Mars has water, what if it did/does have life?

    Dont start with the "microstructures strongly resembling bacteria."
    Or the "look like growing fungus" stuff. Everyone has heard all this but it proves nothing except for the fact we discovered things that resemble other things but are not the other things.

    Its just like the 'face' on Mars, proof of another civilization. Look at the recent pictures and its just a mountain.

    If they do find something alive or previously alive that would be great but they havn't and I don't think they will.

    There is always the possibility, even if slim, that the gamma ray scan of Mars is indicating hydrogen stored in some novel and unsuspected, non-water way.

    But water is where my heart is.

    I think the chances are better than even that we may find active lifeforms - bacteria - on Mars. The variety of life on earth, and the wide conditions under which such life is found, especially the older lifeforms, the archaeobacteria, that thrive in thermal vents that are strongly acidic. If we found evidence that life on Mars evolved to a higher level - starfish say, or coral, so much the better.

    Most of my money would go on Europa however. I think the circumstances of that moon practically scream "LIFE!"

    I've looked at Watchtower statements about such possibilities, and seems that they've left the door open for the possibility of lower extraterrestrial lifeforms, although they haven't offerred an explanation for how those lifeforms might have gotten off of earth.

    Maybe Jehovah accidentally dropped some seeds on his way back to Alcyone in the Pleiades.

    Okay, how do we arrive at this conclusion:

    unique mineral composition = came from Mars

    See, cuz I'm starting to see a kind of inspired-bible type of circular reasoning here.

    You can believe the bible. It has the truth in it.
    Why?
    It's God's word.
    How do we know?
    The bible says so.
    How do you know it's telling the truth?
    You can believe the bible. It has the truth in it.

    And so, we have...

    Did you know Mars may have bacterial life on it?
    How do we know?
    Meteorites from Mars have structures like bacteria in them.
    How do we know they're meteorites from Mars?
    Unique mineral composition.
    But we can't compare them with the composition of Mars. We don't have any samples from Mars for comparison.
    Sure we do. We have meteorites from Mars. Did you know Mars may have bacterial life on it?

    COMF asked how we know the meteorite is from Mars.

    Although this is not a detailed explanation, it may help. It's from Discovery.com. "All of the new meteorites are thought to be from Mars because of their telltale peculiar iron-manganese and oxygen isotope compositions. These chemical signs tie the rocks to the first discovered Martian meteorites that contain small bubbles of Martian atmosphere — the surest sign that a meteorite is from Mars."

    One difference between science and religion is that science is willing to discard a hypothesis once it is shown to be false.

    cited:It was known as early as 1872 (Tschermak) that the
    Shergotty meteorite was a basalt that formed under
    relatively oxidizing conditions, but it wasn’t until 1979
    (Walker et al., Nyquist et al.) that it became apparent
    to meteoriticists that the relatively young SNC*
    meteorites may have come from the planet Mars. This
    hypothesis was explained in detail by Wood and
    Ashwal in 1981, but it wasn’t until Bogard and Johnson
    (1983) found gas trapped in glass in shergottite
    EETA79001 identical in composition to Martian
    atmosphere (as measured by Viking experiments), that
    it became widely accepted that SNC meteorites came
    from the planet Mars. Also in 1983, Clayton and
    Mayeda showed that SNC meteorites formed their own
    subgroup on an oxygen isotope diagram with their own
    fractionation line separate from that of the Earth or
    HED parent bodies. In 1984, Becker and Pepin found
    that nitrogen isotopes and N/Ar ratios were also typical
    of Viking results, clinching the argument (figure I-1).
    In 1995, Marti et al. found similar results in glass in a
    second SNC meteorite (Zagami).
    Briefly, Martian meteorites are igneous rocks (basalts
    and cumulates) that have been shocked to various
    degree. However, they are not badly brecciated. Table
    I-1 gives the modal mineralogy. All, accept one
    (ALH84001), have young igneous ages. They were
    apparently blasted off Mars over the last 16 million
    years, judging from their cosmic-ray exposure ages.
    Several were seen to fall and were collected, others
    were recovered from the ice in Antarctica.

    Thank you, gentlemen.

    There are obvious questions; for example, "why do we assume that the atmosphere of Mars 16,000,000 years ago was the same as that examined by the Viking experiments in 1976?" But I was asking out of idle curiosity. You've been generous with your time and effort, and I appreciate it.

    I'll research this further; my curiosity's up now. :)

    So true.........

    How would the writer acting as THE channel between man and God feel reading this now-

    Man cannot by airplane or rockets or other means get above the air envelope which is about our earthly globe...

    DOH!!!
