We don't know that happened to them, or to any other human species for that matter.
But we're pretty sure we obliterated a entire species in our way up the food chain ( giant marsupials for example)

Humans had the power to exterminate many more but chose not to, and continue to choose not to.
Saying "we didn't kill them all" doesn't exempt the fact that we did it for many of them.
There's no easy answer to this. We are what we are. But it points to the disregard powerful beings have over weaker ones when they get in their way.
Especially the predators that compete with us.
