    Why do more than half of the humans believe in God but not Aliens when the probability of the later existing is so much higher?

    First part of the paper:

    Are humans unique and alone in the vast universe? This question--summed up in the famous Drake equation--has for a half-century been one of the most intractable and uncertain in science.

    But a new paper shows that the recent discoveries of exoplanets combined with a broader approach to the question makes it possible to assign a new empirically valid probability to whether any other advanced technological civilizations have ever existed.

    And it shows that unless the odds of advanced life evolving on a habitable planet are astonishingly low, then human kind is not the universe’s first technological, or advanced, civilization.

    The paper, published in Astrobiology, also shows for the first time just what “pessimism” or “optimism” mean when it comes to estimating the likelihood of advanced extraterrestrial life.

    “The question of whether advanced civilizations exist elsewhere in the universe has always been vexed with three large uncertainties in the Drake equation,” said Adam Frank, professor of physics and astronomy at the University of Rochester and co-author of the paper. “We’ve known for a long time approximately how many stars exist. We didn’t know how many of those stars had planets that could potentially harbor life, how often life might evolve and lead to intelligent beings, and how long any civilizations might last before becoming extinct.”

    Personally, I think we're alone now.

    There doesn't seem to be anyone around.

    It is very unlikely that we are alone. The odds simply are stacked for life existing somewhere else.

    Earth is extremely rare of a planet with many many crazy conditions that had to happen. Including the spin, the need for the moon, the right gravity, the right make up of elements and radioactive metals, and the list goes on and on.

    But considering they are 200 billion galaxies. not stars. GALAXIES. Considering there are galaxies with a 100 trillion stars and the estimate of the total stars in the universe is 1x10^24 starts (that's a 1 with 24 0's after it). And that's just the observable universe - no one know how big the universe is - it could be infinity.

    To me, there is definitely advanced life out there - and it's highly likely to be made of DNA or a very similar molecule as well as proteins as these are fundamental construct of the top elements found in the universe.

    It's not a question of if there is life out there - it's a question of how far. Chances are, that life form and us will never find one another unless faster-than-light travel comes to be.

    There are certainly plenty of mysterious evidences here on earth that could mean Aliens existed on this planet before. We are so technologically backward as a specie in the grand scheme of things that we have no idea what is out there just like the cavemen have no idea that earth is round or there are other continents on earth.

    Don't worry, warp engine will be created in 2063.

    I read some interesting articles about the possibility (actually probability) that life exists out there.

    1. The conditions to support life might not be as rare as originally thought in the Universe.
    2. Other life might have been formed as non-carbon based meaning that you could exponentially expand the amount of planets that support life.
    3. In our own solar system, it appears the Mars might have once had some form of life (no definitive, but possible).

    If two planets in one solar system could have life, perhaps life isn't all that rare at all.


    So life existing out there somewhere isn't just possible, it is actually likely.

    Now will we ever come in contact with other intelligent life? Perhaps...but like Stephen Hawking said: We would never want to meet them. If they were advanced enough to reach us, they may only see us like a bunch of bugs. Plus, the likelihood that they share any type of morals with us is small. Interesting position from Hawking. http://www.space.com/29999-stephen-hawking-intelligent-alien-life-danger.html

    Size and time is so unbelievable large while human being and earth is so unbelievable small that it seems if there are trillions of alien life, we likely won't ever know.

    we might not ever see extraterrestrials , but They are out there.

    We are almost certainly not alone. Matter exists beyond our realm. But alien "life" may not even be observable or noticed even if it was right under our feet. They could be the size of particles. They could be inanimate rock formations who communicate only via telepathy. They could be giant balls of gas with billion year lifespans like stars.

    Who is to say they aren't "alive" because they don't breathe or bleed. The faulty expectation for alien life is that they closely resemble humans in matter and behavior. That probability is extremely small if you ask me.

    It's mathematically impossible that we are alone in the universe.
