Aliens need no introduction. Over the years we've seen so many conspiracy theories on the existence of aliens, or so the government says.If you query a search of Aliens on Google, you'd be overwhelmed with the results especially when you begin watching hundreds of videos evidently showing the existence of Aliens and their sighting on our planet. I've seen dozens of such videos and watched another dozens of witnesses who claim they have had contacts with Aliens. Some have gone as far as claiming to have been abducted and returned. Whatever the case, some of this videos are jaw dropping and very compeling which leaves me thinking..... .....ARE ALIENS REAL?
