Actually I was just coming back in the car from the local shop when astronomer Dr Stuart Clark refered to the statement on Inside Science BBC4.He clarified the statement by saying that the Planets around the Earth had a unique placement compared to other solar systems and that the statement refered to this and a lack of similarity in both size and atmosphere of other planets.[around 16:45-22:20]

And that nicely brings up the subject of just what life we are actually seeking, after all being carbon based life forms are we limiting ourselves to this small perceptual basis.There may be life in a way on such planets as the Sun with its extreme high temperatures or Mars with its extreme low temperatures.In such cases the "life forms" may be unrecognizable to our limited understanding of science and even if they were somewhat similar to Earth bound life the lander onboard cameras would not pick them up due to the way they scan to compose images.

 

Could there be life forms that live in stars like the Sun that we have no clue even exist, sure. It's possible because we don't even know what we don't know yet, but it's extremely unlikely.

 

Right now we know that carbon based life exists, and we know that carbon based life has many advantages compared to silicon life because of it's chemistry. Carbon has more possible chemical reactions than silicon, and this we do know.

 

Looking for anything else, until there's evidence that it actually exists, is like hunting for Easter eggs in August.

 

Let's look for what we know can exist first, and once we've found that we can look for something else if there is any evidence that it might also exist.
