    Yeah Mars suposed to have some liquid salt water.
    On the quistion of: "is there really life on other planets" the answer is most probably.

    It's kind of like the people who said that there was no life in the deep ocean. As large as the universe must be, it just seems hard to believe that Earth is really the only planet out there with life on it.

    We don't know at the moment for sure

    Well, how would you feel if I said:

    In the Pyramid Texts, it's written that Osiris ... meaning .....

    or

    In the The Bhagavad Gita, it's written that Krishna ... meaning .....

    Please, don't limit yourself by looking at things with "curiosity" in one hand and a "sacred book" in another. Explore all you can, no boundaries, you can think about anything with total freedom, possibilities with god, no god, many gods, dragons, UFO's are all alternatives until Science answers those questions.

    That can be discounted. No logical reason why only our rock has life.
    That's right. But remember, our galaxy has about 100 billions of star. All have not been explored. Secondly, planets are very much hard to detect due small size and low luminosity.

    Hindu scriptures talk of crores[ =10 million] of worlds.

    Any logical reason to discount it?

    But surely, if God was going to create life on Earth, wouldn't He have made sure it was intelligent life (which it manifestly isn't, given history as evidence)

    Which doesn't even say how those odds would shift if life occurred on THREE worlds in the same solar system.

    No. And no logical reason to accept it either. We're still limited by that sample size of one. (Which is why we should be actively seeking any life forms on Earth that aren't from the common ancestor. They might just be there. Lurking. Tiny, itsy bitsy things with different amino acids, or opposite chirality)

    Actually, we don't know what is causing the methane trace on Mars.It may have nothing to do with life. But I hope it is biogenic.
    Unless it turns out that life on Earth and on Mars are related, in which case we still only have one instance of abiogenesis. Life may have arisen once, on Earth or Mars, or elsewhere in the system, then transferred from one planet to another by lithopanspermia(that is inside an ejected meteor).

    If we find that there has only been one case of abiogenesis in our system, we can still say nothing about the frequency of abiogenesis in other planetary systems.

    Has anybody wondered why extra-terrestrials haven't contacted US?

    If you were a member of an advanced and civilised race, would you come here? If we did not attack them, between isolating them for the rest of their life, torturing them for their knowledge and dissecting them, it would be the equivalent of a modern man going to visit a tribe of cave men.

    Massive clouds of it have been released and mainly in the summer months.

    Maybe, like us they aren't advanced enough to do so.

    If "aliens" were that advanced, would they not have some way to be impervious to our savage ways?

    Extraterrestrials are ahead of us, both technically and morally. One of the awakened humans that has been amongst extraterrestrials is V.M. Rabolu. His book "Hercolubus or Red Planet" is sent for free upon request. Have a look at hercolubus.tv , you can request the book where extraterrestrial life is explained from direct experience.

    Extra terrestrials have not been shown to exist.

    Which would make this speculation.

    "Awakened human"? You means he's not asleep in bed?

    If he says he's done it then he's either mistaken or lying.

    That's nice, I wouldn't want to pay good money for junk.

    From delusion or invention, not direct experience.

    everyone always thinks about some high, supernatural being when they think about life on other planets. It doesnt have to mean that, all it could mean is there some type, even if its only a single-celled organism, on some other planet. If that is 100% true, then its already set a further step in finding out if there are more complex beings out there. The odds might be small, even for single celled organisms to thrive on a planet, but considering there are a countless number of stars in our known universe (considering its impossible to count the number of stars just in our galaxy in a lifetime if you were counting 1 per millisecond), which is nowhere near what our actual universe may be, the odds of someone else being out there become higher and higher.
    so for me, i think there are planets thriving with organisms somewhere out there, few of these planets may have intelligent, to extremely intelligent, creatures, but i still believe there is some planet out there somewhere containing highly intelligent creatures, and as for just life on other planets... im 100% sure there are.

    I really don't think so. Indeed in dozens of books, scores of articles and hundreds of internet discussions on the topic I can't recall anyone expressing that view.
    But that is a belief based on faith rather than science.
