How many Intelligent Alien Species in our Galaxy are there?

Dear World,
I think everybody has wondered looking up, if any intelligent Alien Species in our Galaxy exist.
Maybe facing the same Problems as we do. I think it is also because we would like to have some guidance.
Somebody who figured things out and can tell us what is the right thing to do.
Otherwise or responsibility would be too big. What if we are really alone? What if we are the ones that got the farthest.
Maybe all other intelligent Species in the Universe was not so lucky to get that far.
