Don't ever say there is proof if there isn't proof, otherwise you need to cite sources and back it up.
Why are you bugging me with this when it has next to nothing to do with the topic of the thread? And why must I bring forth evidence, but not the person who originally made the claim?http://en.wikipedia.org/wiki/Behavioral_modernity#Timing posted:
You statements made no sense to me, especially since you didn't refer to anything, seemingly taking them from thin air.
Taking a freaking hypothesis for granted and as facts has no place in this section. And why does it matter who I ask for evidence? I should be able to ask anyone here for evidence and they should produce it for me. In this case you made the statements, and I asked you to back them.
If you see someone saying stupid things, then ask him for evidence, if he can't produce it report him or PM a mod.
It's literally impossible for us to be alone in the universe. I doubt the other races are advanced enough to make contact tho.

No, and there probably won't be for a long time. Our broadcasts have only gone something like 80 LY, which probably isn't enough. It's hard enough to tell if earth even has intelligent life from "space", we might as well not exist.
I'm in Neil Degrasse Tyson's camp with this.. if aliens came here and crashed, I don't want to meet stupid aliens. What a load of shit. So your aliens can cross interstellar space but can't enter an atmosphere and land on some desert flats or something?
OK, the next time someone says that there are certainly beings living in the universe besides Humans, I will challenge them. If they can't back up their claim, I will PM Swebonny. So please don't continue to make baseless claims.
Other lifeforms than those on earth? Definitely!
Alien lifeforms on earth? No.
Well, what in the hell? Aliens? Goddang Aliens? You people are just asinine, I tell you what. Aliens do not exist. Period. My idiot neighbor believes they do, but he's a nutcase. Can't even tell his wife is having an affair with another man. Talk about something a lot more fascinating, like propane! But heaven forbid you talk about those other bastard gases. To hell with charcoal too.
Aliens do not exist on this planet. There is a high chance for them to exist other places in the universe.
Considering the size of space, I'm sure they do exist. But, because space is so huge, it's not likely we'll ever meet any extraterrestrials.
Seeing as how the universe is infinite, suggesting that we are the only intelligent/sentient/living things is just plain stupid. Do aliens exist? Yes, very much so. Have they visited Earth? I doubt it, it takes millions of years to get around galaxies. Most people assume that "Oh aliens are so super advanced and they probably look down to us as if we were little atoms and insignificant", but in reality I think aliens and humans are at the same level. Some may be more primitive, or advanced, or maybe the same level as us. But they may be just as afraid as the concept of us as we would be to them. Will there be mass hysteria, spase warz, genocide if we found aliens/vise versa, potentially. Would there be a revolution in humanity and there to be a whole new race of advanced beings? Potentially. There are just too many possibilities, jumping straight to "End of humanity" is just as stupid as not beliving in them.
I believe that somewhere in the universe there is at least one planet other than ours that have intelligent life-forms. To believe otherwise is ridiculous, the universe is too large for us to be completely alone (and remember, absence of proof =/= proof of absence). However, I doubt our species will survive long enough to achieve the kind of space flight technology that would allow our civilizations to meet (if the technology is possible at all, not to mention that the chances that we'd be able to contact another species within our own galaxy are astronomical at best).
The only argument against the existence of extra-terrastials is the fact that we haven't heard from any. Unless we for some reason are the first, or one of the first intelligent species there would have been countless species that developed radio millenia or even years ago. Would these not let there presence be known in the universe by radio or similar?
I believe if you think this one tiny particle in space we call "Earth" is the only pool of life your ignorant
I'm betting he believes that we don't know if there's sentient life out there. We have prediction models that say there might or might not be. Think of weather forecasts; cloudy with a 15% chance of sentience. Nothing is certain or proven.
And he didn't claim that the universe is infinite. He said we don't know if it is. There's a lot of things we don't know.
I am just saying we don't know, because nothing has been proven. There is no proof of if the universe goes on forever or not. There is also no proof of if there is alien life form out there. So I take the amazing view of saying "I don't know" - because that is the truth.
We don't know.
I'll repeat it one more time.
We don't know.
I'm sorry. I'm sorry. You might say "It would be so sad to be in the universe all alone" and yes, it is sad. But it's fact.
Just a protip for King Tiger, please don't assume you are the sultan of the cosmos and you can whip factual information from your brain. You literally claimed, "But it's fact." No sir... No.
TIDE GOES IN TIDE GOES OUT, YOU CANT SPLAIN THAT
So until you stop claiming aliens exist or that "we don't know" if they exist, I claim that "we don't know" that a giant purple invisi-elephant is floating over New York.
Alright, new hypothesis. Underneath the surface of Mars, there are trillions of oompa loompas plotting to destroy all human civilization.
And the elephant was undetectable and could maneuver out of the way of any tracking technology because it moves just under the speed of light.
Exterrestrials do not have to be intelligent beings outside of Earth. They can be simple bacteria which are not in Earth, and there is some limited evidence that nanobacteria have lived in Mars through the Allan Hills 84001 meteorite that landed in Antarctica. However it is still debated if it was biotic or abiotic as there are many variables that go against this claim.
