Haha, they must not've been a fan of Galactica 1980. No mention of the battlestar Galactica's arrival at Earth during that time.
Clearly the author(s) was/were new series fan(s). In fact, in the entry that was made for 150,000 years into Earth's past, they mention that Hera becomes the "Mitochondrial Eve". (Suggesting that they were also fans of the videogame "Parasite Eve".)
