Well,.......
i am always amazed when they land on some god forbidden planet and say they cannot find any form of life, so therefore none exists!
they are only searching for life under our definition of life....needs water and oxygen.
pwhat if the planet is home to, for example, a relative of the cluuuusbanian spoogle. This could eat rock, breathe **** all and defecate dust.....and we would never know. I for one, if I saw a fricking great space thing land on my planet, would personally make myself like a disgraced TV presenter ( scarce)
.... Just ranting
