Yes, there are many, many people who truly need to believe in deities, miracles, heaven, hell, ghosts, vampires, werewolves, Abbot & Costello (well, maybe not the last), because without those irrational beliefs, the observable physical universe is either too chaotic or too banal for them to bear.
And there are others for whom the observable physical universe is just fine, in no need of imaginary gussying up.
It usually seems that the first group is the majority, doesn't it?
