Probably no lives were lost. The chance of there being a planet in the goldilocks zone of a star is very small, the chance of that planet then having the right atmosphere to sustain life is minute.

The supernova may have caused an extinction event in its region of about 500 light years, but even for that the chance isn't big.
We only have one example of life. If we ever get to AGI, we'll have two. It's not too wild to imagine that different, absolutely inconceivable lifeforms exist in ways of being we can not fathom!
Imagine thinking a galaxy with hundreds of billions of stars—each with planets—couldn’t possibly host life, or be the more likely option, just because we haven’t found it yet. The universe: ancient, vast, and full of possibilities. Your knowledge of it: smaller than a Goldilocks zone.
Yeah but don't misrepresent what "theplasmawolf" said. That whole galaxy doesn't count for your OP - it's not about whether life could exist around some of its hundreds of billions of stars. What counts is ONLY the particular star that went supernova plus some in its vicinity. Life very unlikely.
We know this galaxy. Well, actually we don't, but we know a little about this galaxy. We have no way of knowing if that's consistent. For all we know, there are a hundred billion stars in that galaxy, each with life bearing planets.
Again, you're using the stellar population of that entire galaxy as the basis for your argument and incorrectly applying it to a very very tiny sub-volume of stars close to the supernova. And your original "billions of beings lost their lives" implied advanced lifeforms, which is even less likely.
Probably, but life on Earth started when it had a reducing atmosphere. Nitrogen and carbon dioxide with significant hydrogen sulphide as well as ammonia and methane. Simple life, cyranobacteria that released oxygen. It also seems that extrasolar planets within goldilocks zones are reasonably common.
