Atheist Memes

Before achieving through abnormal circumstance a godlike omnipotence and omnipresence, the Ellimist was originally a Ketran named Toomin. He lived on the Equatorial High Crystal with his friends Inidar, Aguella and Wormer. Toomin could be best described as a "gamer"; he frequently played a life simulation game called Alien Civilizations, very popular among his people, which gave each player an alien species and tasked them with slightly modifying their environmental or evolutionary aspects, so as to cause change over time. The aim of the game was to keep the species alive for as long as possible; if the species became extinct, the player lost.

So, far before the main storyline of Animorphs, the ancient backstory is roughly 'once there was a race hyperintelligent elf-dwarfish creatures, of whom some played very advanced life simulator / god games, and, following a series of extraordinary events, the last remaining one of their kind basically became an actual god / a dimensionally transcendent being.'

... and, the particular one of these that ended up essentially becoming god, well, he was originally ... pretty much a hikkikomori NEET nerd 'failure to launch' 'professional gamer' kid/adolescent, going by the cultural standards of his species, before it was genocided.

So... its like an ancient alien dork who was really into life simulator / god games just ended up gaining so much knowledge and power that he became able to treat reality itself as one of his games.

Kind of. Sort of. Its more complicated and strange than that.
