There is no way you can't believe in aliens. With the number of planets and stars out there, no matter how small the odds are, there is alien life out there. I'm relatively certain that there is intelligent life out there for that matter. have they ever "visited" us, this one is a no.shadowsoul222 said:Pretty self-explanatory, do you think that aliens (non-human/non earthlings) exist? if so what do you think they will be like? and do you think that we will discover them or they discover us?
Personally...I'm not really sure. I never used to but recently after playing through Mass Effect I want to believe in them haha.
Of course, the big issue with that is that there may well be 30,000 civilization-supporting systems in the galaxy. But what are the chances that they've got civilization on them at the exact same time as us? You could space civilizations out over 300,000 years with the history of the galaxy, and us humans are panicking about surviving the next ~200.ColeusRattus said:Mathematically, it's quite unlikely that we are the only intelligent life - let alone the only life - in this universe. So I can say that yes, I am convinced that "we are not alone".
Our galaxy, the milky way, alone has up to 300 billion stars. That's 300,000,000,000. Now if only every tenth star has planets, that's still 30,000,000,000 (30 billion). Now if one in every thousand solar systems would have life, that would still be 30,000,000 (30 million) systems. Now if one of every thousand systems with a planet with life sports intelligent life, that would still be 30,000 (30 thousand) systems and thus civilizations.
So far as we know. Just because we don't know how to accomplish faster than light travel, doesn't mean that it is impossible. However, I don't think we have been "visited" either. Would you want to visit a species as violent as us? I wouldn't.thylasos said:Bacteria and so on, within relatively easy reach on astronomical terms, I can believe that that's possible.
As it is, interstellar travel reuires such a preposterous amount of time and energy that it's extremely unlikely that anything vaguely intelligent, let alone anthropomorphic, with which we could conceivably communicate, will encounter our area of space until long after our solar systems planets have been destroyed (or made completely uninhabitable) by the procession of our sun's life cycle.
Not really. The Universe is almost infinitely large. Mathematics state that if something has occured once (in this case, life) then the larger the sample size the more likely it is that it occurs again. As the Universe is almost infinite, it is almost certain that life has occured elsewhere.SilentCom said:The belief in extraterrestrial life is just that, a belief. Unless there is confirmation, I would have to say no.
