Do you think that human genetics which gave us higher levels of abstract thought and language, also can sometimes make us vulnerable to indoctrination by irrational beliefs ?
Since you mention "genetics", about 10 years ago, an interesting study was carried out on morality in babies and toddlers by Yale University. The study concluded with a strong suggestion that humans are born with hard-wired morality. I take that babies are born atheists but are vulnerable to someone's or something's influence.
