Hao Ren did not pay much attention to the term that appeared out of nowhere when he first heard of the 'Denizens of the Stars'. Even when he found clues about them in the ruins of the other civilisations, he still had not paid much attention to them.

The Denizens of the Stars had ran out and about trying to save those that were threatened by the apocalypse, and this was something any race with sufficient capability and heart could accomplish.

They were not just special in their technological capabilities, they were special in their relationship with the Goddess.
