What is the probability of alien life in our galaxy?

100%.
Out of the vast amount of planets out there, the same factors that made life possible on Earth can easily be replicated. It's absurd to think that life is only confined to Earth.

The universe is so stupidly huge. Like really, why is it this big? I think it's more unlikely that aliens do not exist.

The galaxy is massive. So, I don't really see why other life forms should not exist.

I would say pretty good chance. We would have to be ignorant to think we are completely alone and arrogant to think that we are that special.

Not probable. They do exist.

They don't come to talk to us for the same reason we avoid large ant hills. They think you are invading their home and will defend their territory.

To assume there isn't some other form of life out there is arrogance.

Absolutely. Now, will it be as romantic as everyone thinks? Most likely not. But basic life forms, single celled or small multi-cellular bacteria is pretty much guaranteed to be out there. All you need is a planet the right distance from a star, which isn't very demanding at all, given the number of them. Life isn't this impossible thing, it'll happen eventually, it just takes 4 or so billion years to get to our point.

The first 500 million years of our planet was lifeless. The next 2.5 billion was full of only super simple life, life that you wouldn't be able to observe from another planet. 500 million years of sea life later, only the last 500 million years had anything complex above the surface of the water.

The Milky Way is nothing compared to the size of the Universe, and yet our galaxy still has hundreds of billions of stars. It's a safe bet that many of them have planets which are in a nice comfort zone in orbit. Even now, intelligent life equal to our own could exist just a few solar systems away, and we'd have no way of knowing they even exist, let alone simple life.

Very Very Very High.
To think we are the only intelligent life in this MASSIVE universe filled with millions of undiscovered planets similar to is completely ridiculous and quite self centered.

While Drake equasion and such things are pretty flawed and unreliable... I think it's very likely. People tend to not graps the size of the galaxy and just how unlikely it is no other planet developed life of some description.

I'm too lazy to google some formula for this. I see that you are too, which is why you're asking it here.

probability of alien life in our galaxy =/= probability of alien life in the universe.
