there is no definite evidence of an alien presence

L’intelligence americana was unable to find confirmation of the presence of aliens in space. CNN writes it underlining that for US officials the unidentified flying objects encountered by US Navy pilots in recent years cannot be defined as alien spaceships. However, these objects have not been identified, as sources cited by the New York Times explain in a UFO report due to be delivered to Congress later this month.

However, three of the five sources cited by the newspaper have not ruled out a possible alien presence in space. The possibility that these objects belonged to Russian or Chinese aircraft was also not ruled out, thus raising questions about national security, one of the sources said.
