Topic: Apparently, aliens do exist.

maybe these alleged 'aliens' don't need what humans call sustainable life to live ;3

The only "life" that exists on other planets is most likely just bacteria or mico-organisms. But since there is no definitive proof that there is or isn't life out there you can'r prove it wrong or right. Until we have some solid proof, I'm going to believe that we're probably alone in the universe, but I'm open to believing in aliens, if you have the proof to back up your theory... and this article is not a theory its bacteria they found on a lump of rock.

Does anybody really doubt that life exists elsewhere in the universe? Intelligent life is something else, but it doesn't make any sense that there wouldn't be life elsewhere

I doubt! I really do doubt actually. For what I believe, it wouldn't be likely, or that fair for life to exist on other planets. Either that, ot it doesn't really matter for us anyway so we shouldn't worry about it.

Then they'll burn up from radiation, or freeze and crumble into dust particles before they're ever born.
There's also one other thing we have that they don't, proof we exist, and that's all that matters.

definitive irrefutable proof of an other worldy being right there.

Of course Aliens exist. I'm sure they look nothing like what is depicted on TV and in movies but I refuse to believe there's no other living beings in this vast universe. It would be pretty narrow minded of us to think we're the only life out there.
It's probably best we don't find out though. Too many of us fear what we don't understand.
Remember what Yoda said... Fear leads to anger, Anger leads to hate and hate leads to suffering.

I'm a pessimist regarding issues like this. I admit that there is almost certainly some forms of life closer than we think, but not so certain about intelligent life (and I remain adamant that we haven't had contact with any yet).

Assuming said life is carbon based.

Exactly my point ^

I love how some people take the "If you don't believe in aliens, you're close-minded" approach.
Facts, without them you cannot prove an event happened, or that something was somewhere.

Now don't twist this into a "If you can't prove it doesn't exist, then it does!" because it doesn't work like that. That's like me saying "I can fly at will", and when you say "Prove it", and I say no, should you still believe me? No, that would make you an idiot.

The first claim of alien life has never had the facts to back it up, and through science, we've shown why every other planet that's apart of the 22B stars we've seen cannot sustain life. We're just incredibly lucky that our planet is in JUST the right distance from our sun to provide the right atmosphere (Like an O-zone), with enough heat to keep us warm, but not boil our water, and be cold enough to keep the planet cool and not overheat, but without being too cold to not allow water to form.
It's such an exact formula that it's no wonder we have not found another Earth. We've found similiar planets for sure, but not exact, and in order for a formula to work, it has to be precise.
/rant over

Who's to say we're not the only life forms? We're probably just one of thousands. If we were created and/or evolved into what we are now, humans, then somewhere else there is bound some species similar to us out there, there's just too much planets out there not too be.

@Bed: Yeah, lucky, that's it.

It's like gambling, there's 4 cards upside down, only one of them is the Ace of Spades, and that's your money card. So the dealer shuffles the four cards around out of your line of sight, and you have to choose which one it is.
Statistics say you have a 25% chance, so your brain automatically tells you "Play 4 times, and you'll win" because 25X4=100. But logically, we all know that you can end up never getting that Ace of Spades (Not because the dealer has cheated,mind you ), but because it's 25% every single time you take another shot.

It's the same with this topic of habitable planets. Just because there's billions of planets, it does NOT mean just because one of them supports life, that it can (Or as you might say, WILL) support life. The chances are far worse then 25%, hell, it's even lower then 0.0000000000001% , so what makes you think you can get the Ace of Spades now?

@zez - Don't you dare bring religion into this, haha.

I haven't read the article yet but I doubt this is true. A couple months ago, scientists had supposedly found bacterium that incorporated arsenic into its DNA. Turns out that was wrong. And that was published in one of the most prestigious journals Science. The Journal of Cosmology doesn't exactly inspire as much confidence.

Personally, I don't believe there is alien life out there. But that can never be proven...

Considering the history of the cosmos, that our planet would sustain life is improbable.

Considering the size of the cosmos, that another planet would sustain life, by our or any other definition, is nearly inevitable.

There's intelligent life in the universe. It's just not on Earth.

Well, technically it's possible for things with a different biochemistry to be out there. Like instead of water, their planet would have seas of ammonia, and they'd be silicon-based. For example. It's not that far-fetched
And they don't have proof that we exist

You don't need to tell me. I have a blue alien chick in my closet in a special underground facility that studies aliens.

And I have studied her oh-so-extensively, ehe.

Makes me wish I was a blue alien chick.

It is possible that we could find evidence of life on one of Jupiter`s moons (Europa? I cannot remember which) underneath its icy outer layer. If the moon is active enough, there could be liquid water. Other than that, there is the astronomically small chance of life coming from an asteroid.
The closest solar system is just too far away for life to come to us or vice-versa.
