" I don’t think that necessarily would make Reed more likely to believe in divinity, but rather in one more avenue of science and existence that he doesn’t fully understand yet." If he still believes that there is no afterlife in the MU then he is not acting like a proper scientist. There is penalty of observable and testable things in the MU that can lead him to that answer. It seems weird for him to deny it in a world where people come back to life and souls can be proven to exist.
