Two Sides... All the Opinions
Was he raised in a religion? Does he believe in God?
2: no I don't
4: Probably not.
he seems a more evolved creature, he doesn't believe in a being on a cloud.
After some googling.. nobody knows because he has never said anything about his religion.
No clue. He's very private about his life.
Given he was born in Belgium, I'd say the odds favour no religion.
