UFO and aliens are two different things , but as far as aliens goI get the impression that most of you have a 'closed-mind'when it comes to this subject.Incredible.The US Government,Military,and past US Presidents all acknowledge the existence of UFO's;and,therefore alien life itself.The Holy Bible is One of the Best Sources of UFO Encounters.I just don't understand you people.Perhaps,many of you never have seen a UFO;but,I have,and quite close up.How many of you have ever heard of the Virile Society prevalent in Germany during WWII.Check what Wernher VonBraun,himself,said about where Germany got it's advanced Rocket Technology.
there is evidence that there were aliens on the moon.
But nowhere else in the universe have we found such evidence.
It may be possible there are , but slim we would find it anytime soon. As far as chemical rockets go , they would never take us to the stars , so Wernher von Braun got shafted by any extraterrestrials that gave him technology.
Oh but here is the evidence that aliens were indeed on the moon.
Other than that there is no evidence of aliens except in mythology and urban legends.
