Edgar Mitchell, an Apollo 14 astronaut who once held the record for the longest space walk, has spent the past year telling anybody who wants to hear that we've made contact with space aliens multiple times, and NASA is covering the evidence up.

He shouted it loud and proud again yesterday during a press conference for Paradigm Research Group, an organization that lobbies for the release of government information on UFOs.

Does having a decorated old astronaut on their side make the UFO truthers claims more credible to you, or will you only start taking them seriously when they start providing the hard evidence?
