difficult, as an adult, to understand that you were wrongly taught what you suspected was correct since you were a child.

“In other words, if you fit into the system, your behaviour will be determined, making you at the mercy of beliefs already provided and well established in dogmas and rituals, with the masses.”

Mr Borges was last seen by his family when they went for a meal in Rio Branco before his parents went away.

Mr Borges reportedly kept his room locked for 24 days while his parents were away, according to his older sister Gabriela.

She said: “He said it was his project, I questioned him because I, as a sister, didn’t know what the project was and he told me that he would tell me what it was in two weeks.

“He was an adult and it was his privacy.

“It bothered me, but I couldn’t exactly break down the door.”

His mother Denise admitted her son was interested in extraterrestrial life, according to the Daily Star online.

She added: “He only told me that he was writing 14 books that would change mankind in a good way.

“He wanted to patent them because he had created a new theory.

“He asked me for help and I said I would read them.”
