The most clear and convincing evidence that aliens exist is that none of them have tried to contact us.
not really. When we manage to travel the stars we will sow destruction and death across the galaxy. It's a smart move to kill us now.Chefodeath said:You know, even saying that you think the aliens would care enough to destroy us speaks of a supreme kind of arrogance.spartan231490 said:Yes and no. If they have, I imagine they would have exterminated the blight that is the human race, or at least close.
I'm reluctant to either ascent to or deny the possibility of aliens because we still don't have a good idea of how often biogenesis occurs in nature. Still, the universe is disgustingly huge, so I'm inclined to answer in the affirmative.
As for aliens visiting earth, I highly doubt it. The same thing which makes me say that aliens probably exist, the utter hugeness of space, is the same thing which makes the chance of contact utterly miniscule.
Edit: So apparently this is my 666th post. Um...Hail Satan?
If the were as bad or worse they would have killed our men, raped our women, and pillaged our land, just like every human race ever has.Tax_Document said:What if they're just as bad if not worse? HMM?spartan231490 said:Yes and no. If they have, I imagine they would have exterminated the blight that is the human race, or at least close.
Humans are generally good, only a few bad kittens.
Well I can't say for you personally, but where I live it's a small town, in the Victorian Countryside, everyone helps each other our, however, I have noticed in the cities I go to that people are generally more selfish.spartan231490 said:If the were as bad or worse they would have killed our men, raped our women, and pillaged our land, just like every human race ever has.Tax_Document said:What if they're just as bad if not worse?

As for humans being generally good, that's crap. Humans aren't generally good or generally evil, they are generally selfish. which is not an unreasonable thing, if you think about it.
Fermi's Paradox is... ugh.)rStrangelove]Dunno if this has been mentioned yet, but this whole thread is actually about the
FERMI PARADOX - WHERE IS EVERYONE?
"The Fermi paradox (Fermi's paradox or Fermi-paradox) is the apparent contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations."
http://en.wikipedia.org/wiki/Fermi_paradox
Very interesting indeed. To say that "its impossible to meet aliens in space, the universe is far too big" is too simple, its a little more complicated.
DracoSuave said:Fermi's Paradox is... ugh.
Let's take the attempt we've made to communicate to outerspace that's travelled the farthest, the Arecibo message. We broadcasted that in 1974. Now assuming that an alien culture could detect it AND decode it AND send us back a message, that would leave almost 38 years for the back and forth travel. That means that their world would have to be a maximum of 19 light years away. There's less than 100 stars in the universe close enough for such a message to be relayed back to us. Of those 100, few of them are the right type to support life--this ignoring the possibility of actually having said planet.
It's not impossible to communicate with other systems, by no means. But so long as we're relying on methods that involve the speed of light, it's not in the slightest bit rational to make any conclusion involving the lack of results over the very SHORT amount of time we've been searching and broadcasting.
The paradox involves an irrational premise, and thus... ugh.
5.1 Few, if any, other civilizations currently exist

What? No. Electromagnetic waves can only travel at a certain speed, no more, no less. There's no shortsightedness, a beam travelling at one light-year per year can only have reached 38 light-years away! That's a direct calculation!)rStrangelove]DracoSuave said:Fermi's Paradox is... ugh.

You're still only make a guess because of the scale of the universe and the nearest number of inhabitable systems. Isnt that shortsighted a bit?
That doesn't change the fact that said platform still has to be, at maximum, 19 light-years away for them to even have a chance of receiving the message and returning it by now. A 19 light-year radius sphere around the earth is a very small sphere taken in astronomical terms.If one has the tech to travel far distances dont you think one could also construct large generation-ships or carriers or whatever you call it, and therefore they might not be dependant on any habitable systems at all? Travelling space stations like the Deathstar dont need Earthlike planets to survive.
But the paradox itself is fundamentally flawed, based on ill conceived premises. If a paradox is itself ill conceived, that means it's not a paradox, but simply a misunderstanding.All in all, i just wanted to say, the matter is far more complicated than just taking the sheer scale into account.
The paradox lists these reasons/points:

DracoSuave said:Fermi's paradox is like when a guy who lives alone wakes up and after going about his day decides it's odd he hasn't encountered anyone, and ponders that there's a paradox in that he hasn't met anyone lately but the world is so large there's got to be people out there. Meanwhile, he hasn't left his apartment yet.
