If stars we see are billions of years dead, what is really out there now?

They say that when we look up to see stars, we’re actually seeing the light from dead stars. So technically, we can’t see what’s out there in the present? What do you think is out there now? is it just new, modern stars or we don’t get to see anything at all? (since by now, everything has expanded billions of miles apart from each other that light is far from anything to reach)

I just want to add that the vast vast vast majority of stars you see with your naked eye are within like a few hundred light years. So their light left a ~hundred years ago, not billions. Even the Andromeda galaxy, which is perhaps the farthest thing you can see without a telescope, is only 2.5 million light years away.

So almost everything you see without a telescope is still there, just a little bit older than what we see.
