Why or why not?

Thanks

possible.

but i doubt we will ever know. there are organisms in other planets (bacteria, etc) so who knows. There are a few earth-like planets out there though.

[spiveker]

There could be life, but the problem is considering 'Life as we know it' perhaps, we're looking for the wrong sort of life. Maybe not all life forms are mostly carbon based...

[Saduyre9de]

Serious question?
No there are not likely humans on other planets - it is unlikely life would evolve in an identical pattern to on earth on a place that is not earth

Life out there is basically guaranteed however.

[Pashtet]

Human? Nope; this is pretty close to impossible.

Other? Practically guaranteed, considering how huge the universe is...



Keep in mind, this is only the observable universe.

[mortgrhhh]

no, it dosent really make any sence. life cant exist on other planets

[abossakon]

It seems that there were signs of life on Mars, so why wouldn't there be life elsewhere? Now would there be human life? Probably not. However, I do believe the existence of life on another planet is almost a guarantee. Will we ever meet them in our lifetime? Highly doubt it.

elevate7 - for denying the existence of life on other planets, your house will be blown up by a Namekian. Good day sir....

There cannot be humans on another planet. The exact coincidences that occurred here to allow the formation of humans were a one in an infinite amount of possibilities. However, life most likely exists outside of the planet. Most of it is probably single cellular, and hasn't reached a point where evolution into a larger organism is possible. However, there is probably at least one other planet (or other celestial body) with intelligent life.

That we've observed - we have a lot of trouble getting info on extrasolar planets. To make a blanket dismissal like that is to be ignorant not only of probabilities but of things we've actuially observed.

It's very, very possible that life could have in the past existed on Europa (moon of jupiter) and could again.

[AlexDatig]

Life, single celled, or evolved. It's almost insulting to say it doesn't exist. we have found single cell bacteria on planets (Can't remember which ones but they are there) And those are just the ones we can reach. Our universe is an ever expanding mass, bigger than anyone can ever imagine or picture. Somewhere, maybe multiple places, like events that brought life here, could do the same, given the right circumstances, and enough time, life is achievable. Human? Oh hell no, but something, even just a plant. Plants are nice.

[comprar-espana]

no there arent any humans on other planets.

extra-terrestrial life, yes. humans, no.

[VEGLAS - SPB]

no not human but there is more than likely outher complex life out there

[fapourfasiark]

I'm a firm believer in life on other planets, can't remember how many to exact but there are apparently many earth like planets which are habitable. In theory humans could live on them if the conditions are right, but what are the chances of the lifeforms if any on these planets will take a similar course to ours and produce humans? Remember that conditions are going to differ and we've simply evolved to adapt to our living conditions. I'm not saying there couldn't be something similar, as I'm always open to possibility, but humans as we know them? I doubt it.

Life could be based around silicon, or even germanium if we get really technical. Also, we have already found organisms that can use arsenic as a means to live on Earth, a planet where almost all of it's organisms find arsenic extremely toxic.

Anyway, humans on other planets? Highly unlikely. Although, there are still some who believe the whole "Earth was seeded with life by aliens" so you never know.

Pretty much what Crad said.
