Voir la source de Aliens already exist on earth

 Work on deciphering a complex set of symbols sent to them is underway, scientists from the country's Space Research Institute said.

They claim aliens are currently answering 30 questions posed to them.

Lachezar Filipov, deputy director of the Space Research Institute of the Bulgarian Academy of Sciences, confirmed the research.

He said the centre's researchers were analysing 150 crop circles from around the world, which they believe answer the questions.

"Aliens are currently all around us, and are watching us all the time," Mr Filipov told Bulgarian media.

"They are not hostile towards us, rather, they want to help us but we have not grown enough in order to establish direct contact with them."

Mr Filipov said that even the seat of the Catholic church, the Vatican, had agreed that aliens existed.

He said humans were not going to be able to establish contact with the extraterrestrials through radio waves but through the power of thought.

"The human race was certainly going to have direct contact with the aliens in the next 10 to 15 years," he said.

"Extraterrestrials are critical of the people's amoral behavior referring to the humans' interference in nature's processes."

The publication of the BAS researchers report concerning communicating with aliens comes in the midst of a controversy over the role, feasibility, and reform of the Bulgarian Academy of Sciences.

Last week it lead to a heated debate between Bulgaria's Finance Minister, Simeon Djankov, and President Georgi Parvanov.
