Do you know what the Drake Equation is? You missed the entire point, i think.
Even if you use very small possibilities for the variables the result is still a pretty big number - but divided by incredibly huge space it’s very close to zero density.
I have known the Drake equation since the first Cosmos series, back in the 70s.
I just know that (going by our only example...us) it takes a VERY long time, and, a VERY special set of circumstances, available elements and locations for life to be possible, not even talking about making to an advanced civilization capable of building a telescope, not to mention spacecraft.
All in all, I think the number of civilizations in any particular part of the universe isn’t going to be much higher than 1, with all the special factors needed.
Then you have to deal with the distance problem. Getting around the speed of light may be impossible. Generation Ships might get around it, but, that’s if we are lucky.
Its fun to speculate about such things, but, reality is a harsh mistress.

Sorry about the double post. We are having internet issues this evening.
