I believe there is life outside/in (via wormhole maybe?) our galaxy. How can someone say there is no other life with the expanse of our universe??? Proof: mass sightings. I know we do not have craft that is as big or bigger than a football field. And what about the metal (not identified metal) that some people have had surgically removed after claiming to be abducted?
So how would objects in space; recorded by NASA, take 90 degree turns on a dime? How would you explain people knowing exactly where these metal anomalies are when they ask the surgeon to remove them? In Illinois, a "ufo" was spotted by five different police officers in different locations explaining the same exact craft. Hmm... maybe these policemen just decided to pull together and invent a story? I would think not. In Phoenix, Arizona back in 1997, thousands of citizens called in what they saw in the sky to be as big as two or three football fields. Even the governor at the time said he saw the lights slowly moving over the area. What country has that big of aircraft? And what kind of aircraft can cover miles in just a few seconds not to mention taking off within a split second? I think human kind is pretty arrogant thinking "nope...nobody here but us!" That's like saying there isn't any other animals in this Amazon rain forest except this little hill of ants.
