    7:32 Seeking for advanced alien civilizations/ Well, don’t we have enough
    UFOs around here that we need to go elsewhere to find them? I don’t
    understand. They’re floating around in ORBS, ufos, aliens walking around
    and yet we’re still sending messages to outer space LOOKING for them?? Well
    either all the ufo vids are fake or no one is listening… they’re
    exploring our skies… find a way to communicate with them, gosh!

    I’ll be conservative and guess that a civilization produces Detectable
    Electromagnetic Radiation for a period of only 100 years of its history.
    But even with that narrow period, considering the numbers, and considering
    the proportion searched so far, we should have found someone. We haven’t.
    This means either we haven’t searched enough yet, or Something Else. The
    Something Else is now becoming more and more likely.
    One Something Else is that we are actively being prevented form seeing that
    there are other civilizations. Perhaps we are in a zoo where our keepers
    want us to believe we are in the wild.

    I read the book Rare Earth. The N^ Equation called the Drake equation is
    old given the scientific advances in cosmology and his theory.

    The point they make. It’s not about location, how many are earth like or
    resources of elements. You need things to happen at a certain time, at the
    right time and on the right amounts and that window is very small. Its one
    reason we don’t see the process anymore. It was very brief and to the point
    with no waste.

    What I found funny was they screamed the scientist were creationist as if
    that was a rational argument. Given we all believe in creation in someway
    or were not around.

    I can’t believe how unimaginative some people are. Yes, that biologist is
    correct, but how does he know for sure, that life didn’t come to Earth from
    elsewhere. This ancestor that shares the same type of face as ours, 2 eyes,
    2 ears, a nose, and a mouth, could have come from somewhere else. Like 1 of
    the comments before mine reads “we are the aliens,” just like the movie
    Prometheus. Is that not a possibility? Also, why does life elsewhere have
    to follow Earth’s rules? Perhaps life is more adaptive that we think it is.
    Until we find life elsewhere, or life elsewhere finds us, I think we should
    be open to the unexpected. Outer space is so vast, and the Milky Way is the
    only galaxy, and we could be living in a multiverse reality. Do the rules
    on Earth, or in the Milky Way, have to apply in other planets, galaxies,
    universes, or alternate realities? I say not necessarily. I know I’m
    blurring the line between Science, & Sci-fi, but those lines have always
    crossed paths.

    I love that some thing yet to be proven scientist speak on terms that they
    only know which is Earth biology. Millions of galaxies with trillions of
    stars and it all has to be based on Earth biology or as one guy stated that
    they wouldn’t because that would mean they have Earth traces of biology.
    Maybe we have their trace DNA but either way until we meet E.T its all

    Ufos are fallen angels and there among us since we where created. They’re
    teaching this technology advances hi there just lying to us they’re not
    telling us the truth. Don’t you think its weird that we just all of a
    sudden came out with advantages of technology from just one century
    humanitiesby are self wouldn’t have done by are selfs we had help.

    @Nehmo Sergheyev
    quite the opposite actually…
    considering the numbers; we’ve searched for barely a quarter of the
    century, on <1% of the available range in <1 % of the potential individual
    radio bands (yep: we only recently tapped "space broadband", lol)...
    ..Of course, the decades we have searched may seem like significant
    coverage considering the speed of radio waves(light=C). However, this only
    allows for a radio influence, or "sphere" of coverage, with a diameter
    which permeates only the immediate star systems within our local
    [star]cluster, within our [theoretical]arm of the Milky Way...
    ...Therefore, the only "failure" in the search programs is applied
    technological constraints and the unfathomed size of the universe on our
    scale; or in absolute terms...
    ...Time and Money. lol

    Totally agree….the advanced alien civilizations have already found us!!
    By a factor of thousands of years! Head in the sand type of exploration as
    practiced by telescopic star-gazers discards completely, the veritable
    mountain of video and verbal evidence accumulated over the past 60 years,
    supported by hundreds of highly qualified people from all walks of life.
    Take your head out of the ground and open your eyes….and your
    mind—Their here!

    Convergent evolution describes the independent evolution of similar
    features in species of different lineages. Look it up Neil.

    Alliens don’t need to be like us, they don’t need a planet like earth, They
    might be in the form of Steel or fire, Take example of Transformer movie,
    Maybe they look like that, There is many thing we don’t know

    Ha Ha…your are all crazy. There are no aliens. God creates humans and
    animals on earth. There is nothing else. Read the Bible.

    All the ‘Aliens’ that have ever been seen on earth are in fact from the
    Spirit world!
    Revelations 12:
    7 And war broke out in heaven: Mi′cha·el and his angels battled with the
    dragon, and the dragon and its angels battled 8 but it did not prevail,
    neither was a place found for them any longer in heaven. 9 So down the
    great dragon was hurled, the original serpent, the one called Devil and
    Satan, who is misleading the entire inhabited earth;

    We are all aliens, we are here on earth for a very short time, then another
    intelligent life form will evolve. All this is happening while other life
    forms thru out the universe do the same thing. We are all aliens.

    The real challenge is to find intelligent life just here on Earth. SETI
    should stand for “Search for Earth Terrestrial Intelligence” indeed.

    I really like to imagine a planet with dinosaurs that didn’t get hit by
    killer rock and was allowed to evolve into even smarter beings than mammals
    ever did. Also, plant life and sea life. Maybe the most intelligent
    creature in our galaxy is more like a cuttlefish or a mushroom.
