Do you believe in extraterrestrial life?

And I don't necessary mean UFOs,but even viruses and microbes in other galaxies.

I don't think we are on the only planet in the universe
that supports life.

There are so many planets out there; some form of life must exist somewhere.

life on other planets.

There are more stars in our galaxy than there are grains of sand on the earth. Think about that...and that's just our galaxy....there are billions of galaxies out there (maybe trillions).

There's no way we could be the only ones, just because of the sheer number of stars. You have better odds of winning the lottery every day of your life, than the odds of there being no other life anywhere in the universe.

I don't think that any other life has visited the Earth, but I know there are other planets with life on it.

to allow any type of life.

I think it's a statistical standoff.

The Rules could be different elsewhere.

as one might think. This was demonstrated by the Miller Experiment. They just used water, hydrogen, ammonia, methane, and an electric arc--and voila! In a little while there were amino acids and other basic components of life. A few variations on the early atmosphere of earth yielded similar results.

If you combine this with the Drake equation and Geoff Marcy's work on extrasolar planets, then it starts to look like a statistical probability.

Just my .02.

I think it's likely that complex life forms have evolved in other star systems as long as there are conditions for the creation of collections of complex molecules that self-replicate and are randomly modified in large populations in an environment that's stable long enough for selection of successful modifications. Ideally, such creatures would be friendly, consume large quantities of greenhouse gasses and piss oil.

I've had a rash for almost a week now. :rofl:

been to earth.

I believe there is other sentient life in the universe. I do not believe it has ever been here, however.

It seems inconceivable that given that vastness of known space, no other self-reflective bio-chemical processes have come about.

OTOH, given the vastness of space, it seems inconceivable that any other self-reflective bio-chemical processes have spent 15,000 years to get here (if the speed of light is indeed inviolate, that's how long it takes us to get to the nearest star right now). Considering that humans don't even have a reliable way to transmit the message, "Wait for the return message", even 1,000 years into the future much less tens of thousands of years, I'm not terribly surprised that we haven't had direct communications with another sentient species at this point.

Need scientific proof.

I am agnostic on a few things too.

:)

:rofl:

There is just so much out there, even the evidence we have of possible water on Mars points to possible life on other planets.

I think there was something that life could be possible on one of the moons of Saturn or Jupiter, far beneath the ice.

Contact is one of my favorite movies, so this is a good question.

:hi:

Ann Druyan: " didn't want to believe. He wanted to know."

I *believe* it to be highly likely, but all we *know* right now is only that it's happened at least once. A complete theory of biogenesis would help for starters.

Say the universe contains a hundred billion galaxies each containing a hundred billion stars on average. That gives us 10^22 stars. But what if life is so uncommon that it's less than a 1 in 10^22 shot?

Either we are alone or we are not. Both possibilities are compelling.

Especially looking at Mars, and that moon. If that much chance of current life, or prior life exists/existed in our solar system, imagine how many more solar systems, planets, and even moons might support it.

:)

to believe we are all there is.

Would that be arrogant? :)

:shrug:

:)

My science teacher made a good point last year.

"Every star gives off light and heat. If just 1 in every 10,000 stars was like ours, and just every 1 in 10,000 of those supported a planet like earth... That's still a lot of numbers. That would be more earths that people that are on this planet at this very moment."

But in that case odds are that intelligent, human-like life only lasts in a detectable state for a cosmically short period of time, or otherwise there would be metric tons of evidence all around for us to find. So either we are alone, or our type tends to die off before any lasting imprint is left on the universe.

And Yes I am blond & from outer space.

?

...but not from Planet IX from Outer Space...;-)

Thanks for the clarification. ;)

:shrug:

I mean, how can there not be?

I just hope they are friendly (and that we don't just shoot first and ask questions later if and when they arrive).

We'll have every gun we can get our hands on trained on 'em. :eyes:

We distrust each other; we're exponentially so about that which we do not understand.

If there is other intelligent life, and it happens to contact us in my lifetime, I should hope to attempt communication. So I hope they land at my house.

and I forgot that when Klaatu first exists his ship and pulls out a device he was going to give the president of the United States, some scared/nervous soldiers shoots him and knocks it out of his hand. Not to mention the hundreds of soldiers with their guns trained on him! How sad.

If they landed smack in the middle of D.C.? With today's paranoia?

They'd never get to land without a force field or materials that make titanium look like popsicle sticks glued together, though. We'd have a squadron of FA-18s and banks of SAMs on 'em long before that.

I'd say there is only the remotest of possibility that there isn't sentient life as well.

that somewhere in the galaxy there has to be somewhere else where life has evolved.

The universe is a huge place...you'd have to be totally superstitious to think that our planet is the only one out of a potentially infinite number of worlds that supports life.

DUH

I've seen no evidence to suggest that universe revolves around us earthlings (human, animal, viral or microbial).

I don't believe two places having life will ever be able to communicate, but I think that life is a natural consequence of the chemistry of carbon, hydrogen nitrogen, and oxygen. It may be rare, but the scale of the universe certainly suggests it is not unknown elsewhere.

I would be surprised if there aren't at least microbes elsewhere, maybe even in this solar system. I'm uncertain about intelligence elsewhere. We always assume that they would be more or less like us -- but they might be so totally different (so "alien") that we wouldn't be able to communicate with them, understand their motivations, or even recognize them as beings.

It would be arrogant for us to think that we've it in something as vast as the universe and beyond. There's something or somebody out there, but I can't imagine what or who!

I'm sure there is advanced life out there - we're probably primitive compared to some.

With such a wondrously vast magnitude of suns and their planets, I think it's highly likely that other forms of life have evolved elsewhere in the universe.

I just hope there aren't any bugmen. I hate bugmen.
