Life outside of Earth. We are NOT alone.

This thread is a direct arguement to the "we are alone" thread currently on the main page by 'RevelationGeneration'. A post that shows a video of some Christian(I'm assuming, due to the 'God is the only other thing out there' comment at the end), claiming that our planet is the only one in the entire universe that can sustain life. I strongly disagree and for two reasons. Overwhelming evidence to the contrary and common sense.

Our galaxy is one of THOUSANDS of others. Our two farthest manmade objects are Voyager 1 at 109 AU from the sun and Voyager 2 at about 88 AU from the sun. I don't think we've sent anything outside of our solar system(If we have let me know). Abelle1865 is a galaxy 13.2 BILLION light years away. That is the furthest we have proof of, a picture, which was taken by Hubble. That means there are probably galaxies passed Abelle1865 which we haven't discovered yet.

This is the picture of the numerous galaxies. Not sure which one is the Milky Way, but take your pick then try and count the rest of them. To say there is no life elsewhere in the entire universe is silly to me considering we do not have the technology to even reach another galaxy with our probes. It's just something close minded people hear from our government(which never lies, right?), and assume it's true.

People ask for proof that they have visited Earth and use the "lack" of it as proof that they DON'T exist. Well I say maybe we have proof but people choose to ignore it. Let's take a look at a few examples.
www.examiner.com...=31444531 These are artifacts and cave paintings depicting aliens or astronauts.
channelingmyself.com... Here are a few more. Also included are a few pictures from the Renaissance era. If you google search 'ufo in art' you will be overwhelmed by the amount of paintings have depictions of UFOs.

I can go on and on with "proof" that can debated either way. As to not make this thread a monster to read I will skip the rest of this part and go right to the "common sense" part of my reply to said thread.
"The U.S. government has no evidence that any life exists outside our planet, or that an extraterrestrial presence has contacted or engaged any member of the human race," Phil Larson from the White House Office of Science and Technology Policy reported on the WhiteHouse.gov website."In addition, there is no credible information to suggest that any evidence is being hidden from the public’s eye."

This is the very first quote in the thread. Obviously I had a good laugh as soon as I read the first sentence. No life exists outside of our planet? Is bacteria not life?
www.scienceagogo.com...
"space" bacteria has been falling into our atmosphere and has been proven.

www.geek.com...
DNA and RNA has been found on meterorites. Amino acids... the building blocks of life.
articles.cnn.com...:TECH
If you haven't heard about this yet it's the "red rain" that fell in Kerala in 2001. Samples indicate that it holds microbes from outer space.

I think that's all I'll write for now. Not to offend anyone, but in my opinion only a fool would believe that humans are the most advanced civilization in the entire universe. Just because we're not visited regularly and shaking hands with E.T. or the alien from American Dad doesn't mean we're alone.
Keep an open mind.
-Athin

200,000,000,000 - 600,000,000,000 is around the number of stars in our galaxy.

There are around 50,000,000,000 planets in our galaxy. About 500,000,000 are in the habitable zone of their star.

There are about 200,000,000,000 galaxies in the observable universe.

200,000,000,000 x 500,000,000 = 10,000,000,000,000,000,000,000 estimated planets in our universe in the habitable zone of their stars.

If you look at purely a mathematical perspective there is life in some form out there.

S&F

I Have already voiced my opinions in the other thread...

Summary though...

Thinking we are the only thing in the entire universe is the most arogant thing a human can do....

Its a way to avoid the fear of being just another something in a universe of things!!

I Will agree you cannot prove the exsistance of actual life in the universe outwith our own (except fossils of basteria, but we all know where the religous nuts stand on fossils) any argument put towards Extraterrestrial life not exsisting can have the words Extraterrestrial Replaced with God and Angles and the same sentence can hold true...

If you get offended when people say your beliefs ar Wacky and wrong and laughable do not do the same to others...


OOOh and hells not real

Nonsense. Just because you find a marble in a box, and you have no idea how it got there, doesn't mean that if you get 100 billion more boxes, there is guaranteed to be another marble in at least one of them. Unless you can show how life happened, you can't logically say that more of anything is going to guarantee life will happen again.

As for the old "arrogance" notion, I don't see how it can be arrogant to suggest that Earth might be the only planet with life on it. How does that make us better in any way? If anything, it makes all our activities here from the beginning of time completely pointless and unheralded. If there's nobody else out there, who cares? Nobody. That is pretty much the opposite of arrogance.

There is too much 'evidence' out there to say we are alone. The reason I put evidence in quotes is because a lot of it is conjecture. But as the old saying goes, 'where there's smoke, there's fire.' Too many things have happened throughout history to discount them so easily.

The battle of Los Angeles, the Nuremburg incident, Betty and Barney Hill, Travis Walton, the countless other abduction stories, the story of the man who was raped by alien women and had pubic hair evidence, cave drawings of people in space suits and flying machines, ancient religious texts about flying machines in which 'God' resided, cattle mutilations, crop circles, just to name a few.

The information is there, and some are too blind or stupid to see it. They'll probably say it's God when a flying saucer lands in their back yard. Some people can't be helped.

Maybe you did not read the entire thread. Life has ALREADY BEEN FOUND outside of our planet.

A 2001 experiment led by Jason Dworkin subjected a frozen mixture of water, methanol, ammonia and carbon monoxide to UV radiation, mimicking conditions found in an extraterrestrial environment. This combination yielded large amounts of organic material that self-organised to form bubbles or micelles when immersed in water. Dworkin considered these bubbles to resemble cell membranes that enclose and concentrate the chemistry of life, separating their interior from the outside world.

In 2009 it was announced by NASA that scientists had identified one of the fundamental chemical building blocks of life in a comet for the first time: glycine, an amino acid, was detected in the material ejected from Comet Wild-2 in 2004 and grabbed by NASA's Stardust probe.

Then there's the "Soup" theory.

Basically, we have a somewhat decent understanding of several ways that life could have started on Earth.

Yes except thats not how it percieved,

it is viewed in a religous context by most religous people that we are unique creations of God, as opposed to how i percieve it another lump of bacteria that had the right amount of time, oxygen water and daylight to grow some legs, thumbs and get a job!!


See from what i beleave bacteria from asteroids from somewhere in space landed on earth and so began a cycle of evolution which eventually after many changes in atmospheric gases and tempetures on earth evolved into many species at the most advanced (that has survived to this day currently) on Earth being human..

As this is what i think i find the idea of bacteria not landing on one or millions of the billions of planets avaialble and evolving in a way to suit the planet in question is incredibly ridiculous...

now most religous people come on a religous thread and state that God by fact did X,Y and Z because of what they beleave without any proff and anyone who doesnt beleave this is arogant, childish or going to hell etc..

i am perfectly withinn my own right sdue to my explained belifes to find anyone who thinks we are alone in the universe to be arrogant, am i not?

Wrong. Do your research. If ET life had ever been absolutely confirmed and verified, you would have seen it on every news source in the world. All we have so far is conjecture, possible evidence, and theories.

we feel so alone, on a planet of 7billion, in a universe of x amount of stars and planets.
so cutoff. so isolated. even from ourselves.

This was on the news.

Comets also contain a variety of organic compounds; in addition to the gases already mentioned, these may include methanol, hydrogen cyanide, formaldehyde, ethanol and ethane, and perhaps more complex molecules such as long-chain hydrocarbons and amino acids. In 2009, it was confirmed that the amino acid glycine had been found in the comet dust recovered by NASA's Stardust mission. In August 2011, a report, based on NASA studies with meteorites found on Earth, was published suggesting DNA and RNA components (adenine, guanine and related organic molecules) may have been formed on asteroids and comets in outer space.

Human beings cannot be made with guanine and adenine. Just fyi.

So you have bubbles, and the "building blocks" of life. But where's the life? How do they get together and start thinking and having a point of view? Is it random? How random? Is it possible that it might only happen once, ever? There are singular, unique things in the universe, you know.

Like yourself. The odds of things happening in such a way as to bring you into existence are probably not that much more than a bunch of chemicals all falling together in such a way as to create a living, thinking, reproducing organism. Is there another you out there in the universe? How many? After all, the "building blocks" are everywhere. How many other "yous" are there?

Uh, the life is all around you. They didn't start thinking until complex organisms came about. Single-cells lack a brain. Is it random? No. It is replicable in a lab. So by my standards, not random. What is singular in the universe? I know of nothing, the universe isn't even singular. It is now accepted by the majority of the scientific community there are more universes. And who is to say these are the ONLY chemicals to make life? Perhaps creatures can be made from arsenic and sulfur on another world. In fact, mono lake holds some organisms that survive on arsenic.

So? Were these things alive, or once alive? No. Here's an experiment for you. Rather than just some bits of amino acids, get some long strands of actual DNA (it's not that difficult), and put them in a beaker and start shaking it. Let me know when it coalesces into a living organism with a point of view and can reproduce itself.

You can have all the parts you want, but that doesn't make it alive. Just like you can take all the parts of a computer and put them in a bag and shake them for 13 billion years, and you're not necessarily going to ever end up with a fully-functioning computer.

The truth is, we only have one example of a planet with life on it -- Earth -- and nobody (even the religious among us) knows how life came to be on that planet. Without knowing that, it's not possible to determine the odds of life ever happening again anywhere, and maybe not even then.

i agree with you final sentence.. however we have looked at like 00000000.1% of the possible planets for life as we designate a possible planet for life which bases our biology and physics! then you have the fact we have looked for life that would be transmitting or using technology as we do, so yes i will give you we can only use earth as an example but it is exactly like me looking out my window to my back garden and saying there is no plants on earth because in my back garden you can only see gravel!!

There have been plenty of experiments that show that even bacteria have an awareness of their existence, and preferences for food. You don't need a brain to experience and interact with the world and make it real, and plenty of single celled organisms are alive.

The question is, how did it happen? It's not simple chemistry. It's insanely complicated. How did all that stuff magically combine to suddenly become something that wants to eat and excrete and reproduce? The answer is, nobody knows. Sure, some parts naturally stick together because of the chemical reactions. But nobody has shown where or how they naturally stick together to become a living thing.

Our life on Earth could be a literally astronomical fluke. Something that could never happen again if the universe lasted forever. We don't know. And that's why we can't say for sure that just because of the number of worlds and the size of the universe that there positively absolutely is life out there somewhere.

Read this page. It's pretty lengthy but it should give you various 'acceptable' answers to your question. I would summarize all of the different parts but I'm slightly lazy today.

While I'm not going to argue over single-celled organisms and what not I will tell you this. If you take the salmonella virus and put it into space, it because over 100x reproductive and deadly. NASA has put several viruses into space and almost all of them thrived. Just food for thought.

That's not the same analogy. It would be more like me looking out the window into the back garden and seeing a diamond the size of a car there, and without knowing how it got there assuming there must be a similar diamond in many, many other back gardens because there's one in mine and the conditions in the other gardens are essentially the same.

It makes me think that thanks to NASA, any ET life we know about originated on Earth.
