    I'm not sure if you're joking but that's not how it works. Boiling point is a physical property that does not change with location.
    You are dead wrong there. The boiling point of water is 100 degrees C at 1000 millibars of atmospheric pressure, and it is zero degrees C at 0 millibars of atmospheric pressure. Increase the atmospheric pressure above 1000 millibars, then the boiling point goes correspondingly up. On a planet with more than 6 times the mass of earth, sea level pressure is going to be much, much higher than the sea level pressure on earth, hence the much, much higher boiling point.

    Nevermind, Wikipedia says I'm wrong.

    Gigantic. Crushing gravity. Searing heat. Earth-like.

    Please select the term that does not fit the pattern.

    Given the size of the universe, there is no way complex life forms do not exist elsewhere.

    Declarations concerning the impossibility of life are usually proven wrong, given enough time. Just because we can't possibly imagine how carbon-based lifeforms could develop at such relatively high pressures doesn't mean they can't form. And who says life must be carbon based? Speculations of life always remind me of this little gem:

    Each statement is relative, so I find a clear pattern.

    The fact that it is more earth-like than any previously found outside the solar system, and more earth-like than most planets in the solar system.

    Without knowing every variable, you can't possibly make such a statement. Speculations on life are exactly that, speculations and nothing more. Until life is actually discovered, the search is not falsifiable and therefore cannot be considered a science.

    Actually, I CAN make such a statement:

    Given the size of the universe, there is no way complex life forms do not exist elsewhere.

    See?

    Of course, I understand that my statement does not constitute proof of anything, but it is still logical, and mathematically very plausible.
