Poll: Do you believe that aliens exist?

[Renegade-pizza]

Just curious. I believe in the possibility of extraterrestrial life. In this crazy universe where suns explode and planets made of alcohol drift around(I'm dead serious). Who says that the building blocks of life haven't come together to form the most basic organism?

What's your view?

 

[LordFisheh]

I feel that there's almost no chance of alien life not existing. Saying that we're the only living things in existence anywhere smacks of the same arrogance that led us to assume that the sun revolved around the Earth, that God personally made us as a superior species (in his own image, naturally), and so on.

Though whether we'd even be able to recognize it as life in the first place is another question.

I believe there millions of different alien life forms in the universe but also that none of them have visited earth.

Took the words right out of my mouth. An infinitely expanding universe whose rate of expansion is increasing as it expands?

No matter how rare the conditions for life are, they'll be out there somewhere. Especially now that we know things can be based on, what was it, arsenic or something?

this post has been done a few times but either way its hard to believe they would not excist the galaxy is vast its very unlikely we are the only ones.

 

[Boris Goodenough]

Very much so, but I very much doubt they've been here.
Also, life is more likely to be a "one celled" organism than greys with hyperdrives.

 

[smithy_2045]

I see no reason to believe in their existence until some actual evidence exists to support it.

 

[Sovvolf]

I believe its highly possible however I have serious doubts that they have or do visit us or whether or not they actually have the technology to visit us.

"The absence of evidence is not the evidence of absence" -From somewhere..

Even if we scan every inch of our entire galaxy and prove without a doubt there's no alien life, that still leaves another 90 or so billion other galaxies which could. I assume they exist but haven't been found yet, but up until then I don't see why people can outright refuse to accept the possibility.

EDIT: I'm the only one so far who thinks they've visited? *puts on tin foil hat*

Aliens are fun to believe in, even a bit scary at times. But are a generally compelling phenomena.

I like to believe that aliens exist, but I've yet to see something personally that lends credence to that. I've seen lots of videos, lots of blurry and boring ones, lots of clear and terrifying ones. Like I said, I think it's incredibly compelling and lots of people everywhere of different backgrounds and professions have claimed to see them. I personally just can't write off every single UFO story as craziness. But I'd like to see them with my own eyes.

I consider that to be the most rational way to approach it. This technically means that alien life exists somewhere on some faroff planet in some primitive form. Although I wonder if that means they could also exist in a highly advanced form? Moreso than humans?

Maybe. Given the size and rich bounty of galaxies and planets in the universe, I'd say the chances of that being possible are very high. But I'd still like to see these "visitors" for myself.

I'm really jealous of anyone who claims to have had a convincing sighting or encounter. My brother had one, and he actually called me while it was happening, and he was scared out of his mind. As terrifying as it might be to see a UFO, I'd still love to be a part of it. The ones who have had experiences so strong that they live the rest of their lives "knowing".

 

[LoFr3Eq]

I'm not sure if "They've visited already!!!", but the chances are very very high of extraterrestrial life existing.

We can even use math to find out...

So we live in the universe U, as far as we know we can observe about 1% - 5% of the universe (stay with me folks, but it could be even smaller) and There is life on 1 observable planet in this sector so far lets call this E.

Now, the amount of planets in the universe that can support life is N, and we know life exists on at least one planet.

so... N = UE or round about, and since the universe is technically 'universal' there should by some calculations be life on another planet somewhere.

-----------------

Now there is also another set of equations to consider.

Earth orbits around Sol in a Star-size to distance ratio known as the 'Goldilocks Zone', the chances of this occurring are fairly low, say less than 0.001%. In this zone there is enough light and heat energy coming from the star to keep the water on the surface of the planet in a liquid form for most of the time. This is important for at least carbon based life (unless there is only carbon based life, in which case I mean life) needs liquid water to easily stabilise and populate.

There are also other things to consider like weight of the system star, age of the star, wavelength of light coming from the star, number of planets, moons of planet.

Lets say that we know that the perfect conditions have known to exist at least once in the observable universe (possibly more). Now we just take the percentage of any given star supporting life (around 0.0000000000000001% (call this r) after taking everything into consideration), and then multiplying that by the amount of stars in the universe (technically infinite). So, from this we can determine that N = rU and N will be greater than 1. We then can see that there will be many stars that can support life, the question is, that we're still trying to figure out, is "How does life begin on a planet, given that the planet in question can support life?"




Once we can answer that question, the search for ET will be a whole lot closer to finishing.

Edit: Also, the life I am referring to does not necessarily mean intelligent life.

 

[Ampersand]

The fact that life exists here is proof enough that there is life elsewhere as well and an awful lot of it too.

 

[mstickle]

As others have said it's stupid to assume that we are the only life out there. But who knows? We may not even recognise other forms of life if we came across it.

I guess what I mean is; what we understand to be life and what we assume is required for life could be so different from other life in the vastness of the universe, we might not realise what it was or be looking in the right places. We've only encountered life from this planet so I think our understanding of life is insufficient to look at a planet and say planet A can support life and planet B can't. Hell planet C could be a life form itself for all we know.

 

[Roserari]

Universe is immensely and unbelievably huge. There's bound to be life somewhere out there. Whether it be insects, animals or humanoids. Somewhere, there has to be something.

 

[Stublore]

I doubt if Earth is the only planet to support life, or ever will be.
There is probably life out there somewhere, or there was or will be.
However I seem to remember that the chance of 2 advanced civilisations occurring in the same area is pretty much nil .
So for me there are no grays, and we have not been visited by anal obsessed extra-terrestrial pervs.
