I'm not really the one to agree on these kinds of thing, nor the one to say that's not real, but let's face it, even though I strongly believe there must be some kind of life in the universe, we've had thousands of these short clips showing lights in the sky and whatnot.
I believe that if aliens really do visit Earth then it might be better for the government to be quiet about it, at least until they figure out the appropriate response. I mean, imagine the panic from close minded idiots and ignorant people in case we get a public announcement that aliens are real. People would go ape ****.
