The imagination is a powerful tool. Creative. Insightful. Able to ponder unfathomable problems and complexities.
So ponder this.
Our galaxy is made up of billions (yes billions) of star systems.
And yes, I mean planetary systems. We are learning that most stars are likely to have planets.
But it doesn't end there.
Our galaxy is only one of billions of others. Yes, billions.
So there are literally billions of galaxies, each made up of billions of stars.
Now, let me put two scenarios to you.
Firstly, that there is no life anywhere in the galaxy, or even the universe, except that which is found here on Earth.
Secondly, that life is a naturally occurring phenomenon. It appears when the building blocks, the causes and conditions upon which it depends, are present.
I know what I think: that one of those scenarios is utterly implausible.
How about you?

I think i what i learned is that human life form can only survive on planet earth. They are other life forms on other planets but only on earth its human survival possible.
So it is indeed implausible.

Well I believe in different alien races and lives in different planets. Even if we cant see them for some reasons, they are alive. All ancient civilizations spoke about them and saw them. Did you hear about the "Star Children"? I think they are the most advanced humans who know a lot about the universe.
There are different dimensions and in everyone of them different lives and species. What we need is enlightenment to see them :)

There is a good article about this in the latest NatGeo.
From my Uni days it always fascinated me that life occurred pretty much as quickly as it could have after the whole snowball earth situation.
I was always aware of the Goldilocks principle in our own solar system for earth's position, and proximity to the sun. The influence the moon has on our stability. And the fact that our Sun is the right size to remain stable for the time it took for complex life to occur.
And yes, in a universe expanding out from a big bang there is a high likelihood of other fortuitous planets in other parts of the universe or indeed our own galaxy.
The thing I found interesting about the latest NatGeo, was the second aspect to the Goldilocks principle of the position of our solar system in proximity (or rather the safe distance away from) to catastrophic/volatile areas of the galaxy.
Also the realisation that as our species has progressed we tend to output less not more radio noise into the abyss.
This makes me realise, that much in the same way that contesting whether there is, or is not, a "God" pulling the strings being what we call reality, that proof of extra terrestrial life is so far beyond our current technological ability to prove, or disprove, beyond reasonable doubt.
In such circumstances I always remain open to being pleasantly surprised. Narrow mindedness is what kept us believing the world was flat after all.
That said, based on the fact that life evolved here as quickly as it could have, and discount all setbacks due to war, and other events on earth. So assume a planet that had no mass extinction events and a direct evolution into sentience, it is plausible that a race could have evolved to be 100,000's of years more technologically advanced than our own. How long it takes to them to possibly figure out FTL? Or maybe assume that they do not have the same aspirations for conquest and exploration as humans do? Would they ever leave their solar system if they could just expand gradually by harvesting asteroids, and establish one other colony to protect against a mass extinct events at a star far enough away to get to if they detected something on a galactic scale that they couldn't control. Ie lets assume they could deflect an asteroid from hitting their home planet (they are mining them after all in this scenario). But that they couldn't yet stop something on a bigger scale.

All of this rambling, and yes I do believe that there is something out there. Will we ever stumble across one another. If they are in this galaxy then I say yes within a period of 10,000's of years. If they are in a different galaxy, then the odds are well....

Yes, one of those scenarios is entirely implausible and the height of human arrogance. Well penned. Nice image choices.

our own existence is a testament to life can exist our there.
we barely began to scratch the surface of our probe into outer reach...
and to limit our thinking otherwise is pretty mind numbing.

interesting post, personally I believe there exists another form of life apart from us.
