Ellie Arroway: I got one for you. Occam’s Razor. Ever heard of it?
Palmer Joss: Occam’s Razor. Sounds like some slasher movie.
Ellie Arroway: No, Occam’s Razor is a basic scientific principle which says: Things being equal, the simplest explanation tends to be right.
Palmer Joss: Makes sense to me. So what’s more likely?
Ellie Arroway: An all-powerful God created the universe … then decided not to give any proof of His existence? Or that He doesn’t exist at all and that we created Him so we wouldn’t feel so small and alone.
Palmer Joss: I don’t know. I couldn’t imagine living in a world where God didn’t exist. I wouldn’t want to.
Ellie Arroway: How do you know you’re not deluding yourself? I mean, for me … I’d need proof.
Palmer Joss: Proof? Did you love your father?
Ellie Arroway: What?
Palmer Joss: Your dad, did you love him?
Ellie Arroway: Yes. Very much.
Palmer Joss: Prove it.
