We have found none so far, and none have found us; but, that is to be expected given the age and enormous expanse of the universe. The probability though, is that there are millions of advanced civilizations out there.

well, there are probably billions (and counting) we just don't have the technology to find them. In the future, many life forms will be present on earth but for now, we don't know. If you define living as something that has a cell, then we can name thousands now, but if you mean living civilizations as in extraterrestial life, then none have been discovered yet

this is a miracle itself that we not only had life here at Earth but also intelligent enough to explore things on there own.
We are familiar with the carbon based life on planet Earth.
Just like this according to the rule of probability there are pretty good chances at other distant parts of universe to have a similar condition to foster life forms.
May be that world consist of entirely different kind of matter and consequently its life form may be based on any available material.

It all depends on your definition of a civilization.
If you considered Earth as one civilization and took a worst-case-scenario to say there was a 1 in 1 trillion chance there was another world out there just like ours, then there would be another planet in our own galaxy just like ours, and every other galaxy out there as well.
So a worst-case-scenario says at least one per galaxy.

Only one that we know of, probably millions more from what statistics tell us (most more advanced since we're only a couple thousand years into our "advanced civilization").
