Background/description:Area 51 is a top secret military base that lies in southern portion of Nevada. Built in the 1950’s it has since then been a testing ground for top secret military projects, like the U2 spy plane. So why do people thinks there aliens on the base? It is probably because of a man named Bob Lazar who 1989 claimed that he had been working on top secret projects involving aliens. A thing that also may have part is the isolation of the base and the little we actually know about what happens on the base.
Actually, there is no evidence to support the existence of aliens on Area 51. The only thing we can go on is Bob Lazars stories and those may not be true. Sometimes strange lights have been seen over the base, but they are most probably only secret military projects.
No evidence of aliens actually being on Area 51 have never been put forward and it is very unlikely that there are aliens there.
Based on the information we have on Area 51, it is very unlikely that aliens exists there. There have neither credible eyewitnesses nor any official government documents in support of the alien theory.
