Oh, I think there's life out there somewhere... but I believed that even before the proof of water on other planets was found.

Astronauts are humans. Humans need water for survival. Astronauts are not let lose on a planet to go look for water, like some explorers did four or five centuries. They are ably aided by the knowledge gathered by other scientists. Before an astronaut is sent onto a planet the mission planners who send him have to ensure their survival there with nothing going wrong (with a 1 in million chance). Then the astronaut is told the full picture as to what he should do to find water, put it in liquid form or to recycle and so on and so forth. Only with all this knowledge he is sent and sets foot on the new planet. It is the reason why we are still in the planning stage regarding 'Man on Mars' mission, for example. It is an altogether different story with Moon, which is just too near us; where a man (astronaut) can be sent for a few hours with a simple mission (like collecting rocks or to place an instrument) and retrieved back.

In fact, we now have evidence of water (past or present) on almost every body in the solar system. Water alone is not sufficient to demonstrate the presence of life -- let alone intelligent life. For example, the mantle of Triton could be highly pressurised water at almost 200 C, with dissolved radioactive elements (from its contact with the satellite's rocky core). I don't expect to find any "Tritonians" soon.

even though we now know that there is water on other planets but that doesnt mean that it can result in creation of life.
being water is one thing and the conditions of atmosphere is other.. but both are essential for the life to survive. i agree with the point that the first life on earth occured when there was no oxygen in the atmosphere but the earth was cool.. so if a planet is cool (not too cool) and satisfies other conditions like it has minerals and all, then life could originate on the planet..!!

We definitely are not alone.
Icy chasms on one of Saturn's most humble moons, hidden amid its glorious rings, have overtaken the sands of Mars and the stratosphere of Venus as the most intriguing potential hiding place for alien life in our solar system.
Astronomers and astrobiologists, who are always looking for signs of life far from Earth, were caught by surprise — and they remain so, unable to explain how such a small celestial body (only 318 miles wide at its equator ) can pump out so much water.

I have long believed that we are POSSIBLY not alone. I will believe we are DEFINITELY not alone when I see credible evidence of life off Earth. Evidence as good as we have for the water.

yes, because if there is water, then there is life
