While America continues to dish on millennials this Halloween for being too sensitive about costumes, there’s a growing concern about the 18-to-29-year-old age demographic losing their religion and adopting the occult.

According to a Pew Research Center survey, more adults think a belief in God is not necessary to have good values and be a moral person. A growing share of millennials between 18 to 29 is starting to doubt the existence of God. From 2007 to 2012, the portion of young people who never doubted God’s existence dropped from 81 percent to 67 percent.
