The lead scientist who discovered it (Lee Berger) certainly thinks they did; they haven't found any way they could have accidentally fallen in from the surface and there are no (or almost no?) bones from any other species. He further claims they have evidence of intentional fire use and rock art.
Approximately every other paleoanthropologist is extremely skeptical of this and also constantly mad him for other things like putting preprints on bioRxiv, having too many TV shows, going to space with fossils, etc.
On the other hand, every paleoanthropologist except him seems to run on a system where they never reveal any discoveries or share their work with anyone and take 30 years to write up what they have found in case someone steals their dig sites. It kinda seems like he's right.
