Robert Sawyer’s-Calculating God-made us discuss the meaning of ultimate reality. The book takes place in the present day and describes the arrival on Earth of sentient aliens. The bulk of the novel covers the many discussions and arguments on this topic, as well as about the nature of belief, religion, and science. Thomas Jericho, a paleontologist working at the Royal Ontario Museum in Toronto, makes the first human-to-alien contact when a Forhilnor, a spider-like alien from the third planet of the Beta Hydri system arrives on Earth to investigate Earth’s evolutionary history. The alien, Hollus, has come to Earth to gain access to the museum’s large collection of fossils, and to study accumulated human knowledge in order to gather evidence of the existence of God. It seems that Earth and Hollus’ home planet, and the home planet of another alien species traveling with Hollus, all experienced the same five cataclysmic events at roughly the same time. Hollus believes that the universe was created by a god, to provide a place where life could develop and evolve. Thomas Jericho is an atheist who provides a balance to the philosophical discussion regarding the existence of gods.(source-Wikipedia)
