Depends on how you look at it. We are descendants of Neanderthals (at least if we have European or Asian ancestry). And we are still here.
It’s like dinosaurs, are they extinct? Tiny dinosaurs are chirping in the trees in my garden right now.

That's not true with modern humans and neanderthals. A tiny amount of their dna remains in some human populations, but neanderthals are not the common ancestor of all humans. We are all descended from early homo sapiens and the tiny amount of neanderthal dna that persists is totally swamped by the homo sapiens dna.
