When most of it collapsed into a big ball of matter, under its own gravity, it ignited nuclear fusion and our Sun was created. Rest of matter, which did not collapse into our Sun made the rest of planets with water on them. That's why our Sun is a billion years younger than all the elements on planets. The hydrogen and helium in our sun is old as universe, but life of our Sun counts from first ignition.

    It doesn't mean that our water was on other planets in other solar systems before coming to Earth. After explosion of Multanova water was flying through space for millions of years till it found earth and landed on it. Probably in shape of comets, the big snowballs in space. We don't have them too many now, but at the beginning of our system, there could have been billions of them, bombarding young Earth every minute.
    Finally, proof of intelligent life on Earth. Just when I was beginning to have some doubts.

    It is big finding, science made progress:

    "Scientists have confirmed that much of the water on earth is older than the sun — which could indicate the existence of life on other worlds.

    Researchers found that much of the water on Earth and across the system predates the sun, which could mean that other planets in the had access to water as they were being formed. That would likely be required to sustain life on any of those planets, as it has done on earth, the researchers said."

    Yes LeBrok, and of course devil is in details.

    The question is when and where the water (the ice) ensued.

    In interstellar medium before the Sun formation?
    or Inside solar nebula? http://en.wikipedia.org/wiki/Nebular_hypothesis

    In interstellar cloud of gases after explosing of Supernowa. When the cloud cooled enough oxygen and hydrogen fused together creating water.

    I think so, too.

    There is a difference between approaches of interstellar medium and solar nebula, in first case it is greater similarity between different planetary systems when interstellar ices/water are included into rotating circumstellar disks, in second case there would be much greater differences in terms of ice/water between different planetary systems in Universe, depending of more factors.

    If judging by abstract and newspaper articles authors gave some proofs concerning the first approach.

    Has anybody considered the possibility of human's depleting the natural resources on Earth and having the inhabit another planet? Such as water.

    What is your opinion of this ad?

    I agree with the author as our Universe is something such big that we can't even imagine and there must be some other creatures except us.

    Of course there is. The universe is huge. One thing I don't understand is why they're searching life on earth-like planets...I'm sure some weird creature could have evoluted in a way it can survive on a planet where we wouldn't survive a second.

    There are high possibilities that there might be Earth-like life in the astral zone of Epsilon Eridani. This system is very familiar to our Solar system.

    Think the Chinese informed on Tuesday,15th Jan 2019, that they had succesfully planted, and grew some plants on the moon ,but its reported that they had then died by Thursday,17th Jan 2019, due to the extreme cold conditions.

    If life is found it is going to be 'very very' different, to that on Earth. Look at the vast extreme differences of species of life found on Earth today, and those that we know previously existed. Earth has a very 'unique' history of differing enviroments throughout its existance. We are still finding new forms or species of life, on Earth yearly I believe, and there are many more to find no doubt.

    We have no idea what intelligence and life exists yet in space, but the idiots at 'Nasa' should never of sent that probe into deep space in my opinion, telling any 'life',' we are 'here' and 'Hello'. Earthlings may soon come to regret those actions by a 'very tiny few' that possibly could put billions at future risk.

    I also believe the only impression, any other alien life that comes across us, can possible have is negative, as they cannot fail to see, and understand the recent mess we create on our Earth, and the fact that we keep killing each other, and almost every, other species, that exists, we come across or we find here. Any sensible 'alien life' with even the very least grain of intelligence would rightly ignore us, probably as they have done up too now, or destroy us for there own future safety.

    There is today a recent set of opinions regarding the planet 'Mars', some people are pushing/supporting a view that evidence of two possible nuclear explosions exist there. They assume that these were 'manufactured explosions', and were responsible for totally wiping out all, or any life that was believed to of been in existance there, at that time.

    Space is a very violent place, and any life will no doubt have to be born or develope from this violence. Therefore any exterrestrial intelligent life must be aware, or have its knowledge of this, and looking for other life in space,, the way we have, might not be the best way forward. We could or might end up on some aliens plate, or stuck in some type of test tube...lol

    There is likely life somewhere in the universe. Does that life resemble humanoids? Little grey/green men with big eyes? Hell no! They likely resemble jellyfish.

    I think all this is possible. Sometimes it seems to me that my whole life is a complete dream, and when I wake up I will be committed by another person.
