Do you believe in life outside our planet?

Do 'aliens' exist? Why or why not?

Yeah, there have been plenty of people who claimed to have been visited by aliens from other galaxies.   The question still remains, if these aliens have been visiting earth for many years, why don't they show their faces?  I think it is about time, don't you think?  So no, I don't believe in them.

tink

Do I think there is sentient life elsewhere in the universe or even within our galaxy?  Of course.  To think otherwise would be the ultimate in egotism.  Do I believe that this sentient life has visited here?  Probably not (although there have been a couple of people I worked with over the years I'm not sure of ).  I mean after all, if you had the means to travel billions of miles through space, would you want to visit the insanity that is us.  I don't think so!!!!

Sure. The probability that life of one form or another exists elsewhere is very high based upon the total number of stars (each of which might have its own solar system).The exact number of stars is unknown, but it is in the billions
of billions range...that is a fairly large number.  Will they come here?  I coincide with BeverlyAnn, why on bloddy hell will they waste millions of light years coming here?  We've got nothing special.

yea. da universe is to damn big for us to be da only people here.

I believe that the universe as we know it is only a small portion compared to what we have not explored. Why would we be the only life form?  Now that there is overwhelming proof of aliens is debatable. If indeed even one tangible shred of absolute evidence did exist, this question would not have been asked. That being said, it's hard to believe that the only life forms in this immense universe are on planet Earth.

according to the drake-sagan equation the galaxy should be jam-packed with alien civilizations chattering away like m->-bleeped-<-ies. thousands or millions of the things.  unfortunately SETI has found absolutely no evidence for anybody communicating anywhere, except for us.

the great physicist fermi asked the question "where are they?" any technological civilization should be able to colonize the galaxy within 5 to 50 million years. the trouble is, there is absolutely no evidence on earth of any visit in the past. none.

now, it is very possible the drake-sagan equation is wrong, especially in the section that deals with the development of life. actually not life itself, that is probably exceedingly common. the major problem is probably the jump from single celled animals to multi-celled animals. The number of planets where that developed may easily be one. us.

another problem, foreseen by drake and sagan is the lifetime of technical civilizations. do they destroy themselves before they can begin interstellar colonization? do they exhaust their resources before they can leave?  what the hell are they thinking if they are there watching us from afar?

my personal feeling is that even if they did develop, even if they did manage to survive their atomic era, the difficulties of interstellar travel are insurmountable. we will never know.  so there.

"Outside our planet?"  Do you mean as opposed to "inside our planet?"

Depends on how you define life... The current feeling is that there is microbiotic life on Mars.

I think you can guaranty that there are and have been civilizations out there the problem is the distances involved in travel to where there maybe life.. also finding life at a similar stage to us would be difficult as we have really only been looking for a milisecond compared to the life of the universe.

One thing I will say though is that I dont think we have been visited because if a civilization could manage to conquer the vast tracts of space. they are going to do one of two things either conquer us or make friends with us. They are hardly going to turn up in the UK and make nice patterns in the corn or deepest Arizona and abduct the odd passerby. Its just not realistic

Quotethey are going to do one of two things either conquer us or make friends with us

There are a lot more options than that, even only looking at it from our perspective. It could be that we do not have the ability to know that they are doing something, perhaps even in another dimension we can not detect.

but why would they bother? the technology needed to cross the vast tracts of spacce seem to me to preclude messing about looking at at individual humans.... If thry can come here they will most probably announce it in one of two ways.... but then again you never know do you ?

The dimensional thing actually fits in with some theories about God which are pretty interesting

I believe in the "possibility" of them. I believe that God created everything we know and everything we don't know. And there is so much out there that we haven't yet discovered, I feel it's pretty pompous of us earthly humans to think we are the only life He created anywhere.

The basic building blocks of life, amino acids, exist everywhere in the universe.  It is a by product of the stars.  I believe that life does exist everywhere.

I  believe that the only aliens that have visited us are from other countries, not planets.

I don't believe that interstellar travel is possible.  I'm perfectly willing to change my mind on this one however if someone can show me something new on the subject.  Unlike all the technologies we enjoy today, nothing we know now gives us a hint that it will ever be possible.

Ok I deleted my post because I read back and noticed you took the words right out of my mouth. This is EXACTLY how I feel.
Thanks Jeannette 

The universe that we know of stretches billions and trillions of miles.  I am of the belief that there are extraterrestials everywhere far away.  On one hand I want to see what they look like and how they act and communicate but on the other hand I don't want to know.  Then again, I probably wouldn't mind living with some extraterrestials of they offer a comprehensive healthcare package at an affordable price along with cheesecake.

I think it is unlikely for life to not form itself. Also unlikely that said life will fail to invent cheesecake. Hugs, Devlyn

Another "old thread"? Somebody is STALKING you N**O ! Of course there is !

I often wonder whether, on some distant world, there are beings asking if we exist.

I do believe in the existence of  extraterrestrial intelligent and non-intelligent life forms because of the laws of probability favor them.

Some of the unexplained UFO data also points to their existence
