The nameless Namekian was mostek likely of the Dragon Clan before hi split, since both Kami and Demon Kind Piccolo are. But Piccolo Jr. who is DKP reincarnated is a Warrior Clan namek. And then he merges back with Kami, effectively becoming the same namek as at the beginning(+Nail) but of the other Clan.

T.l.d.r. Piccolo is trans by Namekian standards.

But we also know that probably at least half of Earth's population died out during the mission (from the cold, the infighting, the lack of food) it's quite likely a lot of works of culture would be destroyed as well, from important books and movies to games and YouTube videos.

Imagine, that decades if not centuries after the sun was "saved", Humans established a semi regular communication with Erid and find out that they just casually have an enormous amount of what was perceived as lost media.
