Is there life on other worlds? Are we alone in the galaxy?

Goldilocks Zone is a meme. There's a bunch of other variables like how many gas giants there are and where their orbits are. Or what kind of star is it and if it's in a binary system or not. Even one or two things can kill any chances of life developing. I'm not saying that there's no possibility of microbes developing, but global biospheres are a whole different story.

As I understand it, the formation of actual biological "life" would be very rare.

But in a galaxy with 100+ billion planets... Rare shit happens all the time

>Is there life on other worlds? Are we alone in the universe?
FTFY - why restrict yourself to one galaxy. Anyway,as Athur C Clarke said:
> "Two possibilities exist: either we are alone in the Universe or we are not. Both are equally terrifying"

most likely. the chance of life evolving into a stable ecosystem like ours are astronomical
>has to not be to close for it to even be possible
>has to not be too far away for it to even be possible
>has to be on a planet with a specific gravitational pull for it to even be possible (not too big or anything living would be crushed etc)
>needs to have specific substances available in the same place (water, protein, oxygen, iron, etc)
>proteins need to be lucky and form a form of a primitive machine which is able to reproduce itself and evolve

then if a planet get through this faze
>need to be enough variation of creations to kill of the unsuitable ones
>needs to be enough resources for the creatures not to go extinct (plants did this by giving us food and limitless oxygen, we give them food to by c02)

then they evolve like on earth after all these very specific essential needs are met. but we're not done
>needs to evolve a specific kind of animal with intelligence enough to make language
>needs to live in a safe enough ecosystem to not go extinct (homo Erectus, Neanderthals, and almost humans went extinct due to an unstable climate)
>smartypants alien needs to survive plagues and disease
>smartypants alien needs to not get killed by ice ages and stuff
>needs to expand to everywhere so they cant go extinct by things like plagues
>needs to survive in the woods for millions of years until it gets easier, with the brain of a dumb down syndrome 6-year old that gets 10 IQ more each 1000 year
>needs to not invent a bomb that can kill everyone on its planet and use it because of retarded tribe mentality reasons "they have this resource and killed this specific smartypants alien. I'll kill them all"

now they have achieved a civilization type 1. they can control the weather and nothing from the planet is a threat to their civ anymore. this will be humans when we have a stable civ on mars

>the chance of life evolving into a stable ecosystem like ours are astronomical
Except the number of galaxies (never mind individual stars) is literally astronomical. Billions in a single cluster. That's a lot of dice. In fact, it's easier to argue that if it happened once, it happened more than once

Factor in the billions of galaxies

This
I do believe there is life beyond the ice wall though

FERMI PARADOX

some scientist figured out mathematically approximately how many planets have life in our galaxy and figured it to about 20 if I remember correctly. now if you take the chance of these 20 planets evolving life to be interesting in any way, then I'm pretty sure this drops below 0. its one thing for it to develop life, but another for the life to thrive and survive as it has on earth. and it won't here either forever.

there are a lot of possible planets this actually is possible to happen, but the chance is still astronomical for it to happen at all. life is basically dust that happens to cooperate with other dust by chance that got more and more advanced.
