What scientists say:

1. 1976, The Viking Mars landers detect chemical signatures indicative of life

2. 1977, The unexplained extraterrestrial “Wow!” signal is detected by an Ohio State University radio telescope

3. 1996, Martian “fossils” are discovered in meteorite ALH80041 from Antarctica

4. 2001, A more rigorous estimate of the “Drake equation” suggests that our galaxy may contain hundreds of thousands of life-bearing planets

5. 2001, The red tinge of Jupiter’s moon Europa proposed to be due to frozen bits of bacteria, which also helps explain the mysterious infrared signal it gives off

6. 2002, Russian scientists argue that a mysterious radiation-proof microbe may have evolved on Mars

7. 2002, Chemical hints of life are found in old data from Venus probes and landers. Could microbes exist in Venusian clouds?

8. 2003, Sulphur traces on Jupiter’s moon Europa may be the waste products of underground bacterial colonies

9. 2004, Methane in the Martian atmosphere hints at microbial metabolism

10. 2004, A mysterious radio signal is received by the SETI project on three occasions – from the same region of space

    It ould be a bigger suprise if life didn’t exist elsewhere

    We may just deserve and get, the surprise of our evolution.

    Typically reasonable of our species was the decision to allow everyone to vote on a decision that involved broadcasting to the Cosmos who we were, our technical abilities and where we could be found.

    2010, The volcanic ash clouds over our skies block transmissions and aliens from the far reaches of the galaxy land on earth undetected.

    MTG,

    and since our technical abilities are almost zero..

    But that broadcast doesn’t matter, we already broadcast widely, via radio/TV waves, etc. currently over 100 light-years.

    And we insist on altering the local fabric via our increasing production of unstable elements, – clearly visible to those with the finesse, – that also speaks of our technical abilities.

    Dear XXXl

    I was always aware of our village takeaway but only developed an appetite after they dropped their menu through my letterbox……

    MTG,
    True

    But…

    We have SETI

    Everyone argues that, given the possible numbers of stars, let alone planets, it is inconceivable that we would be the only intelligent life form….you could equally argue against us being the only intelligent species to have a SETI.

    SETI operators don’t need a menu, they are already looking!

    Finding a nearby take-away is motivation to climb into the car!, or at least get on the ‘phone.

    Our planet is particularly nourishing because of our moon creating plate tectonics creating volcanic activity and mountain ranges that over millions of years thrust heavy minerals nearer to, or in fact, to, the surface. This is a fact only found on planets having moons of our nature…other planets, absent some adjacent body large enough to possess a gravitational field to create these movements, carry their minerals much nearer to the core.

    In my humble opinion the authorities that advertise our presence deliberately are fucking idiots.

    I also consider it pretty important that we develope some sort of masking technology for our celestial use of radio waves.

    I also consider it to be too late to mask, the word is out!

    You may argue that masking technologies already deployed are one of the reasons we have so far failed to locate other, more wise, species.

    Have a look at LLoyd Pie’s take on human evolution and it’s relationship to alleged alien influences.

    If he’s right, everything we know is wrong, and in fairness he makes a few telling arguments.

    Shall look.

    Just to avoid any hint of ambiguity.

    I mentioned above, masking our radio waves somehow, that have now been spreading for just over 100 years… that means a distance of 100 light years…. and that is the radius of a sphere wherein they have spread.

    My comments that is too late to mask radio waves related purely to this context, and did not relate to any other circumstances.

    We telegraph our moves.
