Aliens? (the ones that aren't from Earth)

[cubsfan6506]

Won't be anything taht we recognize as intelligent. The odds of them being bipedal and haveing a similar thought process are so unlikely.

 

[Eran of Arcadia]

What does bipedalism have to do with intelligence?

 

[SG-17]

They do exist on a multi-cellular level, and with some sentient species out there.
It is impossible that we are alone, and if you think we are, you must have been hiding under a rock from 8 thousand years.

Anywhere there is carbon, or silicon, and water life can form. There may be other elements that life can come from, and some may not need water, but as far as we know, there has to be one of the two and water.

Most peoples fantasies about aliens are bipedal. It should of been to sentances. On a further note I also view the development of the eukaryotik cell as a rare occurence.

Suuuuure.... And it's impossible that from almost 7 billion* humans in the world, none has exactly my fingerprints, and if you think there isn't someone out there to have exactly my fingerprints, you must have been hiding under a rock from 8 thousands years. FYI, there are only 264 extra-solar planets discovered.

*7 billion humans in the world = 7,000,000,000 humans in the world. And none of those has my fingerprints (I do know we didn't reach 7 billion yet, but we're well over 6 billion).
Exactly 272 planets discovered by November 2007.


Don't you understand that, for something for which there is no evidence, you need to PROVE its existence to convince people to accept it, not to DISPROVE its existence to convince people to not accept it?

 

[BirraImperial]

They probably exist, we just haven't made any contact with them yet. I find it very unlikely that we are alone, I mean, just look at how big the universe is.

And several of them deemed capable of life, by the size and distance from their star.
There is plenty of proof, but most of it is eye-witness accounts, photos, and videos.
And the odds of our planet being the only one with life in the galaxy is like one in several billion/possibly trillion, and in the entire universe one in near infinite.
Not to mention the Drake Equation.

Yes, but how many planets are out there?

Life can occur in a variety of ways, not only the ways that it occurs here on Earth. Scientists are continually amazed as they find life in new places, surviving in ways and off of things they never thought possible. Miles under the ocean, for example, you find life feeding off of thermal vents. They have a completely different system for processing nutrients than other sea life. Or bacteria in the frozen wastes of the poles, again, where scientists never thought it possible for life to be sustained. Your comparison to fingerprints makes no sense in this discussion.

 

[Trafalgar]

Show me an alien and I will believe in them.

 

[mdwh]

For those of you who think there MUST be intelligent life simply because there are so many stars, so many planets, etc read up on Fermi's Paradox. Basically it says that if intelligent life has existed elsewhere then even a very slow expansion rate would mean that that life and signs of that life would spread across the galaxy in a short amount of time(in galactic sense). But if this is the case, why haven't we discovered it?

The same article also lists plenty of possible explanations though...

For God's sake - if the universe is infinite it doesn't mean that the chance of life to exist is 1! Because an infinite universe does not equal an universe where everything exists. That belief comes from some people's inability to understand the notion of infinity.

Do you also believe there must be some Mona Lisa paintings in the outer space?

The "infinity" argument is simply void! Do you agree with me that since the universe is infinite, the space between all particles in the universe is also infinite? So, there must be life in the space between all the existing particles, because it's infinite, so what are the odds of it not happening! That's how this logic goes!

There is plenty of proof, but most of it is eye-witness accounts, photos, and videos.

So you believe aliens not only exist, but they are here already, seen and recognized but only by some people, just not by the opaque masses. Right?

Vulcan.........
I said that the chance on Earth being the only planet with life to be one in a billion/trillion.
Well there are Mona Lisa paintings in space, we have been broadcasting video and audio signals into space, and I've seen the Mona Lisa plenty of times on over-the-air broadcasts.
Maybe I over exaggerated a bit with the universal chance.

So you believe aliens not only exist, but they are here already, seen and recognized but only by some people, just not by the opaque masses. Right?

Well our planet is young, only 4 billion years, while the universe was created around 13 billion years ago, while as we have seen with Mars it only take about 3 billion years for a planet to have life sustaining abilities(to what we would call life). So there is most likely a planet which was created more than 8 or so billions years ago, that retained its life sustaining abilities, and developed a sentient species who would of had a several billion/million head start on us and most likely has harnessed some type of FTL travel, whether it be through wormholes or whatnot. So yes, I do believe they have visited Earth.

None of which satisfy me.

 

[bhsup]

Here is the thing. Out of the whole of God's creation, I seriously doubt he graced only this one little mudball with life.

 

[Eran of Arcadia]

Yes, I also believe in life on other worlds for religious reasons, I should probably point out.

 

[Trafalgar]

I guess God would be an alien.

 

[Eukaryote]

The universe is like 100 Quadrillion lightyears across, so yeah, I expect there is.

 

[Masquerouge]

I think it is more likely than not that ET exist
I think it is more likely than not that we will never meet them.

It makes me cry.

Dude, FTL has been pretty much ruled impossible. And the abiity to sustain life doesn't mean life. Certainly there are a large number of worlds in habitable zones of stars but we have no idea what the probability of a world in the habitable zone has of having life.

Why not?

No evidence, I'm not saying they don't exist just that there is no scientific basis either way.

Actually, because I'm a pragmatic investor. I'm thinking along lines of Pascal's Wager. Planning to eventually run into ET life will lead to a different gameplan than not. And the consequence of being wrong (either way) is lower (imho) my way.

That's kinda a crappy argument for believing we will eventually run into ET. What we should do is believe that we might but with uncertain probability.

Aliens?

No, sheep. And they sure taste good.
