Help

I'm so confused. Someone explain it to me like I'm four （/TДT)/
Like...this whole thing feels paradoxical. So this whole thing already happened once, Aisha (Genus) and Hades falling in love, Hades reached the gates of reincarnation to kill the lizard and save Aisha from the pain, but he died. Aisha was pregnant with Abel, and then what? How did she turn back time? Or was it the lizard that turned back time after she begged him or something? And then she left Abel with Hades and killed herself because she didn't believe in God anymorep and supposedly that should have saved both Hades and Abel, but Procreator decided to save Genus and sent her soul to the world he created and then again to become Aisha but now she is a bit different having no memories of that past life, things are developing differently (but Procreator still gave her a novel with Abel's future)?
Like that's what I get, but the part I don't really get is how Genus turned back time.
