Its one of those subjects I try to leave alone as it is potentially a bit spooky, but I think:
1) yes. There probably is extra-terrestrial life.
2) At a guess, no. They don't visit us. Perhaps some are real but I think its our interplentary ego at work.
Purely on a hunch I think the video is a fake. It is well done however so maybe from a movie? The sort of questions being asked are not very specific and it doesnt strike me as the kind of interrogation that it is real. The intelligence agencies would only start asking about the meaning of life and how the universe once theyve established the alien is not a security threat.... Which is a
massive subject in terms of understanding an alien civilisations capabilities in terms of weapons, faster than light speed travel, etc.
The name EBE-3 appears to relate to the mythology around the Roswell incident. the alien also speaks English without apparent difficulty and appears to have "new age beliefs".
(Is this promotional material from the new alien invasion movie "arrival"? I cant load Youtube atm so I'm not sure. Its not beyond the film industry to exploit our fascination with these questions to get us to watch their stuff).
But yeah. I am second guessing myself here. This is well done assuming its fake.
