Do other worlds exist?

do you think is there other world exsixt ?

Did you find out how many universes they are? Billions! Now, just imagine how many galaxies that would be, and then imagine how many earth-like plantes there are...trillions! Cool huh!

Well, if you look at all the galaxies that exist and the universes there are, to think that we are the only living beings is quite naive. So, yes I absolutely believe there is life out there.

It's a lot of space out there to be only inhabited by us. Its 50/50 either there is/ was life out there or were all alone. Maybe one day soon we'll know the answer.

I'd guess there are millions. I spend most of my free time imagining what they're like,

I don't think so

100% positivaly yes.

Each and every planet is a world of it's own...so YES definately.

I watched this on discovery some time ago...
let's say that the probability of having an earth-like planet in our galaxy is 0.000000001% :
if you take all of the planets in our galaxy system, devide 1 (our planet) by the rest of them, you get a pretty small number, but not a zero.
Then multiply this number by the number of galaxies existing in the universe.
You're getting to a 99.99999% chance of having another planet like Earth somewhere else.
