Should we start thinking about etra-terrestrial life again ... ?

Conceded, water is a sign of extra terrestrial life. But presence of water alone doesn't suggest anything. I am not cynical, nor am I stating that we are alone in the universe. But aren't we jumping to conlusions too soon?

Isn't that how scientific knowledge advances? By jumping to conclusions (more formally known as "formulating hypotheses"). The key is to realise when one's testing of such conclusions is clouded by nothing more than determination that they must be correct!

Very well put ashwil. One must not forget:

"There are two possible outcomes: If the result confirms the hypothesis, then you've made a measurement. If the result is contrary to the hypothesis, then you've made a discovery." -Enrico Fermi

"In the real world, this would be a problem. But in mathematics, we can just define a place where this problem doesn't exist. So we'll go ahead and do that now..."
