Do you believe in life outside of earth?

I think that there may be life on other planets, I do not know. This life may be intelligent or unintelligent, again, I do not know. I certainly believe that life is a possibility.

I think it’s probable, given the vastness of the universe and the great number of other solar systems in existence. Now, whether or not this life is sentient is another matter.. I also think it’s probable, but may be limited to bacteria and such.

Do I believe it exist? I don’t know.
Do I believe it can exist? Yes! Why not? We do!

I find it statistically quite probable, but I doubt I’ll ever know definitively.

Yes i definitely do. Ill even go so far as to believe that somewhere on one of those planets in the galaxy there is a person on a communication device, asking or trying to answer that same question. Definitely there is life out there!!!!!

I believe that there has to be something out there!
I wonder to whom they blame their existence, that would be interesting.

@Zombie345trioxin . Have they ever visited earth? That is the question?

I think it is likely but that it is probably not in the form of little green men or any other alien caricature that we often use to represent extraterrestrial life.

Yes, but it is such a vague possibility that it doesn’t even matter now. Are you even aware how large space is and the amount of light years that separate us from other galaxies even? It’s extremely unlikely that we are the only organisms in the entire cosmos.

Yes. It is on the international space station at this moment.

Even if there IS life elsewhere in the universe…it’s a big SO WHAT? I think it’s more likely that we can’t get to them and they can’t get to us. Oh, it would be really cool….but probably won’t happen. If it has already happened, our governments won’t tell us the truth anyway, after all….they rarely tell us the truth about anything.

In any of the religious books, i wonder if there are any hints to other life out there? Hmmm if we look at the bible, there is a scripture that says MY FATHERS HOUSE HAS MANY MANSIONS. That could be a hint…...

I find it hard to imagine that there isn’t life on other planets. With the size of the universe and all the galaxies that we don’t even know about as yet there has to be something else other than us. It makes me feel very small just thinking about it.

In the near future we would know the truth. We would develop our space rockets to go visit and explore ourselves.

Sure. There’s probably life in many places in the universe. Maybe even in other places of our galaxy. But if that was the case, any light or signals received on earth will be up to 100 000 years old. What we see don’t exist in that way today. If we would find proof of life, the only thing we could do is go “Oh, isn’t that the darndest!”. But it would be fantastic none the less.

Somewhere out there in space, a jelly like alien is probably asking this question.

@cornbird Uhhhmmmm…..Are you serious lol? If you are I would like to know how a civilization of people that didn’t even know anything about their own planet would or could know anything about the space outside of their earth.

Aliens walk among us disguised as humans.

1. The universe is so unimaginably vast that I think it’s almost certain that watery, carbony, cell-based lifeforms exist elsewhere.

2. Our definition of “life” is sort of weird and arbitrary. Basically, we define life as anything that’s based on a cell structure. Cells are made of of lipid membranes the enclose a watery solution with carbohydrates, proteins, and nucleic acids. The last ones can store data. The data can copy itself, along with the entire structure of the cell.

The lipids, carbohydrates, proteins, and nucleic acids, in turn, are each composed of chains or groups of smaller molecules and atoms, found in abundance on Earth.

What we call “life” is actually an extremely complicated group of patterns. Such patterns evolved on earth around the unique conditions here. But I seriously, seriously doubt that they are the only kinds of patterns that can give rise to the kind of thing that we call “life.” I think that as we explore the universe—and also as we explore the boundaries of biology and chemistry—we’ll see that our definition of “life” is actually quite parochial.

Well, okay Qinqu, but if they come here, we’re taxing them on thier carbon percentage :D:D:D GA, by the way :)

And I loved Jacket’s answer – I’ll be darned! LOL!!

Yep! There sure are! Here, too :)

I believe there is life outside of Earth. With all of the space that’s out there I find it naive to think we are the only life.

Yes, I do.

I toy with the possibility.
There is nothing in the universe that I’d love more than to know of the existence of extraterrestrial life.
Considering how many billions of stars there are, and how much time has passed since the universe’s creation, chances are good. But also, considering how many stars there are, the chances of that life being near us are slim.

Simple life yes. Complex multicellular life is probably quite rare, present perhaps in 1 out of 10,000 galaxies. If you’re really interested in this subject I recommend this book:

http://www.amazon.com/Rare-Earth-Complex-Uncommon-Universe/dp/0387952896/

@Blackberry We would achieve that and I even believe that we would even invent something like warp/hyper drive too. For us,anything is possible.

@mattbrowne Sounds interesting. Is that book still relevant in it’s assumptions? It was written before they had discovered other planetary systems and possible water planets.

I think it’s very likely that there’s some life out there somewhere. Even if it’s only some sort of bacteria or plankton. What I don’t believe, is that aliens are coming to Earth and abducting people.

@Jacket – Yes, it’s still relevant. The first extrasolar planets were detected in 1995 (or even a little before). At the time of writing dozens of planets had been discovered already and the authors speculated that it’s very likely that many in the habitable zones will have (liquid) water. In fact they assume that simple life is very common in the Milky Way taking some of the astrochemical findings into account. They deal with the question what is required for the evolution of complex life which is likely to take hundreds of millions if not billions of years. There are many factors like size of the mother star, rotation speed of the planet, aixs tilt, plate tectonics, number of moons and many more.

Finding possible water planets does not change their basic findings.

Not only do I believe in it but I’m 99.99% sure it does exist. The case for it far outweighs the case against it.
