With the more and more unexplained sighting one would have to come to a conclusion that aliens do exist. People including military people have come in close contact with UFO. UFOs have landed and have gotten significant scrutiny. People have come close to a lot of these craft. Although there are many people that have come close to an unidentified craft no one as yet come out and told about a meeting. Aliens may exist but until they actually make contact there will still be speculation.
