Yes, life is out there, but it may be very different than life on earth. Will we recognize it as life?

How do we define "life" - i.e. - does life need to breath oxygen? Does life need to be made up of carbon? Does it need to be sentient? Does it need intelligence? Does it need a life cycle? Stars, for example, have a life cycle. They are born, they grow, they deteriorate, and then they die. Are they living? Why not?

I like Calvin's (Calvin & Hobbes) answer best:

"Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us."

Great thread, YES!

Well im a future astrophysicist so i should know somewhat, so let me explain my thoughts on aliens hah, so we live in a galaxy, this galaxy contains billions of stars, and there are as many galaxies as there are stars in our galaxy and there are more planets than there are stars so think about it, what are the chances of another star having a planet at the right distance like ours that harbors life? Theyre pretty high right, but what are our chances of ever meeting finding ET life? Not good lol, what i am sure of is, there is ET organisms and microbes in outer space but advanced life is rare, because it takes a long time to become advanced lol and im theyre so far that by the time our radio signals reach them we will not be here anymore

I don't know but if they do exist wouldn't they be about as advanced as we are?

Yes there are aliens!!!!! And they hop the border and come from Mexico

Literally

Love all of these answers guys.

Also, 15 yes, 0 No!

Seems clear on TFO's stance!

well im not really i nerd or a geek but i love space. and there are BILLIONS of planets, how can we bo the only one that can have life?

HA.HA. SO FUNNY

Exactly.

And who's to say, that at one point in time, maybe millions of years ago even, that the other planets in our solar system had life on them?

Sure they are either too far or too close to the sun to be habitable now, but what if, just like earth, they had an atmosphere that was customarily suited for them to make them inhabitable?

Sure, there's bound to be tons of planets that never had anything on them, but there's tons more that have.

it would be cool to know for sure, but it even if we knew, we wouldnt be able to communicate or travel to there planet because it would have to be FAR away. unless there in alien craft that can go hypersonic (think thats what its called ) and enter our planet

I think I was just abducted, a certain part of my body hurts.

In a few million years or a billion, the sun will have grown and earth will be burned and mars will be in the "goldilocks zone" which means habitable zone, it will be able to sustain life, but by then, the sun will be almost out of gas literally, but we might not even be around by then judging by how were always in wars and such, but hey its possible for deep space travel maybe, sadly i wont be alive for that haha, but yea we probably wont meet any intelligent life anytime soon

Science Fiction fan eh? You like "Falling Skies"?

17-0.

And I haven't heard of it, but I'll be sure to google that.

I don't mind aliens coming here as long as they become citizens, pay their taxes and...

...oh, you mean the other aliens! Yeah, whatever, them too.
