I totally believe there is alien life. Like, why would we be the only life in the universe. I think life is everywhere from simple cell organisms to advanced civilizations that travel the stars.

I believe it also! And I know there are!
And, btw, if we were the only ones in this whole wide universe, then it would be an awful waste of space!

That our planet would be the only one where there is life, well that chance is so minimal, that it's hard to believe. Maybe the first life on this earth came to earth by a comet? Like a seed that didn't burn. Maybe the ozonlayer wasn't that thick in these days. So comets falling on the earth wouldn't be that hot. Falling stars are little pieces that are falling into the ozonlayer, causing friction.
I am quite sure there is sentient life elsewhere. Consider this,however, how long has there been life on this planet and how long have we had this non-space-faring civililization of ours? And in my opinion there's a goldilocks zone for galaxies. Oh, there could be civilizations so unlike us they're going strong but do not affect us and have no interest in us, nor would we care if we found them. So I would disagree that there is anything close or likely to visit us.

I like to believe that we're the most advanced life in the universe and that's why we don't see any aliens. I'm 80% sure that technology kills all life stone dead, 99% if I otherwise have to believe that they're up there cloaked.

English physicist Brian Cox believes we won’t be contacting intelligent extraterrestrials — nor will we hear from them — anytime soon (or perhaps not ever). Cox, the popular presenter of several science programs, is an Advanced Fellow of particle physics in the School of Physics and Astronomy at the University of Manchester.
“It may be that the growth of science and engineering inevitably outstrips the development of political expertise, leading to disaster,” says Cox. He believes that intelligent extraterrestrial life may have unwittingly rendered themselves extinct. Intelligent life destroys itself as soon as it becomes advanced, the physicist believes, “we could be approaching that position.”
The Fermi Paradox
The vastness of space and the possibilities it holds are the very heart of the Fermi paradox — a 1950s theory named after physicist Enrico Fermi who famously pointed out how, despite the strong potential for extraterrestrial life, there is an equally strong lack of evidence showing that it exists. If alien life is out there, why haven’t they contacted us, yet?
“One solution to the Fermi paradox is that it is not possible to run a world that has the power to destroy itself and that needs global collaborative solutions to prevent that,” Cox explains. While this explanation makes a lot of sense, there’s still a chance we might encounter extraterrestrial life, albeit not in intelligent forms.

Oh that's a big question. So much to factor in...and out...
Earth's recent history (millions of years that is ) has mostly been one ice age or another.We're only here because this period is a rather long warm period within an ice age. Anthropogenic global warming is, contrary to popular belief, to our benefit, both short term and long term as it's keepng the planet warm, thus extending what should be a decline in the earths temperature. Our being here is breathtakingly amazing...but we are. So what are the odds of another earth being out there where conditions were just right and in the goldilocks zone too..that's crucial to life...
All life on earth can be connected by the commonality of genes, humans share 99% with chimps and we even share about 25% of fruit fly genes...Octopus genes however are a real mystery though as they have no connection with any life on earth..so where did they come from?
The size of the Universe....if earth were the size of one grain of sand on the beach, the Universe (capital U) would stretch to Jupiter, the universe (small u) would stretch to the moon (neither are correct measurements, just designed to give an idea of just fast the Universe/universe is..yes there is a difference in size. Given the sheer scale and abundance of galaxies, the odds are there must be at least one other planet where similar co-incidences occured that resulted in intelligent life...then again...given those set of circumstances, it's equally likely there's no life out there as just one missing co-incidence could mean the conditions aren't right for life to kick off....
Earth is absolutely swarming with life from sea bears to plant life to humans there isn't a square inch of the planet that hasn't been colonised by some sort of liife form....if life can coloniise this planet so easily and quickly...then how hard can it be for life to start elsewhere.
Our solar system is structured in such a way that it acts as a 360 degree protective barrier.. thus really increasing our chances of survival....if e.g. we didn't have Jupiter hoovering up thousands of errant meteors there's be zero life on earth...
We've traced our genesis all the way back to the sea and very simple life form...nature and adversity forced life to continually evolve to adapt...and we are still evolving.unfortunately our cerebellum is evolving far far far faster than our amygdala....hence the constant arguing..and why majority voting is wrong...and we've lost at least 3- 5 other species of human being along the way...Denisons, neanderthal etc....and the planet was far more a volatile environment back then....So if there were mulitiple species of humans here... then.....
Factor in the fact that silicon and carbon are so similar.....carbon being the orangic one and what our life is based on...but who's to say silicon cannot be some other planet;s basis to life if the conditions are right for a silicon based intelligent lifeform...
The octopus is the one that gets me though...where on earth did those genes come from as they are clearly not of this planet....
What worries me, is the fact that we have been sending radio signals out into space for about 100 years now.....so that's 100 light years...Radio tramissions are basically light, so common to every solar system. If that signal is picked up by another life form, and that life form is as aggressive and hostile as humans are..and it manages to get here (expansion rate of the universe might make that impossible though as galaxies are moving further apart at incredible speeds) then we might be in trouble...so lets hope if there is other life out there and it can get here..that it's smarter than us,but a lot less aggressive :)
blathin: Oh that's a big question. So much to factor in...and out...
Everything you said is true and there is even more to factor in. On earth right now there are organisms called extremophiles that can live in extreme conditions that would kill everything else. They can be in a oxygen free environment, extreme heat, cold, toxic, poisonous environments and thrive. They could easy survive places where you think life would be impossible like volcanic vents under the ocean where it gets hot and is extremely toxic and poisonous.

That is exactly what I've been saying all along. We are sending signals out there hoping some one or some thing will respond thinking it's going to be a little green ET fella.
Chances are it won't be ET. It could be a very aggressive thing that wants to tear your body apart and eat it. Hoping for an alien you would see on Star Trek that Captain Kirk would welcome onto the Enterprise is unlikely to happen.
I think the alien we will find will be more like the one Sigorney Weaver had to deal with in her ALIEN movies. That thing always scared the beejesus outta me

Ah no Secret agent don't go saying things like that lol..that's one really scary film..that I never watched lol...
yeh, and I always wondered should we be keeping quiet about our being here on this beautfiul oasis of abundant life and colour.. ..
I do wonder though if the smarter a species is, the less aggressive it needs to be?..With us humans, our primtive brain the emotional limbic system is what makes us aggressive, not our rational brain....however pure rational thoughy is nuanced by our emotions....so it depends on their rational/emotional ratio or development..I would hazard a guess anyway..Really interesting topic though...:)

Extremophiles? ohGod yeh they're amazing aren't they..it's hard to believe life can actually survive those acid lakes and ocean bed chimneys...Have you ever heard about Sea Bears?...I can't remember their proper name...it's telegrande or something like that... Now they are utterly fascinating...they are tiny little insect like things..and have some amazing things they do to survive... they can even amend/fix their own DNA depending on what environment their in, or just dry out, curl up and go to sleep for ..I dunno...millenia maybe..
There's a video, must be at least ten years old now...called the Life of the Cell..it brings the cell to life.... ...if I can find the link I'll put it for you if you like.it's a really amazing vid...it's like a whole other world going on inside one single human cell.....mitchondria cell if memory serves..
There, there Tom Catty, it may seem like that but that's only because it's true. The Human is alone. Not the only, just alone; and all on your own devices. W.

We have to appreciate how much more doomed we are if many have reached the stage of development that we have, and then not made it. Their absence is explained by our being the early bird or that aliens simply don't exist. Salvation as I see it is only possible if the Earth is in some sense special.
People from the same country and even from the same family have hard times to communicate with each other or agree on something however little and insignificant. We ARE alien to each other.
