You're the stellar modeler here. However, we're second or third
generation? I do not see how you could have had a noticeable population of
of systems with the amount of small wet rocky worlds in the olden times.
The material had to be passed through several times to enrich on the
heavier elements. Plus, young galaxies are too bright for life. Plus, life
needs a lot of time to progres to level which is interesting. Unless we're
extreme freaks.

Dunno, I think due to multiple factors delayed hatching is real.

I think we don't have to jump through a lot of hoops to show why we don't
see aliens who're out there. Much simpler explanation is that we're in
nobody's light cone. We wouldn't be able to observe it, anyway. I guess
this forebodes ill to anything within our light cone pretty soon.
