Even US Apollo 14 Astronaut, Edgar Mitchell has been on record stating that he saw aliens on his voyages.
Well, it would not "be an act of aggression" by NASA as some people said, in the article. We are already at war with Aliens, by many reports, and I have seen a video of what appears to be two alien space craft in the outer Earth atmosphere shooting weapons at each other.
PS: the guy in the video is an idiot! He doesn't have any clue about this subject. Probably made the video to impress some girls or something.
