I am pretty sure of it that we are not alone i this Galaxy. I know it has ALMOST nothing to do with Mass Effect. But i just wanted to tell this. Many of you may already know we are not alone. But here is the conclusion:

There are over Billion stars in this Galaxy...
Every star has a "Solar System" And every star also has a "Safe zone" That is a zone where life can exist in a safe region around the Sun. for example: Venus is too close too the sun.. So that is a danger zone because it's too hot. But Mars is too far away from the sun because it's too cold.. There are also different types of suns (3 types as far as i know). You have the blue suns which are very hot so the safe area is around where Mars is located. Then you have the yellow suns red suns. which are colder then the rest. So that means that the safe zone is closer to the sun. So if there are over Billion suns with solar systems. there must be life somewhere in the Galaxy. But it isn't said that there are planets located in those "Safe Zones".

We are not alone...
That what i think at least..

Please reply..
I may have forgotten some info but i like talking about this subject

Thanks.. 

Edit: It was very dumb of our ancestours (idk if spelled right) to make country's with a different langauge each..
In a couple of years we will all be speaking English. Or chinese.(i don't hope that we will all be speaking chinese.)
And call ourselfs Earthlings instead of Americans,Russians,Chinese etc..

Edit: Im only 15 years old and from The Netherlands.. So im sorry for being dumb. i guess?
don't ban or report me for this.. please?

I agree, the existence of alien life is probable. Ever heard about Drake's equation?

Stephen Hawking said that alien life exists and is hostile.

Not a pleasant thought.

[Tapkomet]

As I have heard, there can't be any life near blue stars. Too unstable, too short-lived. However, probability of any extraterrestial life existing is, like, a lot.

[Zix13]

It's likely, but the existence of intelligent alien life is far less likely.

Note also that this has become a more serious scientific inquiry for both cosmologists and biologists, since we should not limit ourselves to thinking of life only as that which we find on earth, and there may be life on other planets we would name "extremophiles", meaning life forms which can live in extreme conditions (to us). We have such examples here on Earth even, where smaller life forms have evolved to withstand temperatures that would melt metals, or pressures deep in the ocean which could crush a submarine into a coke can.

There may be many different forms of life, based on different elements. We are based primarily on carbon (carbon-based life) but there may be other chemical substances that can give "life", one cannot exclude it.

For me it is very interesting to see what we find in the future, it is a shame that our lives are restricted to roughly one century, and there is so much to discover out there.

I consider the existence of extra-terrestrial life to be a mathematical certainty.

The real question is whether we ever be able to contact them. The whole speed-of-light speed limit thing is a bit of a hurdle to get over.

Hey, maybe from the viewpoint of an alien that doesn't have our cultural/literary background, the endings might make sense!

Anyone that would swear otherwise (one way to really p me off) imo is arrogant, ofc we are not alone...

Your post made me think of Carl Sagan. Now I want to rewatch "Cosmos".

"There are some hundred billion galaxies, each with, on the average, a hundred billion stars, 1011 x 1011 = 1022, ten billion trillion. In the face of such overpowering numbers, what is the likelihood that only one ordinary star, the Sun, is accompanied by an inhabited planet? Why should we, tucked away in some forgotten corner of the Cosmos, be so fortunate? To me, it seems far more likely that the universe is brimming over with life. But we humans do not yet know. We are just beginning our explorations. From eight billion light-years away we are hard pressed to find even the cluster in which our Milky Way Galaxy is embedded, much less the Sun or the Earth. The only planet we are sure is inhabited is a tiny speck of rock and metal, shining feebly by reflected sunlight, and at this distance utterly lost. "

Estimated 100 Billion stars in our galaxy actually and an estimated 125 billion galaxies visible from our atmosphere.

if there is life in this Galaxy.. We have a problem of reaching that life.... It would take at least 1000 years more to develop that technology.

And if the rules of biology let us..

Look what humanity has achieved in i guess.. 400 years? maybe less.

What would you do if you find intelligent life for the first time??
kill it?
Noo ofc not!

there can be life on the planet near a blue star. But it cannot develop to Intelligent life because there isn't enough time

[TallonRoe]

Scientists are discovering exoplanets constantly. Out of so many solar systems in this galaxy, ours can't possibly be the only one to have life. We're not even 100% sure yet that Earth is the only place in our own solar system to have life- Europa And Enceladus are possible candidates for life. It's neat to think about.

[MaskofSkin]

The sooner we discover life, the sooner we stop referring to ourselves by country, religion and political ideology and start referring to ourselves as Earthlings, the better off we will be,

AFAIK the only other candidate than carbon for sufficiently complex molecules is silicon, and if silicon based life was possible it would seem likely that it would exist here (there's a lot more silicon than carbon on Earth).

What if they're like the Yahg and just want to eat us or something?

I hope there are friendly aliens out there. I wouldn't want to do a Tom Cruise and sprint from tripods! or have to fly with Jeff Goldblum and Will Smith to an alien mothership and upload a virus. Well, actually that sounds kinda cool. *Puts cigar in mouth* "We can't wait to whup ET's ass".

Then it is a good job that killing things is Humanities number one favourite past-time.

Only problem with that is that we know nothing about any of the variables.

I want to believe, but from what I've seen and from reading things like the Fermi Paradox, it seems as though intelligent life is very rare or just doesn't want to deal with us.

As stated in the Fermi Paradox, a semi advanced spacefaring society could populate the entire Galaxy with Von Neumann probes over several million years. Since Earth was formed billions of years after the Milky Way was already established, intelligent life should have already colonized the entire galaxy.

So then a few possible conclusions are:

Galactic Civilization arose but became extinct before Humans advanced.

Humans are the first intelligent species and will establish Galactic Civilization.

Humans are alone.
