Australian scientist Dr Karl Kruszelnicki, in a recent radio interview, has scotched claims by Apollo 14 astronaut Dr Edgar Mitchell that UFO activity, and alien visits to Earth, have been been covered up by world governments.

But why would they keep it secret? I mean do they think that if we know that there’s a life form from another planet that we’ll all suddenly bite ourselves on our belly buttons? Well, what will do? We’ll say yeah, bring them on “hello, how you going mate”. Or is it that there doing some sort of secret stuff with the government and trying to steal our brains? Show me the proof. All I want to do is see the proof; and the proof is really easy. You just get one of your alien mates to land their UFO in the middle of the football field on some sort of football grand final: round ball, AFL whatever. And that’ll convince everybody in the world really quickly.
