Until proof can be found outside of earth's influence, there will always be doubt. But, all it takes is fining one little bacterium or microbe on Mars, or Europa, and it's a whole 'nuther ball game.

No, it means that, statistically speaking, it's incredibly likely that there is life on other planets.

Absence of Proof does not mean Proof of Absence is the answer to that

You may have no doubt, the rest of us will wait for proof.

I can't recall the late great Carl Sagan saying this but it would not surprise me in the least if he did. He did however say in his novel 'Contact': "The universe is a pretty big place. If it's just us, seems like an awful waste of space"

Yes he did and no, that is not what he meant.

Billions of planets makes life likely, but until we find it we can't know for sure. It is possible that the formation of life is so improbable that it only happened once in the whole universe.
