With the closure of the Ministry of Defence desk specifically dealing with claimed alien encounters in the UK, we now have no formal department to analyse - or respond to - any potentially legitimate claim. In other words, if E.T. phones home, all he'll get is 'number unobtainable.' But how likely is a call from E.T. in the first place? Well, let me put it this way: I'm not a conspiracy theorist but I do believe in aliens. I also believe in interstellar spaceships and life on other planets. Is this rational? Far from being outlandish, this is the only logical conclusion to draw about the universe and our place in it.
