    ^^^:tup::tup:

    I have'nt noticed any UFOs :rolleyes2::rolleyes2:

    BTW I too believe the very existence of biological extraterrestrials


    because there is life in exteme conditions of earth like

    In the water, scientists found species of bacteria that split hydrogen sulfide from the water to get energy to make organic compounds (chemosynthesis). The tubeworms have bacteria in their tissues that help them derive energy from the water. The clams feed on the bacteria, and the crabs feed on the tubeworms.

    The discovery of hydrothermal-vent communities showed that it is possible for life to evolve in places without light from the sun, and in other worlds without sufficient light from the parent star. In view of the discovery of hydrothermal vents, it may be possible that life exists on Europa, an icy moon of Jupiter, which scientists believe has a water ocean beneath its icy crust.


    Life has been found in other extreme environments as well. Scientists discovered microcolonies of lichens called cryptoendoliths in rock samples of the Antarctic desert, where temperatures often drop to 100 degrees below zero and there is little or no liquid water. In contrast, thermophilic (heat-loving) bacteria have been found in hot springs where temperatures exceed the boiling point of water.

    If life can evolve in extreme environments on Earth, it seems possible that life may exist in the extreme environments of other worlds such as Mars.

    Evolution on different world might certainly take different courses, but for species that may have reached the capacity of civilization necessary to produce space-fairing technology, just as humans have, there may be some common attributes selected for.
    First, would be intelligence.
    Next, would be the ability to systematically eliminate competition and impediments to the species's propagation, to some degree, not unlike humans.

    So we must be weary. If alien life is a statistical certainty in our universe, then doubtlessly there lies an extremely significant potential that among the possible space-fairing civilizations are 'super predator' civilizations, for whom traits as expansionism and systematic elimination of rivals were selected for, and contributed to their success over competing life-forms on their home world.

    The fact that aliens may have taken extra precaution to cloak themselves from our attention thus far given further credence to this theory; why hide, unless there's something to remain hidden from?

    Right now, humanity is a "space-fairing" civilization in the loosest sense of the word, so we are certainly not a threat.

    But given the potential for super-predator civilizations, I believe there is yet another reason for humanity to continue R&D and stockpiling with respect to its space-warfare capability, as well as WMD programs. The demilitarization of space may, in the long-run, work against humanity to this effect.

    I think most civilizations have such powerful Giants, and for some reason I do not think Stonehenge was actually laid by "human sized" people. But to take it then on human scale, Stonehenge and Pyramids took almost similar level of efforts (considering the apparent knowledge of their respective civilizations when building their respective models"

    1) There are 8,74 million species of animals on Earth; unless Milky Way galaxy is part of Earth (and I always believed it to be the opposite), there is no way there are only 400.000 species of animals in the Milky Way.
    2) Nazi war machine was NOT 25 years ahead of rest of the world in the 1940s. Their tank designes were 10 years behind rest of the world in the 1940, only taking a leap after invasion of France to produce awesome-but-useless Tiger I and awesome-but-only-somewhat-useful Panther by the 1942 - objectively best German tank design was Panzer IV Ausf. J; fighter aircraft designs through the war were about as advanced as these of Allied powers (UK had jet fighter design that was ready to fly by 1946 which was far more advanced than the Me-262), submarine designs were, up to 1944, essentially no better than those of World War I, main infantry weapon - Kar98 rifle - was designed in 1898 and used in World War I; they did produce assault rifle, but it was only in 1943-1944...

    So basically, Mahabharata is wrong and the second quote is pure BS.

    Greek civilization also had legends of heroes with superhuman strength, so did many others... in reality, there were no such heroes and "superhuman" this and that were used to justify rule of minority. Descended from Gods, so they have to be worshipped as Gods... no better way to prevent social revolution.

    Unless they used telekinesis.

    Evolution of life =/= evolution of sapient life. And if you want to search for life in other worlds of Solar system, Europa (the moon) should be place to start.

    There are Billions of Planets and stars and there is huge possibility that a ecosystem can exists which can nurture humanoid life forms... We are not even able to get off to Mars or out of our solar system. There is no point in wondering about the existence of Alien life forms now, First we have to get our foot up the ladder then we can gauge how much steps we have to travel.

    Simple fact is that once we get off with these petty politics in world then we can aspire of being a space exploring race. I wonder by the time we explore the other planets we might destroy our own in due course of time.

    Or maybe we have evolved into the size that we are (earlier people our size might be midgets)
    The problem of evolution is that say a man who is twice normal human size (height and weight) would be powerful but then if he is an hunter gatherer, he has to ensure that he has tremendous supply of food. Because the body twice our size will use 4 times the energy, thus running will be fast but then it would have to be a fast successful sprint. Or on other hand his system has to be designed (developed) in such way as to have a better efficiency rate of digestion and tranformation of food to energy,

    The advantage of smaller animals (example ant etc) they can carry many times their own weight, but as the animals become bigger, the percentage of weight (based on their own weight) they can carry reduces drastically.

    Yes, it's a square-cube law... muscle strength is dependant on its cross section, so if person is twice as large in all three dimensions its muscles will be four times as strong, but person will weight eight times as much. If person is half the size, its muscles will be 25% as strong, but person will weight 12,5% as much.

    Why do we think that it would be humanoids or carbon based life forms we might encounter in the future. We are very much limited with our search capabilities as we are trying to find typical organic carbon based lifeforms.
