There are many animals that follow sensible survival strategies because they do certain behaviors by instinct, not because they're thinking things through and making plans. I see parallels to human behavior and ideas about religion and spirituality in all of this unconscious high performance in nature. People can study why other people or themselves are religious just like you can study why birds migrate. There's no conflict between science and religion there. The conflict comes when you say, okay, I have a goal,. I have an ambition to do the following thing, namely to correctly understand the universe.
