Bruce is pretty absorbed in this book! He was hoping for a sensible, detailed, clear-headed laying out of the situation regarding Jesus, miracles, the afterlife, why some people say they're Christian but act like they're pretending without knowing what they're pretending about, etc, and that's what he got. Aaaaand unless it's a very detailed fraud, about things that anyone who grew up here would be able to call out as a fraud, the world looks exactly how you would expect it to look if people had just appeared out of nowhere at random and some of them had written the Bible by the same processes that made heathens come up with stories about heathen gods, and actual God had had no involvement. He remembers another science fiction story, this one a horror piece about a world where God withdrew entirely from the universe after the Fall and the Bible never existed. Maybe something like that happened here: a world whose Creator lost interest in both the living and the dead.
He props one elbow on his knee and his chin on his hand to think about it. His other hand goes absentmindedly to pet the soft thing next to his other leg.
