The scientist of NASA Silvano M. Colobano says aliens look different from people or any other form we know and that they have technologies that cannot be imagined.
They also have capabilities for inter-air space travel, Kosovo Press broadcasts. This statement comes after NASA started scanning the universe as part of its “Research for External Intelligence” program.
I just want to stress whether we can find them or they can find us if they haven't already done it they can't have our structure,” said Colobano.
He believes scientists today are more focused on finding signs of modern human technology on other planets, reports the Daily Mail.
“This means that they can lose the signals of civilizations that are much older than Earth”, says Colobano.
Space expert also said that not every unidentified alien object, UFO can be explained or confirmed.
