I believe there are other life forms out there... Im not saying i believe that we are being visited by advanced beings who are millions of years ahead of us in technology... but I think there is other life out there.  Here on Earth there is live in the coldest of places and in the most inhospitible of places... miles under water, lifeforms living in sulfuric environments... the chances are just to great for there not to be life elsewhere.

I believe in life on other planets, i would even go as far to say i believe in highly intelligent life.

But i don't believe there's highly intelligent life in our solar system or that highly intelligent life is visiting us.

There are most definately other intelligent species in our galaxy or at least the universe.It is just to immense for there not to be other life.Google the drake equation/theory and you'll see what I mean.Then theres also the Distant Origin theory that "life" or rather the beginning of life, is carried by asteroids and comets throughout the universe, which infers the possibility that life on Earth came from an asteroid or comet and environmental factors on earth was favorable for the development of that life.

This then means that any other planet with favorable conditions will be able to support the development and evolution of life.
As to the question of "Are they here visiting us?", I dont know, I doubt it. But of course I have seen footage of things I cant just deny, so I'm kind of torn on that part of the debate.

Also known as Panspermia.


Quote

Panspermia (Greek: πανσπερμία from πᾶς/πᾶν (pas/pan) "all" and σπέρμα (sperma) "seed") is the hypothesis that life exists throughout the Universe, distributed by meteoroids, asteroids and planetoids.[1]



http://en.wikipedia.org/wiki/Panspermia


I rather like that hypothesis myself, it seems almost elegant and considering the extremes to which life can exist and even thrive I'd say it's a decent contender for the origin of life here. However that still leaves the question of where and how life actually may have originated.

To take the Questions in order:
?
do you think they exist? Almost certainly.
don't exist? Almost certainly not.
are visiting us? May be, although if they are, it'd probably be for purposes of Scientific research rather than because they'd want to make Contract, I'd sugegst.
not visiting us? Possibly not, although the balance of probability does, I feel, sometimes suggest rather strongly that there do seem to be some things flying about in the Atmosphere that give every impression of being intelligently controlled devices. Beyond that, i would not like to speculate. :innocent:

If, as it seems, we are in the process of becoming a totalitarian society in which the state apparatus is all-powerful, the ethics most important for the survival of the true, free, human individual would be: cheat, lie, evade, fake it, be elsewhere, forge documents, build improved electronic gadgets in your garage that’ll outwit the gadgets used by the authorities.

well you made that clear. (?)  Or maybe it was just the 3 space gaps between your words which made it awkward to read.

Yes I will state that I believe its a certainty that life elsewhere exists, heck we could even find something as close to us as Europa if we ever get a probe under the surface and into the water. WATER! A requirement for life! But it may only be microbial...and we wont know till we we go look, and thats probably a very long way off yet.

BUT even microbial life..is life!

The issue I have 'always had' is with visitation. I don't think its ever happened so far, as much as sci-fi films create fantastical space ships and FTL travel, well thats the bit I have trouble with. The sheer distances and logistics of such travel are staggering, even if you can travel at the speed of light.
