I believe that Aliens do exist . I also think our government is behind most of the sightings we see nowadays. Back in the late 30's and 40's those Alien encounters are the real thing. Now they are just engineering them.

And maybe We are the aliens on this planet. We shouldnt be here at all. We cant handle the sunlight we burn in the sun the gravity is too heavy for us too. Dont see many animals walking round with suncream and sunshades on these days.

Really hard to believe that in this big old universe we have we're the only ones alive. They're real we just don't realize it yet.
