Our world would be a shambles. It is doubtful civilization would exist. Assuming a civilization could be built against all the interference of hostile entities hours of daily life would be extraordinarily consumed with the trappings of protection against evil forces. All the praying and hexing would barely leave time to eat a meal, much less forage for and prepare it.
Proof of life after death, angels and demons would be as obvious and physically evident as the sun. If those entities existed, eternal war would be the result with humans as pawns or casualties. Millions of people would be taken, killed or possessed by entities hostile to all that was good, shambling through the streets like extras in a George Romero film. Only the insane would act in a manner they know for a certainty would cause torment in limbo or fire as the proof of it would be in front of their eyes everyday and night without misinterpretation. But would the mentally ill or any disease even exist? In a world of magic they would be healed through faith and the laying on of hands or potions the moment symptoms manifested.
Physics as we know it now would be radically different than it is. No mysteries would remain as sensitives prove that they can cast their minds through time and space seeking answers and bringing back irrefutable evidence of the way the universe works. Their talents would not be negated, hindered or defeated by cameras, the nearby presence of unbelievers and double-blind tests. If any of the Woo was real it would not be hidden, it would obvious, verifiable and most of all reproducible. Like science is.
