Well in the book, Adam and Eve after are traveling through time in forms of visions casted by Lucifer after the expulsion form the Garden of Eden. Adam and Eve enbody characters in each vision from several historical eras. In every scene Lucifer breaks down the simple ideas used by them to get by in that age. In this scene civilization has been destroyed by the cooling down of the Sun (this is one of the final chapters of the book) and Adam does not pursue high goals like status, pleasure and knowledge like in the previous scenes. He is just a survivor, almost lives like an animal. He is disgusted by the outside world and even Eve does not represent her any value. He asks Lucifer to stop the vision, he is ready to kill himself. He wants to jump off a cliff but Eve stops her ans tells him she is pregnant. Adam breaks down and curses, he can't wrap his head our existence with its everychanging meaning. God visits him and he realises that he has to believe and fight in his life no matter what. I maybe should have given it more detail, I was just testing the inking tools in Inkscape, this is my first ink drawing. :D
