This is like saying that nothing can be unique, even individuals. We have no way at all of predicting the likelihood. And one expects that the occurrence of super-complex forms such as ourselves would be far less likley.
The fact is that organic life could quite easily be a phenomenon completely limited to this planet. Myself, I doubt there is anything remotely like us anywhere else in Eš

Anyway, I can play that game, too. The statement is illogical as it deals in an absolute (the certainty of ET) based on an unknown (the size of the universe). However, the observable universe is finite and becoming more and more 'known.' This is how [ame="http://en.wikipedia.org/wiki/Frank_Drake"]Drake[/ame] came up with his [ame="http://en.wikipedia.org/wiki/Drake_equation"]equation[/ame]. The most pessimistic figures entered into that equation produce a very lonely result, and the equation excludes all unknown variables.
Again, the search for life is not a science, it is only speculation with a massive budget.
Considering that a planet with water and possibly extremophile life, my dreams of living the cantina scene in Star Wars is one step closer to fruition
