There has to be life outside of our universe. There is an incredible number of planets and stars and galaxies beyond our own;a number far beyond human comprehension. Our evolution is imperfect and flawed, yet we have still become the most powerful and intelligent species within millions and millions of miles. Conditions like ours that can support life could very easily arise somewhere else in the universe. THere has been such a wide window of time, and so much space for it to happen, that it is inevitable that there is life somewhere else in the universe. If we can exist, why should we be the only ones?
There are many planets , with supstences of H2o *Water* on them . Where there is water there can be life. Since the earliest hominid species diverged from the ancestor we share with modern African apes, 5 to 8 million years ago, there have been at least a dozen different species of these humanlike creatures. Many of these hominid species are close relatives, but not human ancestors. But it only takes one to evolve creating a sucsessful species, just takes two animals with good offspring to create a more human like spcies. Most scientist say that Earth started out as a *star* that was mostly mad out of valcanos, and that many meteors hit earth making its huge trenches within our ocean. But after all of the meteors hit earth , it started to rain , for Billions of years, Then formed an Ice age ... Which soon after melted making land and our oceans . And within our oceans life began... But of course *humans were first evolved by creatures that lived in water . All there has to be within that water is bacteria, which could form into something over time. Then create a Ape like animal , *Which is a close ancestor to hominids*.
Well the point of planet earths history is , it could have happend some where else , within our Solar System or not. Maybe billions of light years away.
If you have any thing you would like to say just post on this fourm . Im going to keep this on my page. Hope it gets somewhere.
It's incredibly arrogant to think that in all the cosmos we're the only sentient species, it's arrogant to think that life can only survive on a planet like ours, we don't even know the actual surface conditions of some planets.
However it's all too possible that in the species that may or not be out there, they're still in the caveman stage or so far ahead of us that to them, we're in the caveman stage. I think all we can do is continue improving our technology and begin expanding outwards, of course if we do colonize we have to make sure that we take no disease or bacteria with us, otherwise if there is a local population or even the possibility of one, we could do it what the European's did to the Native Americans.
I'm open to bacteria, plants, and even some simple animals, but I don't really think people will find the so-called "grey aliens" they're looking for. I used to believe in them, but I'm also very open to ghosts and the such. You might ask, "So, what do ghosts have to do with aliens?" My response: If ghosts are the trapped souls of people on earth (or something along those lines), then for intelligent beings, other than people, to exist they would probably have souls and therefore ghosts. And I can't fathom the idea of alien ghosts. (BTW, Star Wars was a movie, Yoda's ghost spoke English, so that doesn't count :P)
I'm pretty sure there is life out there, sort of what Joe said, mostly bacterias and with a bit of luck even plants, animals, fungi or such. But nothing too complex, and surely no civilization. Not at the same time as ours; who knows, maybe there was one once, or there may be an other once, but I sverely doubt two civilizations arise on different planets at the exact same moment (cosmologically speaking). Hey, they have found traces of what looks like periodically lotic water on mars. Could be a starting point.
why can't there be a planet 20.000 light years away whit a civilization on it? it's still possible right?
It's possible but the chance that there is a civilization out there right now is even more unprobable than a civilization existing at all. Just look at life on earth, how long it has been here already and how young our species is, and I'm not even speaking of civilizations who arose only in the past milleniums. I'm aware that if you say that the universe is infinite, there is an infinite probability for a civilization. But I'm sure we're the only one in our solar system, maybe even in our galaxy, and I wouldn't wonder if we had to search thousands of galaxies away until we find something like a sentient civilization.

but there is a civilization existing. we humans are just as much alien as aliens will be when we find them.

but how long can our species stay alive? dinosaurs roamed the earth for roughly 200 million years. we humans are not that long here at all. so maybe we also have 200 million years to go. that wold increase the probability of 2 or more civilizations existhing at the same time. especialy if you think about how fast a civilization can grow like it did whit humans.
But I'm sure we're the only one in our solar system, maybe even in our galaxy,
i agree on that. if they were that close we had found them by now.
but there is a civilization existing. we humans are just as much alien as aliens will be when we find them.
Yes, we are here, now. My point was more that the probability for there being a second, or even a third, civilization at this moment, is incredibly small compared to the chance of a civilization existing at all. It's more likely that civilizations arise and fall consecutively with a 'dead phase' in between.
Let's assume that one in a million planets have life every billion years. That means there is a 13.7 in a million chance that there has or was life elsewhere.
Do you know how many planets are out there? A lot. A lot of planets are out there.
And where there is simple, there is evolution. Where there is evolution, there are complex organisms. Surely in ten billion years there is a pretty good chance of sentient life?
Think of how creepy and wierd it would be that if in the future we sent a rocket and a crew to another solar system, they find a planet with inhabitants, and they turn out to be humans O.O

i think that by the time that we are able to send people to other stars. that we will understand evolution good enoufg to know that evolution always go's the same way. (if it turns out to be like that.)
I doubt it will always go the same way. Even if it starts the same, there's a lot of environmental factors that force the species to adapt/evolve differently. A slightly different atmosphere (maybe 1% less oxygen, 1% more CO2 than earth had) early on in the formation of the planet could drastically alter every form of life on that planet.
