No, why? Unless its in your teachings, you don’t have to believe in the supernatural. Theist can be skeptics too. I suspect you are one of those atheist who is stating that as theist believe in such “redonkyless” things as the flying spaghetti monster we have to believe in big foot,spacebears,fairies… .
But ask yourself this ‘Is it not more contradictory for atheist to believe in the supernatural?’ And yes, there are quite a few.
