There's quite a bit of evidence that Homo sapiens, denisovans, and floresiensis might have coexisted in Sundaland (the land mass containing much of Indonesia before the oceans rose and created the SEA islands) at the time but the cave art is more consistent with Homo sapiens in the rest of the world than either of the other two. That's the default conclusion until more artwork conclusively belonging to other species is discovered.
