Why don’t we see new stars all the time

Question

So my understanding is that stars are born and die all the time with supernovae, black holes, etc. And we can see this in deep space all the time but why can’t we see that with the naked eye? Why are our constilations the same as when I was a child? If stars are born and die all the time in our universe Why don’t we have a new night sky every few decades? I know a stars life is long so not all stars will change in my life time but there’s no new ones born or no old ones that die close enough for us to see when we look up

Answer 1

The shortest-lived stars live 30-50 times longer than humans have even existed, so seeing star death is incredibly unlikely. As for star formation, that only happens in particular regions of space filled with dense hydrogen gas, so stars won’t just appear in the sky.
