I read this headline over the weekend, and according to the news story aliens may be living among us. Two Australian researchers, Professor Paul Davies and Dr Charles Lineweaver, outlined their hypothesis in the latest issue of the journal Astrobiology.
All of a sudden a lot of things make much more sense. Now I am not saying that my neighbours are aliens as the story carries on to say that the aliens in question are likely to be primitive microbes that sprang up some four billion years ago. At this time the Earth was being buffeted by a hail of meteors and giant asteroids during what's known as the Archaean bombardment.
Alternately, microbial life forms may have arrived on Earth from space and unobtrusively co-existed with us.
Maybe that constant ringing in my ears is my home planet trying to get in touch with me, however I think they keep getting the engaged signal.
